Abstract: In order to explore adaptive mechanisms of Artemisia frigida in an arid grassland,water content,cell membrane permeability,malondialdehyde(MDA) content,and protective enzyme activities for a pot culture were studied using natural arid processing with soil relative water content being determined. Results showed that the leaves of A. frigida had low water loss,superoxide dismutase (SOD) activity first increased and then decreased,catalase (CAT) activity first decreased and later increased,MDA content was steady,and in the early stage of drought stress(0 - 8 d after not wartering,with soil water content > 6.5%) membrane system damage was slight. With increasing time and drought stress,SOD,CAT,and peroxidase(POD) activity decreased,MDA increased,and membrane systems were seriously hurt. To the twelfth day with soil water content being 2.7%,all leaves permanently wilted. Thus,with drought stress,SOD and CAT played an important role in cleansing reactive oxygen.[Ch,5 fig. 13 ref.]
