| 摘 要： | 研究Ｈｇ＾２＋对小麦种子活力、幼苗生长、呼吸及淀粉酶、脂肪酶和转氨酶活力的影响。结果表明，Ｈｇ＾２＋能抑制种子萌发过程中淀粉酶、脂肪酶和转氨酶活性，抑制幼苗生长和呼吸代谢，降低种子活力，但浓度低时，在萌发初期有短暂促进作用。

| Abstract: | This paper deals with the effect of Hg2+ on wheat seed vigour, seedlings growth,respiration rate and activities of aminotransferase, diastase and' lipase during germina-tion. The results showed that Hg'+ could inhibit activities of aminotransferase,diastaseand lipase of endosperm and seedlings,growth and respiration of seedlings during germi-nation,and cut down seed vigor. Low concentration Hg'+, however, had promoter effectof short duration. |
