a study was performed to study the effect of drought stress on protein changes of five wheat genotypes. wheat genotypes were planted in early november, growing season of 2008-2009. the experiment was carried out in a factotial design with three replications. two drought stress levels (irrigated and non irrigated) and five genotype of wheat (f103-l-1-12//pony/opata, f1.158/fdl//blo/3/sh14414/cro...

the response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. common bean (phaseolus vulgaris l.) is the most important pulse crop that is cultivated worldwide for human consumption. understanding of the mechanisms responsible for its response to drought is, therefore, essential. an increasing numbe...

rapid germination is an important factor determining the final yield. the most important abiotic stress threatening lentils is drought and temperature. therefore, this study was performed with the aim of investigating effects various thermal treatments (5, 10, 15, 20, 25 and 30°c) and four levels of drought (0, -4, -8, -12 and -16 bar) on percentage and germination rate of lentil genotypes. a s...

in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...

for evaluation of drought tolerance of sugar beet genotypes by assessment of the drought tolerance indices under mild and severe stresses, furrow irrigated field experiments were carried out at zarghan research station in 2002 and 2004, and at motahari research station (located inkaraj) in 2002, 2003, and 2004. the experimental design was split plot, with a randomized complete block arrangement...

water deficit is an important factor limiting crop production worldwide. drought stress can be managed by improving the availability of soil moisture conserved and selecting drought tolerant genotypes. several physiological indices including stomatal conductance (kl), relative water content (rwc), leaf temperature (tl) and crop temperature stability (cts) along with yield, its components and se...

understanding the physiological processes associated with drought stress lead to an understanding of the basic mechanisms of resistance, maintaining yield potential and contribute to the identification of drought tolerant cultivars. for this purpose, the effects of drought stress in cowpea genotypes was evaluated using five different genotypes with different yield potential in a pot experiment ...
