چکیده
Salt stress is a major problem in the corn cultivation, which reduces corn yield quantity and quality worldwide especially in the arid and semi-arid regions. Nuclear technologies can be used as a useful method for mitigating salt stress effect on plants. In the current evaluation, the influence of gamma irradiation (GI) at 25 Gy on corn seeds (SC703) was studied in salt stress amelioration of corn in the field. It was observed that GI increased total chlorophyll content of corn leaves under saline condition. In addition, plants from gamma-irradiated seeds had a greater plant weight, and their economical traits (cob weight and grain number) were higher compared to control plants. Thus, it can be concluded that low dose GI may be able to ameliorate the effect of salt stress on corn plant.
