摘要
研究了水杨酸对大豆(Glycinemax)合丰25号、合丰35号幼苗生长过程中盐伤害的缓解效应及其可能机制。结果表明,水杨酸能够提高盐胁迫条件下大豆苗期根系性状,提高幼苗相对含水量及可溶性蛋白含量;使SOD、POD的活性增加,相对电导率降低。同时,两品种上述指标的测定结果表明,合丰35号在各项指标上均好于合丰25号,尤其在抗盐性和水杨酸对其缓解作用方面,合丰35号优于合丰25号。
Responses of Hefeng 25 and Hefeng35 （Glycine max） to salt stress-induced injuries were studied during the seedling growth stage. The results showed： under salt stress, Salicylic acid can increase the root characteristics in seedling stage, increase relative water content and dissolved protein content in of seedling, promote the activity of SOD and POD, decrease the relative rate of conduct. Meanwhile, the result were showed by testing data, Hefeng 35 is better than Hefeng 25, especially on the characters of resistant salt and mitigative effect of Salicylic acid.
