Abstract
Rice and tall fescue(TF) were treated with 50mM and 150, 200mM NaCl, respectively, under light intensity of 130μE and 500μE. Growth of both plants was not different between NaCl and NaCl+BSO treatments. Na and Cl contents of TF were increased in 200mMNaCl+BSO treatment with 500μE. GSH content of rice in NaCl treatment was lower with 500μE than with 130μE and that of TF was increased in 200mMNaCl treatment with 500μE. TBARS content of rice was higher with 500μE than with 130μE and BSO did not affect or increased it in both plants. The difference between GSH and total-GSH contents of rice in NaCl treatment with 500μE was larger than that in control and TBARS content was maintained at the same level, suggesting that GSH might work as a scavenger of ROS. But there is a possibility that TBARS level might not be high enough to disturb the plant growth.
