    Opis:
    The biostimulant products are able to improve quality and quantity of medicinal plants. The comparative effects of biostimulants foliar spraying on peppermint (Mentha piperita L.) were investigated. These studies were done on the basis of randomized complete blocks design in 3 replicates during 2015. In field conditions, the highest leaves and stems dry weight by 400 mg/l chitosan (CH) + 400 mg/l citric acid (CA), essential oil content by 200 mg/l chitosan + 400 mg/l humic acid (HA) + 400 mg/l citric acid and menthol content in 200 mg/l chitosan + 800 mg/l humic acid + 400 mg/l citric acid were observed. In greenhouse conditions, the best results of those mentioned parameters were obtained by 400 mg/l chitosan + 800 mg/l humic acid + 400 mg/l citric acid, 800 mg/l humic acid and 400 mg/l chitosan + 400 mg/l humic acid + 400 mg/l citric acid, respectively.

    Opis:
    The aims of the study were to determine the effect of temperatures and precipitation on the ring width and to compare the results with the results of previous studies conducted in other mountain ranges of the Czech Republic. The research was performed in the central part of the Ceskomoravská Upland in the vicinity of Herálec municipality in selected 70- up to 110-year-old spruce stands at altitudes from 680ma.s.l. to 779 m a.s.l. Measuring of tree-ring widths and synchronization of individual ring series were conducted in PAST4. The age trend was removed by ARSTAN and climatic effects were modelled in DendroClim2002. The correlation of tree-ring width with monthly precipitation is positive and statistically significant for July of the previous year and for the entire summer period from June to September of the current year. The correlation of tree-ring width with mean monthly temperatures is negative and statistically significant for July and September and positive and statistically significant for October of the previous year. Negative correlation was also found for temperatures of the entire summer period from June to September of the previous year. The regional tree-ring chronology mainly shows two periods of highly reduced increment: from 1992 to 1996 and from 2003 to the end of the analysed period. The results thus confirm the hypothesis that the tree-ring width is in positive correlation with summer precipitation and negative correlation with summer temperatures. Also the results of the habitual diagnostics have shown a relatively low degree of crown transformation which indicates a weak or short-term stress load.

    Opis:
    While each individual root responds to such environmental factors as light or gravity the question arises how these reactions subordinate to the whole root system, which is supposed to maintain its primary functions. Data presented here confirm that in cucumber the gravity and light modulate the growth direction of the lateral roots subunits of the system. Another important factor affecting behavior of lateral roots is an orientation of the main root. These facts all together suggest that the root system functions as an integrated entity, capable of adapting its architecture to changing environmental conditions. Its flexibility, based on unknown signaling network, guarantees optimal functioning of the system.

    Opis:
    The aim of the research was to assess the degree of damage to spruce trees and stands and to study their growth responses to the changing environmental conditions in the Sowie Mountains (Central Sudety Mts.). To assess the degree of damage to trees, three methods based on crown characteristics were used. The types of growth responses of trees to changing environmental conditions were additionally taken into account in one of the methods. Regardless of the assessment method, spruce stands in the Sowie Mountains demonstrated a high level of damage. The poorest growth conditions were found in the period 1966−1980 when a large number of trees showed negative growth responses, indicating a decrease in radial increment. The period 1996−2010 showed an improvement in the growth conditions of trees because the proportion of trees with negative growth responses decreased, while the proportion of trees with positive growth responses increased. It was also found that the growth conditions for spruce were more favourable in the lower montane forest zone (above 600 m a.s.l.), and less favourable at the foothills (below 600 m a.s.l.), which may be caused by the competition of beech replacing spruce in the lower locations in the mountains.

    Opis:
    The growth response of oak to anthropogenically−induced changes in the environmental conditions was analysed in four habitats and three time intervals distinguished on the basis of fluvial water levels and the time of dam construction in Brzeg Dolny. The obtained results indicate that the conditions of growth in the examined stands prior to dam construction did not differ between individual habitats. Immediately after dam completion, the growth conditions deteriorated, so the growth response of oak considerably differed between the habitats. The growth conditions in the last period under analysis established and the diameter growth of trees in habitat IV again attained the status comparable to that from before the occurrence of a stress factor. Avoidance of any rapid changes in water management of forest habitats is the most important factor conditioning further forest management in the given area.

    Opis:
    Declining soil fertility is one of the main causes of low yields of maize. Farmers apply low rates of unbalanced nutrients leading to further nutrient mining. A randomized complete block nutrient omission trial with six replications was therefore set to determine maize response to the application of a wide range of nutrients from inorganic fertilizers on Ferralsols. The treatments were NK, NP, PK, NPK, and NPK + CaMgZnBS. The results showed that application of PK fertilizer resulted in low crop growth rate (CGR), and relative growth rate (RGR), and biomass compared to other treatments. Application of a wider range of nutrients (NPK + CaMgZnBS treatment) improved maize growth and yield compared to other treatments. In terms of grain response, Urea application recorded the highest yield (1800 kg/ha) followed by Triple Superphosphate (1300 kg/ha) then Muriate of potash (1100 kg/ha) and least by a combined application of secondary nutrients and micronutrients (ZnBMgCaS = 400 kg/ha). Highest agronomic efficiency of 32.5 kg grain /kg P applied was recorded due to P followed by K (27.5 kg grain /kg K) and least by N (15 kg grain /kg N). Based on the combined effect, application of N-P-K based fertilizers could give better yields. Use of micronutrients should be assessed further for conclusive recommendations.

    Opis:
    Root-knot nematodes have become a grave menace to the lucrative production of cucumber throughout the world. These nematodes are mainly controlled by applying nematicides, but their use is often associated with hazards. Alternatively, the use of nematode resistant cultivars is considered to be innocuous and economically feasible. For their fitness as nematode-suppressive crops, the reduction in growth and yield parameters of these cultivars must be assessed. As there is little documented data about the effects of Meloidogyne incognita on the damage of cucumber, therefore, in the present study, the effects of M. incognita were evaluated on growth and yield parameters of fifteen cucumber cultivars. M. incognita significantly negatively affected the growth and yield parameters of all the cucumber cultivars. Shoot and root lengths and shoot weights of all the cultivars were significantly reduced as a result of nematode infection. Maximum reductions in these parameters were recorded in highly susceptible cultivars followed by susceptible ones, while the reductions were minimal in resistant followed by moderately resistant cultivars. On the contrary, the infection by M. incognita resulted in an increase in root weights of all the cultivars. The increase was found to be the maximum in highly susceptible cultivars followed by susceptible and moderately susceptible cultivars. Likewise, the minimum increase was observed in the resistant cultivars followed by moderately resistant cultivars. Similarly, significant variations in yield parameters among fifteen cucumber cultivars were also recorded as a result of M. incognita infection. In the case of highly susceptible cultivars, the reductions in yield parameters were maximum, whereas the reductions in resistant and moderately resistant cultivars were found to be minimum. As cultivars Long Green, Marketmore, Pioneer-II, Dynasty and Summer Green experienced no significant damage compared to susceptible cucumber cultivars and therefore, they are approved for cultivation in nematode infested soils.

    Opis:
    In this contribution we deal with a new mathematical description of the response of short-term coleoptile/hypocotyl expansion growth to temperature. Although the interest of both the bio-mechanical basis of elongation growth and temperature responses has been studied in plant biology and biophysics for a long time, yet the question of the mode of actions of temperature is very relevant and still open. Here we introduce a simple idea that the normal distribution, due to the central limit theorem (CLT), is able to report on temperature-dependent elongation growth. The numerical fittings for temperature affected growth are in good agreement with empirical data. We suggest that the observation concerning a crossover effect occurring in temperature driven elongation together with CLT leads to the formulation of a hypothesis about the possible universal character of such a description, supposedly for many plant species and families. We conclude with the statement that properly constructed equations of temperature affected growth, should possibly include a specific term proportional to exp[-((T-T0)/T0)2] with T0 corresponding to the temperature of the optimum growth.

    The aim of this research was to assess damage to three important forest−forming trees species in the mountains – spruce, fir and larch, and to study their increment reaction to changing environmental conditions. Research concerned forests under the management of four forest districts located in the Western Sudetes (SW Poland). Index W ranging from 0 to 3 was used for the assessment of the damage to trees based on three crown characteristics: defoliation, top−crown condition and tree vitality. Trees of damage degree 2 dominated in each of the species; dying trees (degree 3) were also found. Total share of these two degrees of damage was ca 80% for spruce, 84% for fir and 74% for larch. Analysis of increment reaction of investigated species showed their similar response to changes in the environment. The increase in the share of trees showing positive responses and the decrease in the share of negative responses in the past half century, indicate an improvement in the growth conditions of spruce, fir and larch in Western Sudetes.

    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:
    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:
    Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and non-mycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.

    Opis:
    Green revolution increased the food production enormously to feed the geometrically growing population. In India, the availability and affordability of fossil fuel based chemical fertilizers at the farm level have been ensured only through imports and subsidies. Dependence on chemical fertilizers for future agricultural growth would mean further loss in soil quality. The possibilities of water contamination and unsustainable burden of the fiscal system. The Government of India has been trying to promote an improved practice involving use of biofertilizers along with fertilizers. These inputs have multiple beneficial impacts on the soil and can be relatively cheap and convenient for use. The agricultural chemicals like pesticide and weedicides were being used to save the standing crop from the attack of pests and to boost crop production. At the same time the excess use of chemical fertilizers degraded the soil properties. In this context, the farmers are expecting for the cheapest and eco-friendly alternative for getting higher yield. Biofertilizers is only the alternative way to get more production without harmful to environment. So the effect of different doses of biofertilizer (Rhizobium) on germination studies of Fenu-greek seed germination percentage, seedling growth, fresh weight and dry weight, chlorophyll, protein and soluble sugar content has been studied in the laboratory condition. There parameters increased to application when biofertilizer compared to control.

    Opis:
    The aim of the study was to examine the efficiency of foliar zinc (Zn) application in pear culture. The experiment was carried out in 2005-2007 in a commercial orchard in central Poland, on 6-8 year-old cv. Lukasovka pear trees, grown on coarse-textured soil, moderately abundant in organic matter or available Zn and slightly acidic in reaction. The trees were sprayed with Zn as EDTA in three periods: (1) before bloom: at the stage of bud break, and green and white bud, at a rate of 80 g Zn ha-1 in each spray treatment; (2) after bloom: at petal fall, and 14 and 21 days after full bloom, at a rate of 50 g Zn ha-1 per spray or; (3) after harvest, 3-4 weeks before natural leaf fall, at a rate of 200 g Zn ha-1. Trees unsprayed with Zn served as the control. The results showed, that pre-bloom Zn sprays increased status of this micronutrient in flowers, and post-bloom Zn sprays – in leaves and fruits. However, foliar Zn sprays had no effect on tree vigor, set of flowers and fruitlets, yielding, mean fruit weight, fruit russeting, and content of organic acids and soluble solids in fruit flesh. It is concluded that foliar Zn sprays of pear trees with an optimal leaf Zn status (according to the current threshold values) are not successful in improving plant growth, yielding, and fruit quality.
    Celem badań była ocena skuteczności dokarmiania dolistnego cynkiem (Zn) w uprawie gruszy. Doświadczenie przeprowadzono w latach 2005-2007 w prywatnym sadzie w centralnej Polsce. Obiektem doświadczalnym były 6-8-letnie grusze odmiany Lukasówka/pigwa S1, rosnące na glebie o składzie mechanicznym piasku gliniastego lekkiego, umiarkowanej zawartości materii organicznej, lekko kwaśnym odczynie oraz o średniej zawartości Zn. Grusze opryskiwano Zn w formie EDTA w trzech okresach: (1) przed kwitnieniem: w fazie pękania pąków oraz zielonego i białego pąka, w dawce 80 g Zn ha-1 w każdym zabiegu; (2) po kwitnieniu: w fazie opadania płatków kwiatowych oraz 14 i 21 dni później, w dawce 50 g Zn ha-1 w każdym zabiegu lub (3) po zbiorze owoców, 3-4 tygodnie przed naturalnym opadaniem liści, w dawce 200 g Zn ha-1. Drzewa nie opryskiwane Zn stanowiły kontrolę. Wykazano, że opryskiwanie Zn przed kwitnieniem zwiększyło zawartość tego mikroskładnika w kwiatach, a opryskiwanie po kwitnieniu – w liściach i owocach. Dokarmianie dolistne Zn nie miało jednak wpływu na wigor drzew, zawiązywanie kwiatów i owoców, plonowanie, średnią masę owocu, ordzawienie owoców oraz zawartość kwasów i ekstraktu w miąższu owoców. Wnioskuje się, że dokarmianie dolistne Zn grusz o optymalnej zawartości tego mikroskładnika w liściach (wg obowiązujących liczb granicznych) nie polepsza wzrostu i plonowania roślin oraz jakości owoców.

    Opis:
    Plant breeders have focused much attention on polyploid trees because of their resistance for forestry. To evaluate the impact of intraspecies genome duplication on NaHCO3 stress, a series of Betula platyphylla autotetraploids and diploids were generated from the same family. The growth, proline content and proline-associated gene expression of these autotetraploid individuals were compared with those diploid trees. Autotetraploids were superior in injury index and relative growth of height and base diameter compared to diploids. The proline content was higher in autotetraploid individuals compared to diploids. Gene expression data revealed autotetraploids were generally higher expression in BpP5CS1, BpP5CS2, Bp- P5CR1, BpP5CR2, BpP5CR3 and BpOAT and were lower expression in BpProDH and BpP5CDH compared to diploid trees. These results shed light on resistance variation in birch autotetraploidization and polyploidy breeding as a new approach for genetic improvement of birch trees.

    Opis:
    W pracy przedstawiono wyniki badań wpływu zawartości chlorku sodu (NaCl) w pożywce Hoaglanda o stężeniach 25, 50, 75 mmol·dm-3 na wzrost oraz intensywność fotosyntezy siewek soi dwóch odmian Nawiko i Progres. Określono świeżą i suchą masę części nadziemnej i korzeni siewek soi badanych odmian oraz wykonano pomiary intensywności fotosyntezy. Zaobserwowano, że wraz ze wzrostem stężenia NaCl w pożywce statystycznie istotnie obniża się świeża i sucha masa części nadziemnej roślin obu odmian. Nie stwierdzono wpływu zwiększającego się stężenia NaCl w pożywce na świeżą masę korzeni obu badanych odmian soi. Jedynie w przypadku suchej masy korzeni odmiany Nawiko negatywny wpływ zanotowano przy stężeniu NaCl 75 mmol·dm-3. Najwyższe stężenia NaCl w pożywce (75 mmol·dm-3) spowodowały upośledzenie zdolności asymilacji ditlenku węgla (CO2) roślin obu odmian. Uzyskane wyniki wykazały, że młode rośliny odmiany Progres są bardziej tolerancyjne na stres solny niż odmiany Nawiko.
    The influence of NaCl content in Hoagland medium – in concentrations of 25, 50, 75 mmol dm-3 – on the growth and photosynthesis of soybean seedlings (cv. Progres and Naviko) was studied. Fresh and dry weights of shoot and root and photosynthesis intensity were determined. It was observed that with increase of NaCl concentration in the medium there is a significant decrease of the fresh and dry weight of the shoot in plants of both cultivars. There was no effect of increased NaCl concentration in the medium on the fresh weight of the roots of the two soybean cultivars. Only in the case of the dry weight of roots a negative effect was noted for Naviko cultivar at NaCl concentration of 75 mmol dm-3. The higher concentration of NaCl in the medium (75 mmol dm-3) caused a impairment of CO2 assimilation of both soybean cultivars. The results showed also that young plants of Progres cultivar more salt stress tolerant than Nawiko cultivar.

    Opis:
    The actual yields of sugar beets harvested by farmers in Poland are much below the yielding potential of currently cultivated varieties, even when grown on fertile soils. Deficiency of micronutrients can be considered as a factor which prohibits reaching a state of nutrient balance, especially in nitrogen, by a crop. The aim of the study was to assess the effect of foliar application of multi-microelement fertilizers on a sugar beet nutritional status in early stages of canopy growth and, in turn, on yields of taproots and recoverable sugar. For this purpose, in two growing seasons, 2005 and 2006, eight field trials were set up in the region of Wielkopolska on fertile soils originated from sandy loam. A simple experimental design comprised three treatments: (1) control (a plot fertilized only with NPK), and (2) multi-microelement fertilizer composed of cations (Mi), (3) cations plus boron (MiB). It has been found that the applied micronutrient fertilizers had a significant effect, irrespectively of the field location and seasonal yield variability, on the sugar beet nutritional status, especially in terms of nitrogen. Yields of taproots have increased by 31.6% and 22.1% for the NPK+Mi and NPK+MiB treatments, respectively. Almost the same degree of increase was noted for yields of recoverable sugar. The achieved nitrogen balance at the stage of harvestable part development, as measured at BBCH43, was probably the main reason for high positive response of sugar beet crop to external supply of micronutrients. All the analyzed standards of sugar beet nutritional status, DRIS indices, responded to the investigated experimental factor, i.e., foliar application of multi-microelement fertilizer, but only those for nitrogen underwent a change from negative to positive values, thus enabling us to make a reliable yield prognosis.
    Plony buraków cukrowych zbierane przez rolników w Polsce kształtują się na poziomie dużo niższym, nawet na glebach żyznych, niż plony potencjalne obecnie uprawianych odmian. Niedobór mikroelementów może być rozważany jako jeden z czynników, który uniemożliwia uzyskanie przez rośliny stanu równowagi żywieniowej, zwłaszcza w przypadku azotu. Celem badań była ocena wpływu dolistnie stosowanych wieloskładnikowych nawozów mikroelementowych na stan odżywienia roślin we wczesnych fazach rozwoju buraków, i w konsekwencji na plony korzeni i cukru. Cel zweryfikowano w latach 2005 i 2006, zakładając w Wielkopolsce 8 doświadczeń zlokalizowanych na żyznych glebach, wytworzonych z polodowcowych glin moreny dennej. Prosty schemat doświadczenia zawierał 3 kombinacje: (1) kontrolę (obiekt nawożony NPK) oraz 2 obiekty z dolistnie stosowanymi nawozami mikroelementowymi wieloskładnikowymi zawierające w swym składzie (2) kationy, (Mi), (3) kationy i bor (MiB). Stwierdzono, niezależnie od lokalizacji doświadczenia i zmienności sezonowej plonów, istotne działanie nawozów mikroelementowych na stan odżywienia roślin, zwłaszcza azotu. Plony korzeni zwiększyły się o 31.6% i 22.1%, odpowiednio w przypadku wariantu Mi i MiB. Analogiczną reakcję odnotowano dla plonów cukru. Główną przyczyną dodatniej reakcji buraków cukrowych na dolistną aplikację nawozów mikroelementowych było uzyskanie przez rośliny w fazie BBCH43 zbilansowanego stanu odżywienia roślin azotem. Analizowane normy odżywienia roślin, indeksy DRIS, wykazały reakcję na badany czynnik doświadczalny, czyli nawozy mikroelementowe wieloskładnikowe, lecz tylko w przypadku azotu nastąpiła zmian wartości indeksów z ujemnych na dodatnie, umożliwiając tym samym wiarygodną prognozę plonów.

    Opis:
    In vitro flowering and micropropagation are useful for plant breeding programs and commercial production of important ornamental plants. In vitro conditions including media components, kind, concentration and ratio of plant growth regulators and culture conditions significantly affect in vitro flowering and micropropagation. There is no any report dealing with the in vitro flowering of Lisianthus (Eustoma grandiflorum). Here, a protocol was developed for flowering and high frequency in vitro micropropagation of E. grandiflorum, an ornamental plant. Micropropagation is an effective tools for propagation of ornamental plants in large scale. The aim of the present study was to evaluate the effect of different concentrations of NAA and BA on micropropagation and flowering of Lisianthus, in vitro. Used culture medium was MS enriched with 0, 0.1, 0.2 and 2 mg L-1 of NAA and BA. In establishment process of explants, the most shoot length (2.07 cm per plant) was obtained on medium supplemented with 0.1 mg L-1 BA (without NAA). Maximum shoot number (5.80 per plant) was produced in medium containing 0.1 mg L-1 BA along with 0.2 mg L-1 NAA. Bud explants in culture media containing 0.2 mg L-1 NAA (without BA) and 0.1 mg L-1 NAA along with 2 mg L-1 BA produced maximum node number (3.20 per plant). The largest number of root (14.53 per plant) and root length (3.87 cm per plant) were produced on 0.2 mg L-1 NAA without BA, also 0.2 mg L-1 BA plus 0.2 mg L-1 NAA and 0.2 mg L-1 BA without NAA. Explants produced flower on medium containing 0.1 mg L-1 BA along with 0.1 mg L-1 NAA without transition of callus formation. Flower was produced from callus in medium containing 0.1 mg L-1 BA along with 2 mg L-1 NAA. Regenerated plants showed 98% survival in greenhouse during acclimatization. Acclimatized plants were morphologically similar to the mother plants.
    Kwitnienie i mikropropagacja in vitro są użyteczne w programach hodowli roślin oraz produkcji komercyjnej ważnych roślin ozdobnych. Warunki in vitro, łącznie ze składnikami pożywek, rodzajem, stężeniem oraz proporcją regulatorów wzrostu roślin, a także warunkami hodowli, w sposób istotny wpływają na kwitnienie i mikropropagację in vitro. Nie istnieje żadne badanie dotyczące kwitnienia in vitro lisanthiusa (Eustoma grandiflorum). W niniejszym badaniu opracowano kwitnienie i wysoką częstotliwość mikropropagacji in vitro dla E. grandiflorum, który jest rośliną ozdobną. Mikropropagacja jest skutecznym narzędziem rozmnażania roślin ozdobnych na dużą skalę. Celem niniejszego badania była ocena wpływu różnych stężeĔ NAA i BA na mikropropagację i kwitnienie lisianthiusa in vitro. Używana pożywka hodowlana została wzbogacona za pomocą 0; 0,1; 0,2 i 2 mg L-1 NAA i BA. Przy powstawaniu eksplantów największa długość łodygi (2,07 cm na roślinę) była uzyskana na pożywce uzupełnionej o 0,1 mg L-1 BA (bez NAA). Maksymalna liczba łodyg (5,80 na roślinę) została wytworzona na pożywce zawierającej 0,1 mg L-1 BA wraz z 0,2 mg L-1 NAA. Eksplanty pączków na pożywce hodowlanej zawierającej 0,2 mg L-1 NAA (bez BA) oraz 0,1 mg L-1 NAA wraz z 2 mg L-1 BA wytworzyły maksymalną liczbę węzłów (3,20 na roślinę). Największą liczbę korzeni (14,53 na roślinę) oraz największą długość korzenia (3,87 na roślinę) zaobserwowano na 0,2 mg L-1 NAA bez BA jak również 0,2 mg L-1 BA plus 0,2 mg L-1 NAA oraz 0,2 mg L-1 BA bez NAA. Eksplanty tworzyły kwiat na pożywce zawierającej 0,1 mg L-1 BA wraz z 0,1 mg L-1 NAA bez przeniesienia kalusa. Kwiat był tworzony z kalusa na pożywce zawierającej 0,1 mg L-1 BA wraz z 2 mg L-1 NAA. Zregenerowane rośliny wykazały 98% przeżycie w szklarni podczas aklimatyzacji. Zaaklimatyzowane rośliny były morfologicznie podobne to swych roślin macierzystych.

    Opis:
    The recent experiment was conducted to assess the effect of herbicide (quizalafop-p-ethyl) on growth, photosynthetic pigments, enzymes and yield of Black gram (Vigna mungo L.) during the summer season 2013-2014. This experiment comprised black gram (variety ADT 3) and different concentrations of herbicide (quizalafop-p-ethyl) treatments compared with control. Reduction in growth, photosynthetic pigments, enzymes and yield parameters were observed with 0.5 % herbicide application followed by 1 %, 1.5 % and 2 %, out of all treatments 0.5 % shows least reduction. Thus, 0.5 % herbicide application is the safest way for weed control in Black gram field as it showed least adverse effect on growth, photosynthetic pigments, enzymes and yield of crop when compared with other treatments.

    Opis:
    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.

    Opis:
    The paper analyses the height growth and the of height increment of the 18 year−old pine advance regeneration under the shelter of varying canopy densities. A significant effect was found of the stocking of the parental stand on the growth of generation. The height increment increased in response to removal cutting (60% in the second year and 80% in the third year after treatment). In drought years, the greatest relative decrease in height growth of the young−growth stands (by ca 40−60%) occurred in the stands of the greatest canopy closure while it did not occur in the stands to which a removal cutting was applied immediately before the drought year.
