Although safflower is widely distributed in Iran, other diversity centers have also been reported in many Asian and European countries, especially arid regions of the world. In this research 15 domestic and 42 exotic safflower genotypes were evaluated for drought tolerance in three locations of Najafabad (Isfahan), Jiroft and Jopar (Kerman), using a lattice design at normal and drought stress c...

  This study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. Different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. Genotypes were sown under normal irrigation and moisture stress conditions. In stres...

Drought stress is one of the most important abiotic stresses in crops that can reduce yield and yield components in terms of time, duration and severity of the stress. Current research was carried out in order to evaluate drought stress tolerance in rice genotypes. Experiment done in two separate schemes using randomized complete blocks design with three replications in Research Field, Faculty ...
