| 摘 要： | 通过水培实验研究了Cu、As单一及复合污染对黄豆种子萌发、幼苗生长及部分酶活性的影响，结果表明,Cu、As污染明显抑制黄豆种子萌发、幼苗生长，对黄豆种子萌发时的呼吸强度、蛋白酶活性有显著的抑制作用，且随着Cu、As浓度的增加，抑制作用增强，呈负相关；而OD活性则随污染物浓度的增加而增加，呈正相关，Cu、As污染共同存在时，随二者投加比例不同出现不同程度的拮抗效应，可以降低和缓解单一污染物的毒害作用。

| Abstract: | Experiments are carried out with hoagland cultivation to study the effects of Cu and As and their interactions on the germination and seedling growth of Glycine max. The results show that Cu or As pollution reduced proteinase activities,inhibited the seedling growth and the respiration rate of germinating seed of soybean.The inhibition increased as Cu and As concentration increased,POD activities increased with increasing Cu and As concentration.Cu pollution has an antagonistic effect against the pollution of As,and vise versa. |
