[Objective] The research aimed to explore the effects of drought stress on the activity of the antioxidation protective enzyme in the seedlings of Lycium barbarum L.and provide theoretical basis for the water-saving irrigation of L.barbarum.[Method] The potted seedlings of L.barbarum were treated with different degrees of drought stress,and the membrane permeability,the content of soluble protein,the activity of superoxide dismutase(SOD),the oxygen evolution rate and the content of membrane-lipid superoxide...
