Opis:

Saponaria officinalis L. is a medicinal plant from the family Caryophyllaceae. It occurs in most European countries, as well as in North Africa, America and Western Asia. The aim of the study was to find an optimal method of sterilization S. officinalis seeds in order to obtain sterile seedlings and to multiply axillary shoots from nodal explants isolated from them, on MS medium with the addition of growth regulators (RW). In this study, 4 variants of seed sterilization were compared using NaClO at the following concentrations: 1.5% (2), 2% (3) and 2.5% (4) for a period of 11 minutes. The control was a variant in which 70% C2H5OH was used for pre-sterilization for 1 minute (1). The highest percentage of sprouted, seeds and sterile seedlings and the lowest percentage of contamination were obtained in variant (4). As a result of micropropagation of soapwort in in vitro cultures, axillary shoots were formed from nodal explants from axillary buds. The highest percentage of explants with shoots (95%) and callus tissue (48%) and the highest number of shoots from one explant (5.95) were obtained in the second passage on MS medium with the addition of 4 mg.dm-3 BAP and 0.5 mg.dm-3 NAA. Due to the wide possibilities of using soapwort, it is advisable to continue research aimed at developing an optimal and efficient plant regeneration system of this species.

Opis:

Nowadays, the use of natural polysaccharides in the field of agriculture has increased in order to achieve sufficient yields and quality. Minimal research on effect of biopolymers on growth ornamental plants has been published. Verbena bonariensis L. is a valuable perennial species, recommended for cultivation in gardens and green areas, as well as cut and pot plant. The main objective of the investigation was to analyzed the effects of three polysaccharides on the growth and flowering of V. bonariensis. The plants were sprayed with aqueous solution of chitosan, gellan gum or kappa-carrageenan at a concentration of 0.2%, five times. Control plants were treated with water. The results indicated that polysaccharides significantly enhanced the plant height, number of inflorescences and number of leaves of V. bonariensis plants. Application of chitosan and gellan gum significantly increased the stomatal conductance by 13.8 and 16.3 % and enhanced the number of shoots per plant by 29.4 and 37.5 % compared with that control, respectively. Among the three polysaccharides, gellan gum proved best and gave significantly maximum fresh weight of aboveground part and fresh weight of root by 34.3 and 114 % over the control one.

Opis:

Plant growth-promoting rhizobacteria (PGPR) isolated from the rhizosphere soil of eight field crops at different locations in Egypt were identified. Rhizobacteria strains were identified as Bacillus endophyticus AW1 5, B. filamentosus EM9, ET3, Micrococcus luteus KT2, FW9, FC13, SaW4, Enterobacter cloacae SK18, Pseudomonas azotoformans TPo10, Citrobacter braakii TC3. All isolates solubilised insoluble phosphate and produced IAA, while only six were able to produce siderophores in vitro. Vegetative growth and yield of wheat cv. ‘Sakha 94’ were enhanced after the application of single inoculation of each isolate compared to the control. Grain yield was increased by 20.7-96.5% over the control according to bacterial isolates. Available phosphorus (P) and counts of total bacteria in soil were observed to be significantly increased in treatments than in control. After the wheat harvest, soil pH was observed to be decreased, and a highly significant negative correlation was observed between soil pH and the levels of available phosphorus. Significant increases in grain and straw yields, as well as uptake of nitrogen (N) and P by plants, were observed due to inoculation with PGPR isolates. Levels of photosynthetic pigments, free amino acids, free phenolics, and reducing sugars in flag leaf and spikes were significantly enhanced by the application of all PGPR isolates compared to the control. Thus this study identifies the PGPR isolates for the improvement of the growth, yield, and quality of wheat. The study may be also useful for field evaluation under different soils and environmental conditions before generalising PGPR isolates as biofertilisers.

Role of silicon in plant resistance to water stress

Tematy:

Opis:

Agricultural productivity is strongly affected by different abiotic stresses, among which water stress is the major environmental constraint limiting plants growth. The primary reason for water stress is drought or high salt concentration in soil (salinity). Because both of these stress factors lead to numerous physiological and biochemical changes in plants and result in serious loss in yields, there is a pressing need for finding the effective ways for increasing crops’ resistance to stress factors. One of the alternative methods involving alleviation of negative stress effects might be application of silicon as a fertiliser (root or foliar supply). Many plants, particularly monocotyledonous species, contain large amounts of Si (up to 10% of dry mass). In spite of the high Si accumulation in plants (its amount may equal concentration of macronutrients), until now it has not been considered as an essential element for higher plants. Many reports have shown that silicon may play a very important role in increasing plant resistance to noxious environmental factors. Hence, Si is recognised as a beneficial element for plants growing under biotic and abiotic stresses. The main form of Si which is available and easily taken up by plants is monosilicic acid (H4SiO4). Plants take up Si from soil solution both passively and actively. Some dicotyledonous plants such as legumes tend to exclude Si from tissues – rejective uptake. These plants are unable to accumulate Si and they do not benefit from silicon. Under water stress conditions, silicon might enhance plants’ resistance to stress and ameliorate growth of plants. These beneficial effects may result from better and more efficient osomoregulation, improved plant water status, reduction in water loss by transpiration, maintenance of adequate supply of essential nutrients, restriction in toxic ions uptake and efficient functioning of antioxidative mechanisms. Based on the current knowledge and presented data, it can be concluded that the role of Si in plants is not restricted to formation of physical or mechanical barrier (as precipitated amorphous silica) in cell walls, lumens and intercellular voids. Silicon can also modulate plants’ metabolism and alter physiological activities, particularly in plants subjected to stress conditions. However, in some plants, increased silicon supply does not improve plant growth. Hence, a better understanding of the interactions between silicon application and plant responses will contribute to more efficient fertiliser practices, especially under stress conditions.
Produktywność roślin uprawnych jest w znacznym stopniu ograniczana przez różne abiotyczne czynniki stresowe, wśród których stres wodny jest jednym z głównych problemów, na który narażone są rośliny. Stres wodny najczęściej jest spowodowany suszą glebową lub nadmiernym zasoleniem gleb. Ponieważ te czynniki powodują liczne fizjologiczne i biochemiczne zmiany w roślinach oraz prowadzą do poważnych strat plonów, konieczne jest znalezienie skutecznych sposobów zwiększenia odporności roślin na stresy. Jednym ze sposobów pozwalających na złagodzenie ujemnych skutków stresu wodnego może być zasilanie roślin krzemem (w formie oprysku lub dodatku do podłoża). Wiele roślin, szczególnie jednoliściennych, zawiera duże ilości krzemu (do 10% s.m.). Pomimo że procentowa zawartość krzemu w roślinach może dorównywać zawartości makroelementów, to nie jest on uznawany za pierwiastek niezbędny do prawidłowego wzrostu i rozwoju roślin. Wyniki wielu badań wskazują jednak na ważną rolę krzemu w podnoszeniu odporności roślin na różne niekorzystne czynniki środowiska. Dlatego krzem jest uważany za pierwiastek wpływający korzystnie na rośliny, szczególnie poddane działaniu abiotycznych i biotycznych czynników stresowych. Główną formą krzemu dostępną dla roślin i łatwo przez nie pobieraną jest kwas ortokrzemowy (H4SiO4). Może on być pobierany z roztworu glebowego w sposób pasywny lub aktywny. Niektóre rośliny (głównie motylkowate) wykluczaj¹ krzem ze swoich tkanek (ang. rejective uptake). Rośliny te nie mają zdolności akumulowania tego pierwiastka, i w związku z tym nie mogą doświadczać jego korzystnego działania. W warunkach stresu wodnego krzem może zwiększać odporność roślin oraz poprawiać ich wzrost. Ten pozytywny wpływ może wynikać z: lepszej i bardziej sprawnej osmoregulacji, lepszego statusu wodnego, ograniczenia strat wody w procesie transpiracji, odpowiedniego zaopatrzenia w składniki mineralne, ograniczenia pobierania toksycznych jonów oraz sprawnego funkcjonowania mechanizmów antyoksydacyjnych. Opierając się na obecnym stanie wiedzy i przedstawionych danych, można stwierdzić, że rola krzemu nie ogranicza się jedynie do tworzenia mechanicznej lub fizycznej bariery (w postaci amorficznej krzemionki) w ścianach komórkowych, przestrzeniach międzykomórkowych oraz wewnątrz komórek. Pierwiastek ten może wpływać na metaboliczną i fizjologiczną aktywność roślin, szczególnie tych, które narażone są na niekorzystne wpływy środowiskowa. Jednakże w przypadku niektórych roślin nie stwierdzono pozytywnego wpływu krzemu na ich wzrost. Dlatego zrozumienie interakcji między zastosowaniem krzemu a reakcją roślin na ten pierwiastek przyczyni się do bardziej efektywnego nawożenia roślin, szczególnie w warunkach stresowych.

Opis:

A study was conducted at the Department of Horticulture, KNUST, Kumasi from June to November, 2015 with the objectives to (i) determine the rate of ATONIK plant growth regulator (PGR) suitable for high yield of two varieties of hybrid rice (ii) determine the combined effects of PGR rates and varieties on the growth and yield performance of hybrid rice. A 2 x 5 factorial arrangement in randomized complete block design with three replications was used. The factors were varieties at two levels: Agra Rice and Jasmine 85 and PGR at five levels: ATONIK at 450 ml/ha, ATONIK at 500 ml/ha, ATONIK at 550 ml/ha, ATONIK at 0 ml/ha and GA3 at 60 ml/ha. Comparing the ATONIK rates with the GA3, ATONIK at 450 ml/ha resulted in a 14.3 % increase in the number of rice panicles. Application of ATONIK at 450 ml/ha, 500 ml/ha and 550 ml/ha resulted in 14.4%, 10.7% and 4.4% higher percentage of productive tillers, respectively, than that produced by GA3 at 60 ml/ha. ATONIK at 450 ml/ha application led to a 17.8 % increase in grain yield. For the harvest index, application of ATONIK at 450 ml/ha resulted in the highest harvest index of 45 %, significantly greater than the other PGR treatments. In conclusion, the study clearly demonstrated that ATONIK PGR was superior to GA3 in the vegetative and productive performance of rice. The most suitable rate of ATONIK for increased rice productivity was 450 ml/ha.

Leucocoryne coquimbensis F.Phil. ex Phil. is an attractive bulb plant which naturally occurs in Chile. It has ornamental blue or violet fragrant flowers. No information has been available on the use of plant growth retardants in the cultivation of L. coquimbensis as potted plant. The objectives of this study were to determine the effect of flurprimidol on plant growth and flowering of L. coquimbensis grown in pots in the greenhouse. In summary, it can be concluded that L. coquimbensis can be cultivated as an attractive pot plant. The use of flurprimidol modifies the appearance of L. coquimbensis, the flowering time and the quality of flowers. We recommend for producing potted plants the application of Topflor 0.1% as foliar spray when the plants was 3 cm tall.

The research was aimed at determining the influence of chitosan with different molecular weights on the growth and yield of flowers and corms of ‘Gompey’ freesia cultivated in pots. Freesia corms were soaked for 20 minutes in 0.5% chitosan solutions with low molecular weight (2 kDa), medium molecular weight (50 kDa) and high molecular weight (970 kDa). The average deacetylation level of the chitosans used was 85%. The plants were cultivated under controlled conditions (18/16 °C day/ night, relative air humidity of 60%, quantum irradiance of 90 μmol∙m-2∙s-1 with a light/ dark cycle of 14/8 hours). The research results obtained have shown that chitosan is used as a biostimulator in the cultivation of potted freesia. Regardless of the molecular weight of the compound, the chitosan-treated plants had more leaves and shoots, flowered earlier, formed more flowers and corms. The application of medium- and high-molecular-weight chitosan resulted in higher plants with a higher relative chlorophyll content (SPAD). The highest increase in the corm weight was observed as a result of treating plants with high-molecular-weight chitosan. No chitosan influence on the length of the main inflorescence shoot or the inflorescence length was observed.

Opis:

Zinc is a vital micronutrient for all life forms, and Zn-solubilizing bacteria (ZSB) present in the soil convert inorganic zinc into forms available for plants. This study assessed ZSB isolated from cow dung for their plant growth-promoting (PGP) characteristics and potential to enhance tomato plant growth. The experiment assayed a total of 30 bacteria from cow dung for Zn-solubilization using insoluble ZnO and ZnCO3. Atomic absorption spectroscopy quantitatively evaluated Zn-solubilization, and the isolates were further studied for Zn-solubilization and plant growth in Solanum lycopersicum. The CDS7 and CDS27 isolates were the most significant Zn solubilizing strains. CDS7 exhibited increased ZnO solubility (32.1 mg/l) compared to CDS21 (23.7 mg/l). PGP trait quantitative results revealed that the CDS7 and CDS21 bacterial strains solubilized insoluble phosphate (287.2 and 217.7 μg/ml, respectively) and produced indole acetic acid (22.1 and 14.8 μg/ml, respectively). Based on 16S rRNA gene sequencing, CDS7 and CDS21 were identified as Pseudomonas kilonensis and Pseudomonas chlororaphis, and 16S rDNA sequences were submitted to the GenBank database. Furthermore, ZSB strains were administered to tomato seeds under a pot study. The treatments with CDS7 inoculant and a consortium of both isolates were reported with maximum plant development (stem length 63.16 and 59.89 cm, respectively) and zinc content (3.13 and 2.36 mg/100 g, respectively) in tomato fruit compared to the control. In conclusion, microorganisms isolated from cow dung with PGP activity can improve Zn bioavailability and plant growth sustainably. They can be used as biofertilizers in agricultural fields to improve plant growth and production.

Shoot length of the subsequent growth flush following the treatments decreased with increasing rates of the growth retardants. The number of flower buds per plant increased with increasing rates of pacloburazol, chlormequat and daminozide. Prohexadione calcium was less effective in flower bud initiation and the worst results were obtained with trinexapac-ethyl.

Opis:

Popular in the urban environment is the horse chestnut, Aesculus hippocastanum which is suffering mainly due to the feeding of the horse chestnut leaf miner (Cameraria ohridella). The harmfulness of this pest is well recognized. Not much attention was put in discovering the interaction of this insect with the fungal pathogen Guignardia aesuli, the agent of leaf blotch. Host plant mediation in this particular insect-plant pathogen interaction is crucial for understanding the complexity of the horse chestnut’s current and future situation. Recognising the response of the host plant for separated and simultaneous colonisation by insect and fungus was the aim of this study. Leaf damage dynamics and phenolic compounds content (total soluble phenolic compounds – TPh, and condensed tannins – CT), and stem volume increment (SVI) of the horse chestnut saplings was considered and their relationship identified. The main hypothesis was that insect feeding and fungal infection when separated elicit a similar pattern in defence response of the host but this defence response is different when they both coexist on the same plant. Basing on crown projection area photographs sequence, foliage damage dynamics was assessed (Richard’s growth model) and protocol developed. Measurements of stem volume were performed sequentially to indicate potential growth response. Through this study, it was identified that the content of phenolic compounds in leaves was higher when both pests colonized saplings in comparison with those where saplings were infested by one biotic factor. It is also documented that foliage damage dynamics was higher when only the fungal pathogen attacked plants than when it was infected by both pests. A trade-off was identified between growth and secondary metabolism. Leaf damage affected stem volume increment only in the late summer, when a high level of defoliation was observed. Simultaneous infestation by fungal and insect agents made unfavourable conditions rather for the former. How this interaction affects the latter is not covered by our results and still remains undiscovered.

Opis:

The measurements have been performed in the nursery in the years 2007–2013 to study differences in size and correlations between selected growth factors in “knipboom” trees of 6 apple cultivars on M.9 rootstock. The trees of ‘Jonagold Decosta’ (‘Red Jonaprince’ in 2013) and ‘Fuji Beni Shogun’ showed the strongest growth, ‘Šampion’ and ‘Camspur’ the weakest one, whereas ‘Gala Must’ and ‘Golden Delicious Reinders’ were characterized by moderate vigor. Mean length of one feather increased from the tree top towards its base, but did not depend significantly on the number of laterals per tree. Correlations between growth factors were similar to those found in maiden apple trees and the closest ones were between total length of lateral shoots and their number on the tree. A trunk diameter had stronger correlations with other growth parameters than tree height.
Pomiarów dokonano w szkółce w latach 2007–2013 w celu zbadania różnic we wzroście i określenia korelacji pomiędzy wybranymi cechami wzrostowymi drzewek typu „knip boom” sześciu odmian jabłoni na podkładce M.9. Najsilniejszy wzrost wykazywały drzewka ‘Jonagold Decosta’ (‘Red Jonaprince’ w 2013) i ‘Fuji Beni Shogun’, natomiast najsłabszy ‘Šampion’ i ‘Camspur’, podczas gdy ‘Gala Must’ i ‘Golden Delicious Reinders’ charakteryzowały się średnią siłą wzrostu. Średnia długość pędu bocznego zwiększała się od szczytu drzewka do jego podstawy, lecz nie była istotnie zależna od liczby pędów bocznych. Korelacje pomiędzy cechami wzrostu były podobne do, tych jakie zaobserwowano w przypadku okulantów, przy czym najsilniejsza była zależność pomiędzy całkowitą długością pędów bocznych i ich liczbą na drzewie. Średnica pnia była silniej skorelowana z innymi cechami wzrostowymi, niż wysokość drzewek.

Opis:

The experiment was aimed at determining, whether exposure to static magnetic fields of intensities (1T,  2.5T, and 5T) stimulates the growth of Tosca bean seeds (Phaseolus vulgaris L.). Each treatment group in the  experiment underwent exposure to the magnetic field for a specific period of time, that is: 900s, 1800s, or  3600s. The measurements of root volumes were taken every 24 hours. The first measurement was taken after  96 hours since the beginning of germination. The collected data was analyzed using statistical methods.  The experiment allowed to determine that the magnetic field had a significant influence on the lowering of  bean seeds germination rate. The extent of this influence was dependent on the combination of factors: magnetic  field force- time of exposure.

Opis:

The present report illustrates an improved and reproducible micropropagation system for economically valuable bamboo species Pseudoxytenanthera stocksii using nodal segments. Direct organogenesis from nodal segments was accomplished by culturing on Murashige and Skoog (MS) medium supplemented with 6.0 mg/L 6-benzylaminopurine (BAP). On this medium combination 9.0±0.25 shoots per explant were induced. Shoot multiplication was subjective to the combination of auxins and cytokinins concentrations used and number of repeated transfer of mother explants or subculturing of in vitro regenerated shoot clumps on fresh medium. Maximum 41.9±1.00 shoots were observed on MS medium supplemented with 4.0 mg/L of BAP and 0.25 mg/L of naphthalene acetic acid (NAA). Half strength MS medium containing various concentrations of auxins was used for in vitro root formation. Successful rooting with maximum response was achieved on half strength MS medium + 50% sucrose and 1.0 mg/L IBA (24.3±0.27 roots). The rooted plantlets were planted the soilrite and hardened in the greenhouse for 6-8 weeks. Completely acclimatized plantlets exhibited 96% survivability. The present propagation protocol could satisfy the demand of P. stocksii and could be explored for the commercial propagation of this valuable manga bamboo.

Opis:

The aim of the experiment was to examine the effects of silicon (Si) on the growth and cropping of strawberry plants (Fragaria ananassa) and on the quality of the fruit. The study was conducted in 2013–2015 in the Experimental Orchard in Dąbrowice, belonging to the Research Institute of Horticulture in Skierniewice. The experimental objects were plants of the strawberry cultivars ‘Elkat’ and ‘Elsanta’, growing in a podsolic soil, low in humus, with the granulometric composition of light loam in the surface layer and with an average level of available nutrients. The experiment was designed in randomized blocks with three replications. An experimental plot was comprised of 20 strawberry plants planted at a spacing of 0.25 m × 1.0 m. The plants were treated with silicic acid, potassium silicate and calcium silicate. The preparations were applied annually to the soil in early spring (before the beginning of vegetation) at a dose of 90 kg Si per ha. Control plants were not treated with silicon. The results of the experiment were analysed statistically using the analysis of variance method. The differences between means were evaluated with Duncan’s test (p = 0.05). The results showed different responses of the tested strawberry cultivars to the silicon preparations used. In the case of ‘Elsanta’, the highest fruit yield was recorded in the plots where calcium silicate or potassium silicate were applied to the soil. It was also found that the use of potassium silicate, calcium silicate, and silicic acid reduced the occurrence of grey mould on the fruit of the cultivar ‘Elsanta’, but the differences as compared to the control were not statistically significant. The plants of the strawberry cultivar ‘Elkat’ treated with silicic acid produced the highest fruit yields, and the fruits were the least affected by grey mould. None of the silicon preparations affected the chlorophyll content of the leaves. It was also found that the use of the silicon preparations had no impact on the refractometric index of the fruits or their firmness. In both cultivars, the plants treated with silicic acid produced fruit with the highest Si content. The silicon content of the leaves of the tested strawberry cultivars was different for the individual years of the study. Depending on the year, the highest silicon content was found in the leaves of the plants treated with calcium silicate and silicic acid. Preparations containing silicon can be used in the commercial production of strawberry to reduce the occurrence of grey mould, but they cannot completely replace the chemical plant protection products designed for this purpose.

Opis:

Rice blast is one of the most destructive rice diseases known to cause considerable yield losses globally. Plant growth promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) are closely associated with rice plants and improve plant growth and health. To determine how isolated bacteria trigger rice growth, an assessment of phosphate solubilization and auxin production mechanisms was carried out in vitro and in vivo. In this study, the interactions between PGPR and Rhizophagus irregularis were evaluated in wildtype and CYCLOPS mutant plants to provide a sustainable solution against blast disease and reduce the amount of yield loss. Importantly, Bacillus subtilis UTSP40 and Pseudomonas fluorescens UTSP50 exhibited a suppressive effect on AMF colonization which shows the probable existence of a functional competition between AMF and PGPR to dominate the rhizosphere. On the other hand, R. irregularis decreased the biocontrol activity of B. subtilis UTSP40 in wild type, although this reduction was not significant in mutant plants. Results showed that the same defense-related genes were induced in the roots of wild type colonized by B. subtilis UTSP40 and R. irregularis. Therefore, plant cell programs may be shared during root colonization by these two groups of beneficial microorganisms.

Opis:

Asahi SL stimulates plant’s vital processes like growth and development, affects physiology and biochemistry, what often leads to increased biomass accumulation and yield. However, common is opinion that application of this preparation could be beneficial only, when treated plants are grown under unfavorable conditions. Therefore the aim of this work was the assessment of the stimulatory effect of Asahi SL on Arabidopsis thaliana L. and ornamental amaranth plants grown under optimal conditions. Plants treated with Asahi SL were higher and more advanced in development, particularly generative. Biomass accumulation was greater after biostimulator application mainly due to better photosynthetic apparatus efficiency, which was manifested by (i) greater leaf area, (ii) higher total chlorophyll content and (iii) increased intensity of photosynthesis. Effect of Asahi SL on chlorophyll a fluorescence was marginal. Despite of higher transpiration and lowered stomatal resistance the RWC was almost unchanged in biostimulator treated plants what was attributed to increased water uptake. Obtained results clearly showed that Asahi SL applied on plants can also be effective and beneficial when they are grown under optimal conditions.
Asahi SL stymuluje procesy życiowe roślin, jak również wzrost i rozwój oraz wpływa ma procesy fizjologiczne i biochemiczne, co często prowadzi do zwiększenia wytwarzanej biomasy i plonowania. Powszechną jest jednak opinia, że pozytywny wpływ preparatu ma miejsce, tylko wtedy, gdy rośliny rosną w niekorzystnych warunkach. Celem pracy były ocena stymulującego wpływu Asahi SL na rośliny rzodkiewnika pospolitego oraz szarłatu ozdobnego rosnące w warunkach optymalnych. Rośliny traktowane Asahi SL były, wyższe oraz bardziej zaawansowane w rozwoju, szczególnie generatywnym. Preparat podwyższał akumulację biomasy głównie poprzez poprawę sprawności aparatu fotosyntetycznego, która przejawiała się zwiększeniem (i) powierzchni liści, (ii) zawartości chlorofilu oraz (iii) intensywności fotosyntezy. Preparat miał niewielki wpływ na mierzone parametry fluorescencji chlorofilu a. Mimo wyższej transpiracji i obniżonych oporów dyfuzyjnych, u roślin traktowanych preparatem, ich RWC się nie zmieniło, co tłumaczyć można zwiększonym pobieraniem wody z podłoża. Uzyskane w tych badaniach wyniki dowodzą, że Asahi SL działa pozytywnie także na rośliny rosnące w warunkach optymalnych.

Opis:

The consequent effect of growth retardants: paclobutrazol – 0.1, 0.5, 1, 5 mg l⁻¹, flurprimidol – 0.1, 1, 5 mg l⁻¹, chlorocholine chloride (CCC) – 5, 50 mg l⁻¹ on the growth and development of Tibouchina urvilleana Cogn. in vitro was examined. Paclobutrazol at concentration of 1 or 5 mg l⁻¹ and flurprimidol at 5 mg l⁻¹ inhibited the growth of shoots significantly. It was noted that shoots originating from these media had thicker, straighter stems and shorter internodes. The stimulating influence of CCC at 5 mg l⁻¹ on the elongation of the main shoot was observed. Axillary shoots formation was the best when shoots were derived from the medium supplemented with flurprimidol 1 mg l⁻¹. Paclobutrazol at 0.5 and 1 mg l⁻¹ and flurprimidol at 5 mg l⁻¹ influenced the formation and fresh weight of roots increase, but flurprimidol was more effective. Growth retardants (except paclobutrazol at 5 mg l⁻¹) applied in the earlier passage stimulated elongation of roots.
Badano następczy wpływ następujących retardantów: paklobutrazolu – 0,1; 0,5; 1; 5 mg l⁻¹, fluropirimidolu – 0,1; 1; 5 mg l⁻¹, chlorku chlorocholiny (CCC) – 5, 50 mg l⁻¹ na wzrost i rozwój pędów Tibouchina urvilleana Cogn. in vitro. Paklobutrazol w stężeniu 1 i 5 mg l⁻¹, a także fluropirimidol w stężeniu 5 mg l⁻¹ istotnie hamowały wzrost pędów. Pędy pochodzące z tych pożywek były grubsze oraz sztywniejsze i miały krótsze międzywęźla. Obserwowano stymulujący wpływ CCC w stężeniu 5 mg l⁻¹ na wzrost elongacyjny pędu głównego. Największą liczbę pędów kątowych wytworzyły pędy inkubowane wcześniej na pożywce zawierającej 1 mg l⁻¹ fluropirimidolu. Paklobutrazol w stężeniu 0,5 i 1 mg l⁻¹ oraz fluropirimidol w ilości 5 mg l⁻¹ wpływały na regenerację i przyrost świeżej masy korzeni. Fluropirimidol wywierał silniejsze działanie. Retardanty (z wyjątkiem paklobutrazolu w stężeniu 5 mg l⁻¹) zastosowane we wcześniejszym pasażu stymulowały wzrost elongacyjny korzeni.

Opis:

The time-irreversible cell enlargement of plant cells at a constant temperature results from two independent physical processes, e.g. water absorption and cell wall yielding. In such a model cell growth starts with reduction in wall stress because of irreversible extension of the wall. The water absorption and physical expansion are spontaneous consequences of this initial modification of the cell wall (the juvenile cell vacuolate, takes up water and expands). In this model the irreversible aspect of growth arises from the extension of the cell wall. Such theory expressed quantitatively by time-dependent growth equation was elaborated by Lockhart in the 60's.The growth equation omit however a very important factor, namely the environmental temperature at which the plant cells grow. In this paper we put forward a simple phenomenological model which introduces into the growth equation the notion of temperature. Moreover, we introduce into the modified growth equation the possible influence of external growth stimulator or inhibitor (phytohormones or abiotic factors). In the presence of such external perturbations two possible theoretical solutions have been found: the linear reaction to the application of growth hormones/abiotic factors and the non-linear one. Both solutions reflect and predict two different experimental conditions, respectively (growth at constant or increasing concentration of stimulator/inhibitor). The non-linear solution reflects a common situation interesting from an environmental pollution point of view e.g. the influence of increasing (with time) concentration of toxins on plant growth. Having obtained temperature modified growth equations we can draw further qualitative and, especially, quantitative conclusions about the mechanical properties of the cell wall itself. This also concerns a new and interesting result obtained in our model: We have calculated the magnitude of the cell wall yielding coefficient (T) [m3 J-1•s-1] in function of temperature which has acquired reasonable numerical value throughout.

Opis:

Bakterie promujące wzrost roślin (PGPB) to wolno żyjące organizmy glebowe, które mogą bezpośrednio lub pośrednio ułatwiać wzrost roślin w biotycznych lub abiotycznych warunkach stresowych. Mogą także produkować fitohormony i syntezować związki lub enzymy, które mogą modulować wzrost i rozwój (Glick et al. 2007). Pośrednie promowanie wzrostu roślin obejmuje wiele mechanizmów, dzięki którym bakterie mogą ograniczać rozwój patogenów roślinnych. Korzystny wpływ na wzrost roślin zmienia się znacznie w zależności od indywidualnych szczepów bakteryjnych oraz warunków wzrostu. Ważnym zjawiskiem jest produkcja antybiotyków przez bakteryjne endofity roślinne, w szczególności obserwowane u licznych gatunków Pseudomonas. Substancje te skutecznie ograniczają wzrost patogenów roślinnych (Klama, 2004). Celem badań było wyizolowanie bakterii strefy korzeniowej i ocena inhibicji wzrostu grzybów będących patogenami roślin wobec wyizolowanych szczepów bakteryjnych. W przeprowadzonych badaniach wykorzystano rośliny (Festuca rubra, Morus alba, Arabidopsis thaliana) rosnące w pobliżu huty cynku w Miasteczku Śląskim na glebie zanieczyszczonej metalami ciężkimi i nawożonej komunalnymi osadami ściekowymi. Bakterie izolowano z korzeni roślin stosując trzy długości czasu dezynfekcji (0, 2.5, 10 min). Po uzyskaniu czystych kultur bakteryjnych prowadzono testy zahamowania wzrostu w warunkach in vitro wobec czterech szczepów grzybów: FO – Fusarium oxysporum, FC – F. culmorum, AA1 – Alternaria alternata 1, AA2 – A. alternata 2. Wyniki eksperymentu wskazują, że bakterie izolowane po czasie 2.5 i 10 minut sterylizacji, czyli głównie bakterie endofityczne, hamowały rozwój badanych grzybów – potencjalnych patogenów roślin. Badania wykazały także, że z rzodkiewnika pospolitego (Arabidopsis thaliana), znanego halofita, pozyskano najwyższą liczbę mikroorganizmów, które także wykazywały najlepsze właściwości inhibitujące wzrost grzybni wszystkich badanych patogenów.
The main purpose of this study was to evaluate impact of plant growth promoting bacteria (PGPB) on the development of phytopathogenic fungi and correlate it with a potential effects on the growth of plants under unfavorable conditions, in order to improve the efficiency of a phytoremediation process. The conducted research focused on the antifungal properties of PGPB. In this study, 51 isolates of bacteria were obtained after diversified disinfection time from plants growing on soil after sewage sludge amendment. The results revealed that some isolated bacteria, mainly endophytic ones, inhibited the development of Fusarium oxysporum, F. culmorum and Alternaria alternata.

Opis:

Rare and endemic plant species represent important components of plant biodiversity which require protection to ensure their sustainable conservation. Cerastium banaticum (Rochel) Heuff. is such an endemic and rare species from Romania, for which the genetic variability of two natural populations was studied by SSR markers. Shannon’s information index revealed low levels of genetic diversity in both populations (I = 0.296). As the first attempt in a conservation program a reproducible micropropagation protocol was established starting from seeds, followed by multiplication, rooting, and ex vitro acclimatization. Among the various plant growth regulators tested the highest multiplication coefficient was achieved on a culture medium with 0.5 mg L -1 6-furfurylaminopurine (K) and 1 mg L -1 α-naphthaleneacetic acid (NAA). On this PGRs concentration a number of 26.6 shoots/individual explant with a mean length of 7.9 cm for new generated shoots was registered. The highest number of roots/indi- vidual initiated shoot was 2.6 and it was recorded on a culture medium with 0.5 mg L -1 2-isopentyl-adenine (2iP) and 0.1 mg L -1 NAA.

Opis:

Solanaceae plants have strong allelopathic potential, and therefore the action is confirmed through: a) bioassays with liquid or various solvent extracts and residues, b) fractionation, identification, and quantification of causative allelochemicals. Most assessments of allelopathy involve bioassays of plant or soil extracts, leachates, fractions, and residues which support seed germination and seedling growth in laboratory and greenhouse experiments. Plant growth is also stimulated below the allelopathic threshold, however severe growth reductions may be observed above the threshold concentration depending on the sensitivity of the receiving species. Generally, seedling growth is more sensitive than germination, particularly root growth. Some approaches showed that field soil collected beneath donor plants significantly reduced or somewhat promoted the growth of the recipients plants. Petri dish bioassays with aqueous extracts of different parts of donor plants showed considerable phytotoxic activities in a concentration-dependent manner with leaf aqueous extracts being most dominant. Delayed seed germination and slow root growth attributable to the extracts may be baffled with diffusion effects on the rate of imbibition, delayed initiation of germination, and particularly cell elongation; the main factor that is responsible for affecting root growth before and after the tip penetrates the testa. Light and electron microscopy extract analysis at the ultrastructural level are correctly investigated. Several Solanaceae plants have allelopathic potential, and therefore the activities, kinds and quantity of allelopathic compounds differ depending on the plant species. The incorporation of allelopathic substances into agricultural management might scale back the development of pesticides and reduce environmental deterioration.

Opis:

Although the uses of plant growth stimulating bacteria (PGPR) to improve the yield of graminaceous crops have been studied for over seventy years the utility of the technology remains uncertain. Increases in crop yield have often been inconsistent, reflecting a lack of understanding of the mechanisms by which PGPR exert their effects. Because PGPR are able to fix N2, this was initially assumed to boost crops by supplementing soil N. However, it is now clear, that for most free living PGPR, other mechanisms affecting root development, and nutrient uptake can account for the observed increase in crop yields. Here we review the current state of our understanding of PGPR in graminaceous crop cultivation, identifying their potential contribution to more sustainable agricultural practices but also highlighting issues that need to be addressed before this technology can be appropriately assessed as a replacement for inorganic N addition.

Opis:

Tomato and pepper are some of the most important and widely grown vegetable crops in the world. Like many other vegetables and fruits, tomato and pepper are threatened by biotic and abiotic stresses. Conventional agricultural practices frequently rely on synthetic fertilizers and pesticides that have adverse effects on humans, animals and environments. In this situation, the use of Plant Growth Promoting Rhizobacteria (PGPR) can better crop yield, as these are vital components of soil fertility and plant growth promotion, moreover, they can display antagonistic effects against phytopathogens. Under such circumstances, knowledge about the local bacterial populations, their identification, and their implications for improving management practices (vis-a-vis plant growth promotion and destruction of plant diseases) is very important. Recent advances in microbial and molecular techniques have significantly contributed to introducing many different bacterial genera into soils, onto seeds, roots, tubers or other planting materials to control disease and improve productivity. Plant growth promoting rhizobacteria have been generally applied to high value crops like tomato and pepper. Thus, this review is intended to summaries the literature on plant growth promoting rhizobacteria for growth promotion potential and biocontrol agent against tomato and pepper disease.

Chromium is a heavy metal; this element is considered as an environmental hazard. Toxicity effects of chromium on growth and development of plants including inhibition of germination process decrease of growth and biomass of plant. The aim of this research is to study accumulation of Chromium along with nutrients and its effect on the growth of Paddy plant (Oryza sativa L). Thus, paddy seedlings grown in petriplates lined with filter paper undergoing, different treatments of Cr (0, 2.5, 5, 10, 25, 50, 75, 100 and 200 mg/L). After one week seedlings were removed and morpho physiological parameters like root length, shoot length and dry weight of plants and Biochemicals ,accumulation of nutrients along with Cr in roots and shoots were determined. The results indicated that the concentrations more than 100 mg/L chromium cause the reduction of morphophysiology parameters in the treatment plants rather than control plant and Cr addition in the cultures caused enhancement of chromium content in roots and shoots of plant seedlings. Similarly the biochemicals and nutrient accumulation also affected by increasing concentrations of chromium. It was also noted that accumulation of chromium in the roots was much higher than the shoots of the seedlings under treatment.

Opis:

The objective of this study was to explore the possible improvement of plant growth using the activity of the bacterial enzyme ACC (1-aminocyclopropane-1-carboxylate) deaminase (endophytes and rhizobacteria). The beneficial effect of ACC deaminase activity was tested on the plants growing under stress conditions (high concentrations of heavy metals: cadmium, lead, zinc in the soil). The bacteria were isolated from three plants species: Festuca rubra L., Agrostis capillaris L., Arabidopsis thaliana L. Heynh, acquired from the area contaminated with heavy metals. The strains with the highest ACC deaminase activity were used to prepare a bacterial consortium and inoculate the plants. It has been shown that inoculation of plants with ACC producing bacteria has a positive effect on their growth under stress conditions. The bacterial entophytes strains showed a higher activity of ACC deaminase, which resulted in a higher biomass growth of inoculated plants. The PGPB bacteria may limit the toxicity of harmful ions and thus the increase the adaptive properties of plants. Moreover, it was discovered that the bacteria mainly belonging to genus Bacillus and Pseudomonas had the highest ACC deaminase activity in the environment contaminated with multiple heavy metals. The use of selected microorganisms and plants will provide results in an increasing efficiency of phytoremediation.

Opis:

This publication contains a short description of the immobilization process. The advantages and disadvantages of immobilizing biological factors have been mentioned. The carriers used (mainly sodium alginate) have been described. Techniques used to carry out immobilization (using a carrier or not) are presented. Also discussed is a prototype microcapsule production plant that can be used in many industries, including food, cosmetics and pharmaceutical. Produced microcapsules, depending on the factors subjected to immobilization (chemical substances or microorganisms), can be used in bioremediation or in supporting plant growth. Due to the use of microcapsules, the immobilized medium is separated from the reaction medium. In the case of microorganisms, this results in an increase in their lifetime because fluctuations of some process parameters (eg temperature, pH, nutrient composition) do not affect them directly. Immobilized microorganisms, such as PGPR bacteria, can stimulate plant growth through the production of phytohormones, fight against pathogens and induce their systemic immunity. While, the use of microcapsules, with immobilized microorganisms, in bioaugmentation processes will allow them to provide optimal development conditions and extend their lifespan, thus extending their duration. The costs incurred will decrease because the number of repetitions will be reduced. The interest in using microcapsules in biotechnological processes, and not only, is increasing. They become an alternative to traditional techniques.
Celem publikacji jest dokonanie charakterystyki przemysłowego procesu immobilizacji substancji aktywnych przeznaczonych do użytku środowiskowego (bioremediacja, rolnictwo). W pracy omówiono wady i zalety unieruchomienia czynników biologicznych. Opisano także stosowane nośniki (głównie jest to alginian sodu) oraz przedstawiono techniki stosowane do przeprowadzenia immobilizacji (z wykorzystaniem nośnika). Omówiono również prototypową instalację do wytwarzania mikrokapsułek, które mogą być stosowane w wielu gałęziach przemysłu, m.in. spożywczym, kosmetycznym, farmaceutycznym. Wyprodukowane mikrokapsułki, w zależności od czynników poddanych immobilizacji (substancje chemiczne lub mikroorganizmy), mogą być stosowane w bioremediacji lub we wspomaganiu wzrostu roślin. Dzięki zastosowaniu mikrokapsułek immobilizowany czynnik oddzielony jest od środowiska reakcji. W przypadku mikroorganizmów skutkuje to wydłużeniem ich żywotności, ponieważ wahania niektórych parametrów procesu (np. temperatura, pH, skład pożywki) nie wpływają na nie bezpośrednio. Immobilizowane mikroorganizmy, takie jak bakterie PGPR, mogą stymulować wzrost roślin poprzez produkcję fitohormonów, zwalczanie patogenów oraz indukcję ich odporności systemicznej. Natomiast wykorzystanie mikrokapsułek z unieruchomionymi mikroorganizmami w procesach bioaugmentacji pozwoli na zapewnienie im optymalnych warunków rozwoju oraz wydłużenie ich żywotności, a poprzez to wydłuży czas ich działania. Zainteresowanie wykorzystaniem mikrokapsułek alginianowych w procesach biotechnologicznych zwiększa się; stają się one alternatywą dla tradycyjnych technik immobilizacji.

The results of the assessment of morphological traits of plants (growth vigor and shrub habit), yielding and fruit weight of seven Saskatoon berry (Amelanchier alnifolia Nutt.) genotypes are presented in the paper. The research was conducted in 2017–2018. The cultivar trail experiment was established in 2011 in the field of the Experimental Orchard of the Research Institute of Horticulture – in Dąbrowice, near Skierniewice (central Poland). Four Canadian cultivars (‘Martin’, ‘Pembina’, ‘Smoky’ and ‘Thiessen’) and three breeding clones of the Research Institute of Horticulture (clone 5/6, type N and type S) were assessed. The results of the studies showed that the shrubs of the clone 5/6 produced the tallest plants and grew the strongest. The shrubs of the cultivar ‘Pembina’, which produced short and narrow plants, grew the weakest. The shrubs of the breeding clone 5/6 had the most erect habit. The highest fruit yields were given by shrubs of clones type S and type N, and the lowest – by ‘Pembina’. The cultivar ‘Martin’ had the largest fruit, the smallest – ‘Pembina’ and clone 5/6. The results obtained in 2017–2018 largely confirmed the results obtained in the years 2015–2016.

Opis:

Mulberry (Morus alba L.) is an ornamental, medicinal, and fruit plant that belongs to the Moraceae family. One of the most important techniques used in plant biotechnology is tissue culture, which enables mass production of pathogen-free plants. Cotyledon has a high potential for shoot regeneration; however, to the best of our knowledge, there are no reports on plant regeneration from cotyledon explants of mulberry. Therefore, this study aimed to evaluate the potential of seedling-derived cotyledon segments to obtain shoot multiplication of mulberry. Various concentrations (0, 0.25, 0.5, 1, 2, 3, and 4 mg/l) of thidiazuron (TDZ) in combination with indole butyric acid (IBA) were used in a completely randomized design in three replications. The results showed that the highest percentage of regeneration frequency (96.67%) and the maximum number of shoots (4.43) were obtained on Murashige and Skoog (MS) medium supplemented with 0.25 mg/l TDZ and 0.025 mg/l IBA. In the rooting experiment, the maximum rooting percentage (83.33%) and the maximum number of roots per shoot (4.36) were obtained on MS medium containing 2 mg/l IBA. In vitro-raised plantlets were placed in pots and kept in room temperature for 30 days, and the plantlets showed more than 90% survival rate. On the basis of our results, the protocol described in this study has a high potential to be used in the micropropagation of this valuable plant.

The aim of the study was to determine the effect of various biopreparations on the growth of the apple root system, the number of spores of AMF, the total number of bacteria and microscopic fungi in the rhizosphere soil, and the degree of mycorrhizal association in the roots of two apple tree cultivars. The experiment was established in the spring of 2009 in the Experimental Orchard of the Institute of Horticulture in Dąbrowice. The research objects were one-year-old maidens of the apple cultivars ‘Topaz’ and ‘Ariva’ grafted on M26 rootstock. The trees were treated with the following biopreparations: control, control NPK (standard NPK fertilization), manure, Micosat F + manure, Humus UP, Humus Active + Aktywit PM, BioFeed Amin + manure, BioFeed Quality + manure, Tytanit + manure, Vinassa + manure, Florovit Eko, and Florovit Pro Natura. Treatment of ‘Topaz’ and ‘Ariva’ apple trees with the biopreparations Micosat F, Humus UP, Humus Active + Aktywit PM, BioFeed Amin, Vinassa, Florovit Eko and Florovit Pro Natura produced positive effects on the growth of apple roots and their mycorrhizal frequency, and the size of the populations of microorganisms in the rhizosphere soil.

Opis:

Salinity occurring in intensively used agricultural, industrialized, and urbanized areas is one of the main factors in soil degradation. The effect of silver nanoparticles (AgNPs) on plant growth under environmental stresses is still not fully understood. Two experiments were conducted on the response of Asiatic lilies to treatment with colloidal AgNPs. In Experiment I, the study aimed to evaluate the effect of treating 'Osasco' lily bulbs with colloidal AgNPs (0, 25, 50, 100, and 150 ppm) on growth, flowering, and bulb yield, as well as the production of bulblets. Compared with the control, the applied colloidal AgNPs at all concentrations caused an acceleration of flowering and an increase in bulb diameter and the fresh weight of the aboveground part of the plants and bulbs. In addition, treatment with colloidal AgNPs at concentrations of 100 and 150 ppm increased bulblets’ number and fresh weight. In Experiment II, the effects of colloidal AgNPs (100 ppm) and NaCl stress (600 mM) on the growth parameters, assimilation pigment content, and chemical composition of 'Bright Pixi' lily leaves were evaluated. As a result of the application of colloidal AgNPs, plants flowered faster and had increased height, petal width, fresh bulb weight, bulb diameter, and several scales in the bulb. Under NaCl stress, plants had reduced fresh weight of the aboveground part and bulb, bulb diameter, number of scales in a bulb, and contents of assimilation pigments, N, K, Ca, Cu, Mn and Zn. Colloidal AgNPs offset the adverse effects of salinity on bulb yield by increasing fresh bulb, bulb diameter, and the number of scales in lily bulbs. In conclusion, using colloidal AgNPs can contribute to developing new methods of bulbous plants production and an effective strategy to protect plants from ever-increasing land salinization.

The role of the tea commodity in the economy of Indonesia is quite strategic. Various types of microorganisms in nature have been known to increase the benefit of the root function, suppress disease, and accelerate plant growth. This study aimed to determine the potential of indigenous bacteria (Azoto II-1, Acinetobacter sp., bacteria Endo-5, bacteria Endo-65 and Endo-76) on the growth of tea plants and their potential in increasing resistance to blister blight disease. The test of microbes’ potential effect on growth and blister blight was conducted in Gambung, West Java in an experimental field using a randomized block design (RBD) with six treatments and each treatment was replicated four times. The composition of the treatments was: A) Endo-5; B) Endo-65; C) Endo-76; D) Azoto II-1; E) Acinetobacter sp.; and F) control (without microbes). Bacterial suspension was applied directly to the soil at a dose of 2 l · ha−1. The bacterial suspension was applied six times at 1 week intervals. The results of field observations indicated that the intensity of blister blight decreased in all treatments but did not significantly differ from the control. Meanwhile, the results of Acinetobacter sp. treatment in tea shoots was 17.26% higher than the control.

Opis:

Wheat and corn crops contribute to the food security of humans by providing a nutrient-rich diet. However, their production in abiotic stress conditions such as salinity is limited. Endophytes exert a beneficial effect on plants through the decomposition of organic materials for smooth absorption, detoxification, and reduction of the effect of phytopathogenic microorganisms by increasing the immunity of host plants to resist phytopathogens and through nutrient deposition in plants responsible for reducing salt stress. The present study aimed to evaluate the NaCl tolerance efficiency of Triticum aestivum L. var. HD 2687 and Zea mays var. PSCL-4642 cultivars at the germination stage after inoculation with salt-tolerant bacterial endophyte BoGl21 isolated from Bougainvillea glabra. The seeds of both crops were tested for percentage of seed germination with/without bacteria at 50, 100, 150, and 200 mM NaCl concentrations. The BoGl21 isolate induced a significant increase in radicle length in corn (25.6 mm) as compared to that in wheat (10.3 mm) at 50 mM NaCl. However, at 100 mM NaCl, the radical length of wheat and corn seedlings was 5 mm and 8.8 mm, respectively. Inoculation of maize and wheat with the bacterial isolate significantly increased the plumule length of the germinated seeds as compared to that of controls. BoGl21 increased the plumule length of wheat as compared to that of the control seeds by 31.9, 11.7, and 4.8 mm at 50, 100, and 150 mM salinity stress, respectively. Inoculation of corn seeds with BoGl21 at the tested NaCl levels (50, 100, and 150 mM NaCl) increased the plumule length of the germinated seeds by 33.1, 22, 13.2, and 3.2 mm, respectively. The current research results support the hypothesis that bacterial endophytes could be beneficial to minimize the toxicity of saline stress on wheat and corn at the time of germination.

Opis:

The current study aimed to evaluate the effect of banana waste biochar on the physiological traits and growth of Paspalum vaginatum under three water treatments (100%, 80%, and 60% of the water holding capacity (WHC) of the soil). A plastic pot experiment was done for the germination of paspalum vaginatum. The treatments were the addition of compost, banana waste biochar, or banana waste biochar and compost combination to the soil. We used multiple factor analysis (MFA) to reveal the relationship between the effect of banana waste biochar and the three water regimes on physiological data. The findings revealed that banana waste biochar had an important impacts on all traits under various water supply conditions. The photon yield of PSII of control treatment at three water regimes had the lowest response compared to amended treatments. Changes were observed in chlorophyll pigment among different treatments.

Opis:

The purpose of the studies was to determine the effects of Stymjod, a growth regulator, on blue fescue (Festuca glauca) development and morphological characteristics. The experiment was an attempt to determine the effect of different concentrations of Stymjod on the leaf greenness index, the number and length of leaf blades, the length of roots, and the dry weight of roots and leaves. The plant used in the experiment, Festuca glauca, was grown in pots. The following three treatment combinations were used: spraying plants with distilled water only; with Stymjod at a concentration of 2% in the spraying fluid; with Stymjod at a concentration of 4%. Spraying was carried out four times at weekly intervals. It was found that the 2% concentration of Stymjod in the solution significantly improved most morphological. Festuca glauca treated with Stymjod was characterized by better efficiency of the photosynthetic apparatus and photosynthetic activity.

Opis:

The experiment was carried out in 2007-2009, in the central-eastern Poland. The investigated factors were kind of covers: the control without covering, perforated foil with 100 holes per 1m2 and polypropylene fibre weighing 17·g·m-2, and broad beans cultivars - ‘White Windsor’, ‘Bizon’ and ‘Bachus’. Broad bean seeds were sown at the beginning of the second decade of April, at 50 × 10 cm spacing. Directly after sowing the field was covered by covers, which were left on the plants for 3 weeks. After removing the covers the height of plants was measured. Broad bean was harvested at the stage of milk maturity of seeds. The height of broad bean plants and the number of pods per plant were determined prior to the harvest. During the harvest the weight of pods and the yield of fresh seeds were determined and productivity of seeds was calculated from the weight of pods. Biometric parameters of pods and seeds i.e. length of pods, the number of seeds per pod and length, width and thickness of seeds were measured. It was found that the broad bean covering contributed to increase in the height of plant and yield as well as improvement of the biometric parameters of pods and seeds compared to the control object without covering. The highest yield of pods and seeds was produced by ‘Bizon’ cv. Plants covered by polypropylene fibre yielded best. The seeds of grown cultivars were characterized by similar parameters. Polypropylene fibre covering favoured formation of pods and seeds in the pods but did not cause changes in the seed parameters.

Opis:

In ash internodes isolated from vertical stems during winter dormancy, cambial activity was stimulated by applying an aqueous solution of auxin to the apical end and water to the basal end. The internodes maintained nearly horizontally produced cambial callus at the apical cut surface with more callus on the upper half although both halves were in contact with the same concentration of auxin. A differential response to auxin of the cambium in the upper and lower halves of the horizontally oriented internodes is postulated.

Opis:

The studies conducted in the years 2004–2006 in a production orchard in the habitat conditions of the Sandomierska Upland showed that the trees budded on the seedlings of wild cherry grew more strongly than on Colt rootstock. No significant differences were observed between the rootstocks as for the trunk thickness and the crown size of young trees planted in 2001. In the group of trees planted in 1996, which were in the period of full fruiting, the crowns of trees budded on wild cherry were significantly bigger than on Colt rootstock. No significant differences were found out in the yielding of trees on wild cherry and Colt rootstock. Considerable differences in the yielding between the studied years in the group of young trees with systematic increasion was effected by increase of crown. ‘Kordia’ cv. is a valuable cultivar for Sandomierska Upland. It begins late the fruiting period (the first commercial yield in the fifth year after planting); however, it gives attractive fruits and high productivity of trees.
Badania wykonane w latach 2004–2006 w sadzie produkcyjnym w warunkach siedliskowych Wyżyny Sandomierskiej wykazały, że drzewa okulizowane na siewkach czereśni ptasiej rosły silniej niż na podkładce Colt. Nie wykazano istotnych różnic między podkładkami dla grubości pni i objętości koron drzew młodych sadzonych w 2001 r. W grupie drzew sadzonych w 1996 r., będących w pełni owocowania korony drzew okulizowanych na czereśni ptasiej były istotnie większe niż na podkładce Colt. W badanych warunkach nie wykazano istotnych różnic plonowania drzew na czereśni ptasiej i podkładce Colt. Odmiana ‘Kordia’ jest bardzo wartościową odmianą do nasadzeń produkcyjnych na Wyżynie Sandomierskiej. Wchodzi ona dosyć późno w okres owocowania (pierwszy plon handlowy w 5 roku po posadzeniu), daje jednak atrakcyjne owoce, odporne na pękanie na deszczu. Odmiana ‘Kordia’ plonowała obficie na obydwu badanych podkładkach, wykazując wysoką produktywność drzew.

Opis:

Primula veris L. (Primulaceae) is a well-known medicinal herb. The callus induction response of three explant types: roots, cotyledons, and hypocotyls of four-week-old cowslip seedlings were evaluated. The highest statistically different callus induction rate was 93.6% and was obtained from root explants on MS medium supplemented with 0.1 mg/l BA and 5.0 mg/l PIC. Calli also appeared on 83.3% of cotyledon explants on MS medium supplemented with 1.0 mg/l BA and 3.5 mg/l 2,4-D and on 81.0% of root explants on MS medium supplemented with 0.1 mg/l KIN and 2.0 mg/l 2,4-D. These values were not statistically different. The average time required for callus initiation was 4 to 6 weeks, however, it depended on the explants type. The most suitable condition for callus proliferation and growth was MS medium with 0.5 mg/l TDZ and 0.1 mg/l NAA, and with 1.0 mg/l BA and 2.0 mg/l or 3.5 mg/l 2,4-D. No light conditions proved to be more favourable for cowslip calli induction and growth.

Najwyższy, istotny statystycznie i wynoszący 93,6% indukcji tkanki kalusowej uzyskano z eksplantatów korzeniowych na podłożu Murashige i Skooga (MS) zawierającego 0,1 mg/l BA i 5,0 mg/l PIC. Indukcję kalusa obserwowano także na 83,3% eksplantatów liścieniowych na pożywce MS uzupełnionej 1,0 mg/l BA i 3,5 mg/l 2,4-D oraz na 81,0% eksplantatów korzeniowych na pożywce MS zawierającej 0,1 mg/l KIN i 2,0 mg/l 2,4-D. Średni czas potrzebny do inicjacji kalusa wyniósł 4 do 6 tygodni i zależał od rodzaju eksplantatu. Podłoża MS uzupełnione 0,5 mg/l TDZ i 0,1 mg/l NAA oraz 1,0 mg/l BA i 2,0 mg/l lub 3,5 mg/l 2,4-D okazały się najodpowiedniejszymi dla dalszego rozwoju i wzrostu zregenerowanej tkanki kalusowej. Warunki bez dostępu światła były korzystniejsze dla indukcji i wzrostu tkanki kalusowej pierwiosnka lekarskiego.

The effects of different growing media on development of above and under ground parts of plant were statistically significant. The highest number of primary roots per plant, length of the most developed roots and number of crowns per runner were obtained from perlite, finpeat+perlite and peat medium, respectively, in both cultivars. The runner length, number of runners per plant, leaf area, fresh root weight and dry root weight varied between cultivars according to growth medium. In general peat, finpeat or finpeat+perlite gave the best results in terms of above and under ground parts of plants in both cultivars. Some important properties such as water retention capacity, cation exchangeable capacity, pH, porosity etc. of growing media using in this study were also determined.

Opis:

In the experiment, carried out between 2005–2007, the influence of the application of two rootstocks and mycorrhizal vaccine on the growth of maiden trees and the trees of ‘Woodii’ cultivar in the third year after planting them into the ground was compared. A higher percentage of maiden trees was obtained on Prunus tomentosa rootstock when mycorrhizal vaccine was applied as well. The applied rootstocks did not differ the growth of maiden trees in a nursery. Also the use of mycorrhizal vaccine did not cause any significantly stronger growth of maiden trees on both rootstocks, what is more they even reduced the sum of the lengths of lateral shoots. The reaction of rootstocks was differentiated. The considered rootstocks, however, influenced all the parameters of growth of trees in the third year after planting. Stronger growth of ‘Woodii’ cultivar trees was observed on the Prunus cerasifera rootstock compared with those growing on Prunus tomentosa. However, the trees growing on the Prunus cerasifera rootstock bloomed poorer than those on Prunus tomentosa. Application of mycorrhizal vaccine increased the thickness of the tree trunk and the diameter of crowns of ‘Woodii’ cultivar trees, but it did not influence their flowering and fruiting.
W doświadczeniu przeprowadzonym w latach 2005–2007 porównano wpływ dwóch podkładek i zastosowanie szczepionki mikoryzowej na wzrost okulantów i drzew odmiany ‘Woodii’ w trzecim roku po posadzeniu. Wyższy procent okulantów otrzymano na podkładce Prunus tomentosa oraz przy zastosowaniu szczepionki mikoryzowej. Podkładki nie zróżnicowały wzrostu okulantów w szkółce. Zastosowanie szczepionki mikoryzowej nie spowodowało silniejszego wzrostu okulantów na obu podkładkach, a nawet zredukowało istotnie sumę długości pędów bocznych. Reakcja podkładek była zróżnicowana. Rozpatrywane podkładki wpłynęły na wszystkie paramerty wzrostu drzew w trzecim roku po posadzeniu. Silniej rosły drzewa odmiany ‘Woodii’ na podkładce Prunus cerasifera niż Prunus tomentosa. Drzewa na podkładce Prunus cerasifera słabiej jednak kwitły od tych na podkładce Prunus tomentosa. Zastosowanie szczepionki mikoryzowej zwiększyło grubość pnia i rozmiar koron drzew odmiany ‘Woodii’, a nie miało wpływu na ich kwitnienie i owocowanie.

In accordance with the National Program for Increasing Forest Cover it is planned to augment Poland’s forest cover to 30% by 2020. This task involves afforestation of agricultural lands by pioneer species that have low habitat requirements, such as the silver birch or the Scots pine. Application of sawdust, clear cutting residues, compost bark and compost beneath tree roots contributed to better development of the assimilation apparatus. The use of mineral fertilizer stimulated tree growth as well as improved physical and chemical properties of soil.

Opis:

Preparaty mikrobiologiczne niebędące środkiem ochrony roślin wykorzystują najczęściej zjawisko antagonizmu pomiędzy patogenem a stosowanym organizmem pożytecznym. Produkty te często są zaliczane do grupy stymulatorów wzrostu. Badania dotyczące stosowania EM i różnych metod ich stosowania zostały wykonane w latach 2011-2012 na plantacji truskawek odm. Honeoye. Efektywność zabiegów oceniano na podstawie uzyskanej świeżej masy części nadziemnych roślin, liczby rozłogów z wybranych 10 roślin z każdego poletka oraz plonowania. Oceniano także zawartość chlorofilu, gdyż ilościowa i jakościowa analiza chlorofili w roślinach traktowanych EM może być wskaźnikiem dostępności dla nich składników pokarmowych. Po zastosowaniu EM w 5% koncentracji zdecydowanie wzrosła masa części nadziemnych roślin truskawki, które 6-krotnie traktowano nalistnie. Zwiększenie koncentracji do 10% nie spowodowało polepszenia parametrów wzrostu roślin, ani zwiększenia liczby rozłogów. Stosowanie zabiegów z większą częstotliwością nie wpłynęło na polepszenie rozwoju roślin. Podobne tendencje obserwowano dla plonowania. Nie obserwowano wpływu EM zabiegów na zawartość chlorofilu.
Preparations based on micro-organisms may complement the currently known means of agricultural production. Microbial preparations usually use the phenomenon of antagonism between the pathogen and the beneficial organism. These preparations are often called as growth promoters. Investigations on the use of EM and different methods of their applications were conducted in 2011-2012 on strawberries cv. Honeoye. The effectiveness of treatments was evaluated on the basis of the fresh weight of the aerial parts of plants and the number of runners of the selected 10 plants from each plot and the yield. Chlorophyll was also evaluated as a quantitative and qualitative analysis of content in plants treated with EM. After 6 applications of EM increased of weight of strawberry aboveground parts was noted. Increasing the concentration to 10% did not result in improvement of the parameters of plant growth, or increase in the number of runners. The use of higher frequency of treatments did not affect the improvement of plant growth. Similar trends were observed for yield. There was no effect of EM treatment on the content of chlorophyll.

Opis:

Effects of 62 isolates (of 41 taxa) of fungi on growth of 1-year-old oak (Quercus robur) seedlings were studied in an inoculation experiment. The fungi were isolated from roots of 80–96-year-old Q. robur that had been subjected to periodic flooding and had symptoms of oak decline. The fungal genera included Alternaria, Aspergillus, Calonectria, Chaetomium, Cladosporium, Clonostachys, Corynespora, Cylindrocarpon, Dicyma, Geotrichum, Ilyonectria, Isaria, Metarhizium, Oidiodendron, Ophiostoma, Pezicula, Phialocephala, Phialophora, Pyrenochaeta, Sporendocladia, Sporothrix, Thelonectria, Trichoderma and Trimmatostroma. Mycelial colonies of fungi growing in potato-dextrose broth were used for soil inoculation. Plant growth was assessed 2 years after inoculation, when the plants were 3 years old. Stem lengths, and dry weights of stems, roots and leaves were measured. Stem growth was inhibited by 31 isolates (50%) and root growth by 12 isolates (19%). Stem growth was stimulated by two isolates (3%) and root growth by 17 isolates (27%). The overall ratio of inhibitors to stimulants was 2.1. The proportion of taxa that inhibited stem growth was 16 times greater than that which promoted stem growth. The proportion of taxa that promoted root growth was only 1.5 times greater than that which inhibited root growth. The structure of the fungal communities in periodically flooded oak forests suggests that they are more likely to inhibit than to promote vigour in oaks.
