| 摘 要： | 通过水培实验研究了Cu、As污染对作物种子萌发、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，对作物种子萌发时的呼吸强度、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POD活性则随污染物浓度的增加而增加，呈正相关。

| Abstract: | A solution-culture experiment was carried out to explore effects of Cu and As on the germination and seedling growth of crops.The results showed that Cu or As pollution could reduce the activites of protease and diastase,inhibit the seedling growth and the respiration rate of germinating seed of soybean.The inhibition was strengthened with the increase in the concentrations of Cu and As.However,the activity of POD was increased with the concentrations of Cu and As in the exposed solution. |
