This study was performed to compare some physiological and molecular responses of lemon balm to osmotic stress imposed by drought and salinity stresses with equal osmotic potential in hydroponic culture. Growing lemon balm plants in hydroponic culture were treated with drought and salinity stress using polyethylene glycol 6000 and sodium chloride for 14 days. Then, seedlings were sampled to eva...

Determining environment – associated alterations in grain yield is important in yield assessment under drought stress. Therefore this study was carried out to determine the correlation coefficients and direct and indirect effects of effective components on yield in four drought - tolerant and susceptible cotton cultivars. Cotton cultivars were considered as sub plots and 3 levels of irrigation ...

Drought stress is considered as one of the most important constraints to the crop production, including medicinal plants in many arid and semi-arid regions. This study was carried out to determine the most effective indices for drought tolerance and identification of tolerance genotypes under drought conditions in N. sativa. For this purpose, 36 genotypes of N. sativa were tested as a split plo...

                      In order to study effect of the various levels of drought and salinity stress (0, -4, -8, -12, -16 bar) on morphological, physiological and biochemical traits of Atriplex halimus in seedling stage under hydroponic culture, two separated experiments were conducted as completely randomized design in three replications in hydroecology laboratory of Gonbad Kavous University...

To evaluate genetic diversity and to determine the relationships between yield and other importante traits among bean genotypes, an experiment was conducted in Random Completely Block Design (RCBD) with three repetitions under both normal and drought stress conditions in 2015-2016 crop season on 30 bean genotypes  at Tehran University research farm. The results of variance analysis indicated hi...

In order to investigate the effect of salicylic acid on photosynthetic pigments, enzyme activity and yield of durum wheat cultivars under drought stress, a greenhouse experiment was conducted as factorial based on complete randomized design with 3 replicates. Treatments included of drought stress in two levels of normal irrigation and drought stress at the beginning of the milking stage, and sa...
