| 摘 要： | 通过溶液培养的方法,研究了Cd、Cu胁迫对路易斯安娜鸢尾幼苗生长及生理生化的影响.结果表明:Cd、Cu胁迫下,路易斯安娜鸢尾幼苗生长缓慢,地上、地下干重下降,叶片中的叶绿素含量均随胁迫浓度的增加而降低；植株叶片的丙二醛和游离脯氨酸含量、超氧化物岐化酶活性均随处理浓度、处理时间的延长而增加.

| Abstract: | Iris hexagona were grown hydroponically to examine physiological effects under Cd and Cu stress.The results showed that as the increase of Cd and Cu concentration,the plant growth was put off,the dry weight of shoot and root descent,content of chlorophyll decrease,MDA contents and Pro contents increase,SOD activity increase over time. |
