摘要
用２μｍｏｌ·Ｌ－１、５μｍｏｌ·Ｌ－１ＮｉＣｌ２·６Ｈ２Ｏ浸泡早稻“９２１”种子，探讨镍对稻种萌发的影响及生理生化背景．结果表明：镍能有效加快稻种萌发进程、提高萌发整齐度．在浸种早期，镍显著增强种子电解质外渗及ＳＯＤ、ＣＡＴ活力；至浸种后期，镍在降低电解质外渗及ＳＯＤ、ＣＡＴ活力的同时。
The effects of nickel on germination of rice and its physiological and biochemical background was investigated. The results indicated that germination speed was enhanced remarkably by soaking the seeds with 2 μmol·L -1 ,5 μmol·L -1 NiCl 2·6H 2O.At the early stage of soaking, nickel improved SOD,CAT activities and electrolytic leakage; and at the late stage of soaking, nickel improved POD activity remarkably and decreased SOD, CAT activities and electrolytic leakage.
