| 摘 要： | 1 引 言Hg是环境污染的重要因素,有关Hg对植物生长发育的影响及危害机制已有报导1,3],但Hg对玉米种子萌发作用尚未见报道.种子萌发依靠自身储存的淀粉、脂肪和蛋白质的分解来提供物质和能量,合成新的生命物质.因此环境对种子萌发的影响首先表现在对这些大物质分解代谢的影

| Abstract: | The study shows that seed soaking with HgCl 2 can decrease the germination rate of maize, inhibit the growth and respiration intensity of its seedling, and the activities of aminotransferase, diastase and lipase in endosperm and those of diastase and lipase in seedling during the process of germination. Low concentration of HgCl 2 can promote maize growth. |
