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，提高了ＰＯＤ活力。

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 decre...
