水杨酸浸种对小麦种子萌发生理生化指标的影响

摘要

In order to get more effective application for salicylic acid in wheat production,the effect of salicylic acid (SA) soaking on wheat seed germination physiology biochemistry target was studied.The results showed that the various physiological biochemistry target of wheat seed sprouts had the change,the hyperoxide mutase(SOD) activeness,the peroxide enzyme(POD)activeness and the polyphenoloxidase(PPO)activeness rised,the malondialdehyde(MDA)content dropped.%为使水杨酸在小麦生产应用中得到更有效的应用,研究了水杨酸(SA)浸种对小麦种子萌发生理生化指标的影响.结果表明:小麦种子萌发各生理生化指标均有变化,超氧化物歧化酶(SOD)活性、过氧化物酶(POD)活性和多酚氧化酶(PPO)活性均上升,丙二醛(MDA)含量下降.
