this research was investigated to study relationship among seed yield, seed yield components and morphological traits and their direct and indirect effects on seed yield of 100 safflower genotypes in two water environments (normal and drought stress) at research farm of isfahan university of technology during 2012. seed yield had positive correlation with number of head per plant, seed per head...

Abstract This study was conducted to evaluate the role of oxidative stress in roots of eight wheat genotypes with different drought tolerance, subjected to drought stress. For analyzing the changes of antioxidant enzymes, native PAGE analyses of protein extract were performed. The roots of wheat seedlings showed one unambiguous isoform of superoxide dismutase (SOD) and catalase (CAT). Eight iso...

heat stress is one of the main obstacles for crop production in many areas of the world including southwest of iran. in order to evaluation the effect of heat stress on yield, yield component, and mopho-phenological traits of wheat, an experiment was conducted during 2010-2011 under normal (optimum sowing date) and heat stress (late sowing date) conditions on 11 wheat genotypes including yavaro...
