Effect of glutathione and/or selenium levels on growth, yield, and some biochemical constituents of some wheat cultivars grown under sandy soil conditions

Abstract

The results indicate that the Gemmeiza-11 cultivar was the most adapted cultivar to grow in the Nubaria region. Individually, glutathione at 300 mg/l or selenium at 10 mg/l caused the highest significant increases in shoot dry weight/plant of three wheat cultivars relative to other levels. Likewise, glutathione treatment at 300 mg/l was the optimum treatment in increasing photosynthetic pigments in three wheat cultivars. Selenium treatment at 10 mg/l was better than selenium treatment at 5 mg/l. Interaction between glutathione at 300 mg/l and selenium at 10 mg/l caused the highest significance increases in total photosynthetic pigments. It is obvious that glutathione at 300 mg/l or selenium at 10 mg/l as individual treatment showed the highest significant increase in grain yield (ton/fed).
