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...
Drought is a major constraint for sunflower (Helianthus annuus) production worldwide. Drought tolerance traits have been identified in the related wild species Helianthus argophyllus. This study was initiated to develop sunflower drought-tolerant genotypes by crossing cultivated sunflower with this species and analyze drought tolerance traits in the H. annuus and H. argophyllus populations, H. ...
Heat shock proteins (HSPs) perform significant roles in conferring abiotic stress tolerance to crop plants. In view of this, HSPs and their encoding genes were extensively characterized in several plant species; however, understanding their structure, organization, evolution and expression profiling in a naturally stress tolerant crop is necessary to delineate their precise roles in stress-resp...
drought is one of the most important abiotic stresses affecting plant growth and development. in the present study, the changes in lipid peroxidation rate and antioxidant enzyme activities were determined at different concentrations of polyethylene glycol (peg) 6000 (0, 5, 10, and 15% (w/v)) for two canola cultivars (slm046 and hyola 308). in order to produce water deficit, 12 days old canola s...
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.

In order to evaluate the effects of both cold and light stresses on chlorophyll fluorescence and feasibility of using chlorophyll florescence technique to evaluate effect of light intensity on cold tolerance in soybean, an experiment was done in a factorial arrangement based on a completely randomized design with three replicates. Two soybean cultivars consisted of 032 and BP grown under greenh...
Drought and salinity are the major environmental factors that affect rice productivity. Comparative transcriptome analysis between tolerant and sensitive rice cultivars can provide insights into the regulatory mechanisms involved in these stress responses. In this study, the comparison of transcriptomes of a drought-tolerant [Nagina 22 (N22)] and a salinity-tolerant (Pokkali) rice cultivar with...
This investigation was done in order to study the response of grain yield and yield components of bread wheat cultivars to drought stress in western Iran in 2008-2009. The main plots were levels of drought stress (full irrigation, stress at early stem elongation, flowering and grain filling stages) and subplots were five cultivars (Chamran, Dez and Verinak). The results indicated that the effec...
zagros (drought tolerant) and pishtaz (drought susceptible) cultivars were classified on the basis of shoot dry weight and were used as plant material in this study. total chlorophyll, carotenoids, antocyanins, proline, soluble sugar contents, lipid peroxidation, antioxidant enzyme activities and protein patterns were determined. seedlings of wheat genotypes were grown in nutrient solution cult...
the selection of high yielding and stress tolerance plant genotypes with the highest water use efficiency and productivity is one of the most important tools for field water management in arid and semi-arid regions. this study was conducted to identify drought tolerant flax families with the highest irrigation water productivity (iwp) among a population of 119 f3 families derived from a cross b...
