[Method] Through applying different concentrations of taurine(0, 10, 100, 500, 1 000, 5 000 mg/L), the photosynthetic rate(Pn), stomatal conductance(Gs), and the activities of membrane protective enzymes superoxide dismutase(SOD) and peroxidase (POD) in the treated L. bararum seedlings were measured. [Result] Treatment of proper taurine concentration could to some extent enhance Pn and increase the POD and SOD activities, and meanwhile decreased the Gs and MDA content. And the optimum application amount of taurine was determined to be 500 mg/L. [Conclusion] Proper concentration of taurine has protective effects on the cell membrane of L. bararum seedlings.展开更多
