摘要: 试验用场强为1000GS、1400GS、1800GS的磁场处理番茄(Lycopersicon esculentum Mill)种子,于子叶期和真叶期进行低温胁迫,发现处理组超氧化物岐化酶(SOD)比活性和过氧化氢酶(CAT)活性均高于对照组。子叶期幼苗谷胱甘肽(GSH)和可溶性蛋白含量与对照相比均有所升高。幼苗外观寒害症状也较轻。因此,可以认为磁场处理在一定程度上可提高番茄幼苗的抗寒性。

Abstract: The tomato seedlings, of which the seeds were treated by magnetic field, at both cotyledon and euphylla stage exposed under the same lower temperature with different time durations.The result showed that when the seedlings were treated by magnetic field the activity of SOD and CAT as well as the content of GSH and soluble protein in cotyledon seedling were higher than the control.Therefore, the chilling injury symptoms of treated seedlings were alleviated.

Key words: Tomato seedling, Magnetic field, Chilling stress, Protective enzyme.
