In many plants, glycine betaine acts as an osmotic protectant and osmolyte. But some plants, such as the tomato, are not able to synthesize and accumulate this osmolyte. This study was designed to investigate the effect of exogenous application of glycine betaine in reducing drought stress in tomato plants. Water stress in three levels (0, 3 days and 5 days without irrigation) and glycine betai...

Breeding for environmental stress is one of the most important goals in plant breeding. Among stresses, drought stress has high influencing on limitation of maize production. Therefore, in order to find the best drought tolerant hybrids, 38 maize hybrids were planted in two separate experiments: one with optimum irrigation (control) and another with water stress at grain-filling stage in Moghan...

four rapeseed cultivars (hayola 401, hayola 308, rgs and option) were evaluated for some physiological traits under stress (50 % field capacity (fc) and non-stress (irrigated) conditions. the factorial set of treatments was arranged within a randomized complete block design with three replications. the collected data were analyzed using path and factor analyses. these is results showed that bas...

  Abstract In order to evaluate morpho-physiological traits of confectionery sunflower under different irrigation regimes, an experiment was carried out under field conditions in Agricultural Research Center of West-Azerbaijan province, Urmia, Iran in 2012. Fifty six confectionery sunflower landraces were arranged in 7 × 8 rectangular lattice design with two replications in each one of well-wat...
