摘要
用磁感应强度为0.5、1.0、1.5和2.0T的磁场分别处理黄瓜萌动种子5和10min,结果表明,幼苗体内超氧化物歧化酶、过氧化物酶、苯丙氨酸解氨酶活性都比对照组明显提高,且黄瓜霜霉病的病叶率和病情指数都显著低于对照,表明磁场可以通过清除植物体内自由基和提高植物酚类次生物质合成代谢等增强黄瓜幼苗对霜霉病菌的抗性。
With the magnetic induction intensity of 0.5T, 1.0T, 1.5T and 2.0T magnetic field dealt with separately germinat- ing seeds of cucumber 5min and 10min. Results showed that seedlings of superoxide dismutase （SOD）, peroxidase （POD）, phenylalanine ammonia-lyase （PAL） that more active than the control group was significantly increased, and the diseased leaves of cucumber downy mildew rate and disease index were significantly lower than the control. Indicating that the mag- netic field through the removal of plant free radicals and improve the synthesis of secondary metabolites of plant phenols such as enhanced metabolism of cucumber seedlings to downy mildew resistance.
