One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...
the effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (brassica napus l.) grown in the hoagland solution. the growth of treated plants was inhibited under lead stress. lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgl-1 of pb. hyola308 cultivar showed low biomass...
root depth and distribution have an important role in drought resistance and optimization of moisture content of soil. this research was carried out in order to consider of root response of triticale genotypes to water stress and recognition of root trait that can effective in resistance of water stress. this experiment was in a factorial experiment based on completely random design on the year...
partitioning of photoassimilates between the sinks is one of the most important physiological processes related to the yield of crops which are affected by drought stress. therefore, the effect of drought stress in flowering and grain filling stages, on the percentage partitioning of photoassimilates among different organs was studied in 14 rapeseed cultivars in a split plot experiment based on...
This study was conducted at the Research Farm of Isfahan University of Technology in 2003 to evaluate drought tolerance potential of 20 oat (Avena sativa L.) genotypes including 14 cultivars released in Canada, two cultivars released in the United States of America and Switzerland and four Turkish breeding lines. A randomized complete block design with three replications was used in each irriga...
Water shortage seriously threatens crop growth and development especially in semi-arid areas. Association of plants with beneficial soil microorganisms is a strategy for plant adaptation to environmental stresses. In this study, the effect of seed inoculation of rapeseed genotypes with mycorrhiza-like fungus (Piriformospora indica) and growth-promoting bacterium (Arthrobacter siccitolerans) was...
climate changes due to global warming is affecting world agriculture adversely. heat stress due to global warming has turned to one of the most important factors reducing quantity and quality of plants production such as tomato. despite of wide cultivation of tomato and high temperature effects on its production, unfortunately; research in this area is scarce. this study was conducted to invest...
Determining environment – associated alterations in grain yield is important in yield assessment under drought stress. Therefore this study was carried out to determine the correlation coefficients and direct and indirect effects of effective components on yield in four drought - tolerant and susceptible cotton cultivars. Cotton cultivars were considered as sub plots and 3 levels of irrigation ...
to study the impact of growth factor bacteria , humic acid and alga extract in drought stress condition a test is established in form of completely random blocks and spilt plot in 4 replications in a field in mahallat in arak province in 1389. two primary plots including irrigation and stress and secondary plots including growth factor bacteria ,humic acid and alga extract, ascophylu...
