Drought as one of the most important environmental stresses causes serious threats in amount and efficiency of crop productions. To evaluate drought resistance by using drought tolerance indices in safflower varieties, a research was conducted at the Research Farm of Bu-Ali Sina University. Experiment was planed as split-plot on the basis of randomized complete block design with three replicati...

In order to evaluate the response of 20 lines and cultivars of soybean to water deficit stress, an experiment was conducted at Agricultural Research Station of Gorgan in 2011 and 2012. For this Purpose, 2 separate experiments was conducted, each one in randomized complete block design, with 3 replications. In first experiment, all soybean genotypes were irrigated based on 50 mm evaporation from...

  In order to evaluate drought tolerance of some safflower genotypes, an experiment was conducted at the Research Farm of Isfahan University of Technology in 2016 and 2017. In this study, 18 safflower genotypes selected from different local populations along with 2 exotic cultivars and one local population (21 genotypes) were separately evaluated at two normal (non-stress) and water deficit (s...

     In order to study genetic variation and effect of drought stress on grain yield, some agronomical traits and 13 drought tolerance indices, an experiment was conducted on nine cultivars at Shahid Bahonar University of Kerman research field. The experimental layout was conducted in a randomized complete block design with three replications under two complementary irrigation and dryland condi...

Drought stress is one of the most limiting abiotic stresses affecting growth, production and survival of plants in many areas of the world, and is expected to intensify considering the trend of climate change. Grass species are important for the sustainability of agricultural systems, forage resources for animal farming and landscapes. Grass species adapt to water deficit by different morpholog...
