Abstract
[Objective] The research aimed to study the relationship between spermidine and activities of 3 kinds of antioxidases. [Method] With Yudou 24 (high drought-resistance) and Yudou 6 (low drought-resistance ) as research materials, the effects of PEG,MGBG and exogenous Spd on MDA and Spd contents and activities of 3 kinds of antioxidases (SOD, CAT and APX) in leaf of soybean seedlings under osmotic stress were studied. [Result] Under osmotic stress for 3 d, Spd content in seedling leaf of Yudou 24 increased obviously, MDA content of in seedling leaf of Yudou 6 increased obviously and the activities of 3 kinds of antioxidases in seedling leaf of Yudou 24 increased. MGBG treatment promoted the rise of MDA content in Yudou 24 and inhibited the rise of Spd content and antioxidases activities, but had little effects on Yudou 6. Exogenous Spd treatment increased Spd content and activities of 3 kinds of antioxidases in seedling leaf of Yudou 6 and inhibited the rise of MDA content, but had little effects on Yudou 24. [Conclusion] Under osmotic stress, exogenous Spd could reduce MDA content and alleviate the damage of active oxygen.
