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:
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.

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:
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.

In the literature there are no reports on methodpropagation of this shrub in in vitro cultures. Therefore, the aim of this study was a development of the method micropropagation of Calycanthus fertilis Walter. Shoot explants of the size 1 cm, with an apex or node with lateral meristems were placed on the media with mineral composition according to MS and WPM supplemented with BAP (from 0.5 to 2.0 mg·dm–3) and TDZ (from 0.1 to 0.5 mg·dm–3). BAP turnedout to significantly increase initiation frequency whereas TDZ inhibitedthe formation of adventitious shoots andcausedexplant death. The highest percentage of initiated explants were found in shoot fragments placed on WPM medium supplemented with 1.0 mg·dm–3 BAP. Primary explants which initiatedgrowth were transferredon the proliferation media containing WPM macroand microelement, with the addition of different cytokinin: BAP (from 0.5 to 2.5 mg·dm–3), KIN (1.0 to 5.0 mg·dm–3) or TDZ (from 0.1 to 0.5 mg·dm–3). Calycanthus multiplication in vitro shouldbe conductedon WPM media with 1.0 mg·dm–3 BAP. Proliferatedshoots were placedon the WPM rooting medium supplemented with auxins: IBA, IAA or NAA at the concentration from 0.1 to 2.0 mg·dm–3. Maximum rooting was obtained on WPM medium supplemented with 0.5 mg·dm–3 IBA. To sum up, it shouldbe statedthat an efficient method of micropropagation of Calycanthus fertilis Walt. has been developed.

Bambusa balcooa.Roxb. is one of the most commercially important bamboo species. Some varieties of bamboo are being grown in the company’s green house. However this species is very rare and it was not cultured until now due to lack of demand and maintenance problems. In this work B. balcooa ex-plants have been established and propagated by the axillary shoot bud proliferation method. Earlier several works have been done on this plant and a protocol has been. This work emphasizes on effects of phytohormones at different concentrations and combinations upon the novel propagules that develop from the bamboo explants on placing them in multiplication media. The propagules placed in media containing cytokinins BAP (2 mg/L) and Kinetin (1 mg/L) exhibited best results of linear as well as radial growth. The other propagules in media with combinations of BAP, Kinetin and NAA were found to be dried out and did not depict noticeable growth. Comparatively next best growth pattern to the former was observed in control media that lacked phytohormones. This experiment was helpful in estimating the quantity and effect of particular plant growth regulating hormones on the Bambusa balcooa.Roxb.

Opis:
Trinexapac-ethyl is a popular plant growth regulator used in various crops, mostly due to its unique anti-lodging properties. Recently it has been found that this substance is also active in stress protection, which may increase its importance in the coming years. This paper presents a new approach to its application. Trinexapac-ethyl belongs to the cyclohexanedione class of herbicide chemistry, thus it is structurally similar to common graminicides frequently used with adjuvants. Th is study examines the effects of the application of trinexapac-ethyl with adjuvants. Field trials were conducted in the Institute of Plant Protection in Poznań (Poland), in 2014 and 2015. Trinexapac-ethyl was applied at recommended (0.4 l · ha–1) and reduced doses (0.2 l · ha–1) with organosilicone surfactant, ammonium sulphate and citric acid on spring barley. Stem shortening, yield components and grain quality were examined. The results of the study confirmed the possibility of dose reduction of trinexapac-ethyl by way of combined application with citric acid that reduced the pH of spray liquid or with ammonium sulphate without aff ecting its effectiveness. The greatest stem height reduction was observed after the application of a full dose of trinaxapac ethyl and its reduced dose in the mixture with citric acid or ammonium sulphate. Depending on the year of study, the eff ectiveness of the substances on stem reduction ranged from 5.6 to 16.5%. The tested mixtures did not have any significant impact on the number of grains per ear or the yield of spring barley. Trinexapac-ethyl and its mixtures with adjuvants did not influence the crude protein and starch in spring barley grains.

Opis:
Field experiments were conducted in two localities: Prusy (50°07’ N; 20°04’ E – one experiment) and Wierzbica (50°29’ N; 19°45’ E – two experiments) in 2003. The objective of this study was to analyse the influence of agronomic factors on the grain yield and on the content of macroelements in grain of different forms of naked oat. In Wierzbica the grain yield was determined statistically by the genotype, the phosphorus and potassium fertilization and the application of the plants growth regulator Moddus. In Prusy grain yield was determined only by the genotype (cultivars, strains). A concentration of macroelements in forms of oat was statistically different. In both localities the phosphorus and potassium fertilization and foliar application of urea, in general, had not the statistical influence on the content of the macroelements. An exception is the influence of the foliar application of urea on the content of potassium. Plant growth regulator Moddus caused changes in the content of macroelements. These changes were not always statistically significant, but always increased the concentration of macroelements. The second plant growth regulator Promalin did not cause changes in the concentration of macroelements.
Badano wpływ czynników agrotechnicznych na zawartość wybranych składników mineralnych w ziarnie nagoziarnistych form owsa uprawianych w dwóch miejscowościach. Doświadczenia polowe prowadzono na glebie brunatnej typowej (Wierzbica – 50°29’ N; 19°45’ E) i na czarnoziemie zdegradowanym (Prusy 50°07’ N; 20°04’ E). W Wierzbicy plon ziarna był różnicowany statystycznie przez genotyp, nawożenie fosforowo-potasowe oraz stosowanie regulatora wzrostu Moddus. W Prusach jedynym czynnikiem modyfikującym statystycznie plon ziarna był dobór odmiany/rodu. W obydwu siedliskach nawożenie fosforowo-potasowe i dolistne azotem na ogół nie miało statystycznie istotnego wpływu na zawartość makroskładników. Wyjątek stanowił wpływ nawożenia dolistnego azotem na zawartość potasu. Spośród regulatorów wzrostu tylko Moddus powodował tendencje do zwiększonej kumulacji makroskładników w ziarnie owsa nagoziarnistego.

Water shortage is a major problem that limits growth and productivity of plants in arid and semi-arid regions. Protecting plants from adverse environmental conditions by using simple methods could be of great value under these conditions. In the present study, we examined water status and drought tolerance of snap bean, a drought-sensitive plant, and Jerusalem artichoke, a relatively drought tolerant plant in response to the application of salicylic acid (SA). Different levels of SA were applied and several physiological, growth, productivity and quality parameters were recorded together with the relative water content. Foliar application of SA improved growth, productivity, quality as well as some physiological parameters of snap bean and Jerusalem artichoke plants exposed to drought stress. Total chlorophyll content and relative water content were higher in plants treated with SA compared to control plants when subjected to drought stress. The specific responses of snap bean and Jerusalem artichoke to SA under drought stress as well as the possible explanations of the effects of SA are discussed.

In order to develop an efficient micropropagation system, it is essential to establish the appropriate concentration of growth regulators for seed germination, shoot formation and rooting. Nodal segments from in vitro obtained seedlings of Gentiana lutea L. were cultured in vitro in Murashige and Skoog’s medium supplemented with BAP, Thidiazuron and Zeatin (0.5, 1.0 and 2.0 mg L−1). A maximum number of shoots with the highest height was recorded at 2.0 mg L−1 BAP. For further optimization of the process, we used nutrient media containing BAP and Zeatin with a combination of low concentration of Indoleacetic acid. MS medium containing 2.0 mg L−1 Zeatin and 0.2 mg L−1 IAA resulted in maximum numbers of shoots 94.3) with shoot height 2.5 cm. The multiple plants were successfully ex vitro acclimatized with 65% survival. The presence of growth regulators (2.0 mg L−1 Zeatin and 0.2 mg L−1 IAA) in the nutrient media resulted in an effective antioxidant activity in G. Lutea determined by the low molecular antioxidant metabolites such as phenols and flavonoids and activities of antioxidant enzymes – catalase, ascorbate peroxidase, guaiacol peroxidase, and superoxide dismutase. The described protocol allows the establishment of numerous micropropaged plants of rare and endangered G. lutea.

Opis:
The components crucial for fulfilling plant nutrient needs are, beside macroelements, also microelements. Microelement content in plant raw materials is often modified by various agronomic measures, therefore it does not always meet the requirements for this element. The research was conducted to determine the effect of agronomic factors on the content of zinc, copper, iron, cobalt and manganese in oat grain. Three field experiments were set up acc. to fractional factorial designs (25–1 and 34–1) in two localities (Wierzbica and Prusy) in 2003. Akt cv. revealed a lower content of zinc, copper, iron and manganese in comparison with STH 7000 and STH 4770 strains. Microelement concentrations in oat grain were determined by the selection of oat cultivar/strain and growth regulator dose. Zinc content in oat grain fulfilled the requirements for plants designed for human consumption and animal feeds. Optimal iron content but deficient contents of manganese, copper and cobalt were registered in oat grain treated as fodder.
Składnikami niezbędnymi do pokrycia potrzeb pokarmowych roślin, obok makroskładników, są również mikroelementy. Zawartość mikroelementów w surowcach roślinach jest często modyfikowana różnymi zabiegami agrotechnicznymi, dlatego też nie zawsze odpowiada zapotrzebowaniu na ten składnik. Celem przeprowadzonych badań było określenie wpływu czynników agrotechnicznych na zawartość cynku, miedzi, żelaza, kobaltu i manganu w ziarnie owsa. Trzy eksperymenty polowe założono według planów frakcyjnych (25–1 i 34–1) w dwóch miejscowościach (Wierzbica i Prusy) w 2003 r. Odmiana Akt cechowała się niższą zawartością cynku, miedzi, żelaza i manganu w porównaniu do rodów STH 7000 i STH 4770. Zawartość mikropierwiastków w ziarnie owsa była determinowana doborem odmiany/rodu owsa oraz dawką regulatora wzrostu. Zawartość cynku w ziarnie owsa spełniała wymogi stawiane roślinom przeznaczonym na cele konsumpcyjne i paszowe. Stwierdzono optymalną zawartość żelaza, a niedoborową manganu, miedzi i kobaltu w ziarnie owsa traktowanego jako pasza.
