drought is one of the most important factors limiting growth and yield in many parts of the world. in order to evaluate the effects of drought stress on some morphological and physiological traits of two cultivars of bean, two red beans (derakhshan and goli) in four drought treatments including 25%, 50%, 75%, control 100% field capacity were studied in a factorial experiment based on complete r...

drought is one of the most important factors limiting crop yields around the world. drought stress in plants, the change (increase or decrease) in the production of plant proteins. this research was carried out using bread wheat genotypes. for evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....

Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...

in order to evaluate drought tolerance of some aegilops triuncialis ecotypes a factorial experiment based on a completely randomized design was conducted under non-stress and drought stress (irrigation until 50% of heading) condition in the greenhouse of mohaghegh ardabili university in 2012. drought tolerance and susceptibility indices for grain yield were calculated and principal component an...

the responses of yield and yield components of 24 advanced bread wheat genotypes to pre- and post-anthesis drought stress conditions were studied at ardabil agricultural re-search station during the 1997-2000 cropping seasons. results showed that genotypes produced significantly lower spikes no./m2, seeds no./spike and grain yield under pre- than in post-anthesis drought stress conditions. howe...

pinto bean is a susceptible plant to drought stress. however, there is genotype variation for this trait in this plant. in order to investigate the effects of drought stress on physiological traits and grain yield of pinto bean genotypes cultivated in zanjan province, an experiment was conducted as spilt plot based on a completely randomized block design with four replications at zanjan univers...

Drought stress is the most common environmental stress that can significantly influence crop productivity. In this study, morphological and biochemical properties of 17 genotypes of common bean were evaluated under different levels of drought stress and the most sensitive and tolerant genotypes were identified using multivariate analysis. The results indicated that morphological and biochemical...
