English Abstract

[Objective] The research aimed to study whether spermidine (Spd) could relieve salt stress on wheat seedling. [Method] The seedlings growth and some physiological indices were determined under exogenous spermidine and NaCl stress by means of filter paper culturing methed. [Result] NaCl stress restrained the growth of seedlings, enhanced SOD and POD activity, increased MDA content, and decreased the amount of soluble proteins. Spermidine apparently promoted the growth of wheat seedlings and raised SOD and POD activities and soluble protein content, but decreased the content of MDA in seedlings compared with the control. [Conclusion] The spermidine could relieve the impairment of NaCl stress in wheat seedlings, thus enhance its tolerance to NaCl. However, the relief effect of spermidine decreased as the treatment lime prolonged.
