To probe into the role of GST in water stress,GST activities in the seedlings of common centipede grass ( Eremochloa ophiuroides ) treated by PEG6000 are investigated.The results show that H 2O 2 and GSH accumulated, and the ratio of electrolyte leakage increased.GST activities in the seedlings treated by PEG are higher than that of CK, and increased gradually with elongation of stress time. The changes of GST activities have a postive correlation with the acculumlation of H 2O 2( r =0.868) ,which suggests that GST may not only clean...
