Variation of protective enzyme activity of Atriplex canescens and Ceratoides lanata under water stress
SOD, CAT and MDA of Atriplex canescens and Ceratoides lanata were measured under water stress. The results indicated that the activity of SOD and CAT of A. canescens increased under water-stress, but decreased in C. lanata. MDA contents of both species increased with the increasing stress, but A. canescens had higher MDA than C. lanata. The increase of SOD and CAT activity with prolonged stress in A. canescens reduced its MDA content, which prevented the plant from O2- harm and increased its drought resistance and gave 98. 35% survival rate, while C. lanata only had 61. 20% viability. The result could be used as reference to selecting adapted forage species to dry desert region in northwest.
