effects of salinity on growth and germination of wheat embryos

ABSTRACT

Selected genotype of wheat [Triticum aestivum L] progeny line W4909 [salt tolerance] was used In this study. Wheat embryos were grown and subjected to different concentrations of NaCl [0,50,100,150 and 200 mM] in Gzapek Agar [GZ] solid media. The results shown that total length, fresh weight and water content of wheat seedling decreased as the NaCl concentrations increased. Dry weight and total protein content also increased in wheat seedling that exposed to moderate [100 mM] and severe [150 mM] NaCl stress respectively. Furthermore, protoplasm desiccation appeared in the cells of wheat seedling that grown up to 150 mM Nad It can be concluded that embryos of progeny lines W4909 was tolerant to NaCl stress and were grown successfully in salty media up to 150 mM NaCl even thought the seedlings show a decrease in growth parameters
