摘要： 用不同浓度的锌（Zn2+）处理燕麦种子，结果表明:Zn2+浓度高于10-3mol/L时，燕麦种子萌发、种子中α-淀粉酶活性和幼苗根系与地上部生长均受到明显抑制；随着Zn2+浓度的增加，根系活力下降，细胞膜透性增加，硝酸还原酶活性降低，根冠比下降。

Abstract: The oat seeds were soaked in the solution with different concentration of Zinc(Zn2+).The results showed as follows: the oat seed germination, α-amylse and seedling growth wee inhibited when [Zn2+]>10-3mol/L.With increased of Zn2+ concentration, the root activity reduced and cell membrane permeability increased, Nitrate reductase and root shoot ratio reduced.
