- Abstract
[Objectives] To study changes in SOD, POD, CAT, MAD and Pro content of S. miltiorrhiza Bunge seedlings and the effects of brassinolide (BR) on drought resistance of S. miltiorrhiza Bunge. [Methods] 6 varieties of S. miltiorrhiza Bunge produced in Zhongjiang County of Sichuan Province were used as research object, and the method of PEG-6000 simulated drought stress was applied. [Results] 20% PEG stress 9 d was used as the optimal simulation condition of drought stress. Under the same degree of drought stress, tissue-cultured big leaf S. miltiorrhiza Bunge showed the highest SOD and POD activity, tissue-cultured small leaf S. miltiorrhiza Bunge showed highest CAT activity, long-stalked big leaf S. miltiorrhiza Bunge had lower MDA content than other varieties, and Zhongjiang wild S. miltiorrhiza Bunge had the highest Pro content. [Conclusions] BR can indirectly improve drought resistance ability of S. miltiorrhoa Bunge, and 0.1 mg/L BR has the best action effect.
