in countries such as iran which will be faced water deficit as the main challenge in the future and the food production is going to be dependent to water recourses, wheat water-deficit tolerant and adapted genotypes release is one of the most important strategies under such a condition. in order to study the adaptation and terminal water deficit stress tolerance, fifteen bread wheat lines and c...

in order to investigate the effects of water deficit at different growth stages of chickpea genotypes, determining the best drought tolerance index and genotypes, an experiment carried out in the saatlu agricultural research station of uromia in 2008-2009. the experiment was split plot based on the randomized complete blocks design with four replications, in which, four levels of irrigation as ...

the deleterious effects of salinity on plant growth and development are associated with the imbalance ion in plant, decreased k+ and increased na+, and ultimately yield loss. in order to evaluate the effects of salinity, 41 bread wheat varieties (trticum aestivum l.) were planted in the randomized complete block design with three replications under two saline irrigation conditions, 0.631 and 11...

to evaluate genetic variation and to study of dry matter remobilization towards seed, 64 bread wheat genotypes were examined in two separated experiments using alpha-latic design of 2 replications during 2002–2003. significant differences observed for most traits in normal and drought conditions. there were considerable variations among genotypes for independent parameters of dry matter remobil...

This study presents the effects of exogenous melatonin application at different concentrations (50, 100, and 200 ?M) on morphological, physiological, antioxidant defense systems buttercup plant under salinity stress (4.5 5.5 dS·m?1 EC). Expectedly, negatively affected growth parameters, cell membrane stability, POX enzyme activity R. asiaticus compared to non-stressed plants. However, in a dose...

in eastern austria, alfalfa is usually grown as a rainfed crop in crop rotations in organic farming systems, where yearto- year rainfall fluctuations cause different levels of drought stress. to identify the suitability of different alfalfa genotypes and drought tolerance indices, 18 contrasting alfalfa genotypes were evaluated under irrigated and rainfed conditions at the research station of t...

to determine chromosomal localization and relationship between field and laboratory indicators of drought tolerance, an experiment was conducted in 2003-2004 cropping season at sararood agricultural research station, kermanshah, iran. seven genotypes of wheat-barley disomic addition lines provided by international center for agricultural research in dryland areas (icarda), their donor and recip...

Fifteen Iranian wheat cultivars (Triticum aestivum L.) were compared for salt (NaCl & Na2SO4 in 1:1 ratio) tolerance using three treatments: 1.26 (control), 6.8 and 13.8 dSm in a green house. During vegetable growth, shoot Na, K, K: Na ratio and agronomic traits such as 1000-grain weight, grain yield, biological yield, number of tillers, number of fertile tillers, spike length, salinity suscept...
