摘　　要：本文研究了 Pb对五种树木叶片的生理伤害和 L n- Gly- VB6 对 Pb污染胁迫的缓解作用 ,实验结果表明 ,L n- Gly- VB6 能明显减轻 Pb污染造成的植物叶片叶绿素含量下降 ,质膜透性加大 ,过氧化氢酶活性改变 ,Pb富集量上升。说明 L n- Gly- VB6 对Physiological harm to five kinds of evergreen and mitigative effect of Ln Gly VB 6 on them under Pb stress were studied.The results show that the Ln Gly VB 6 obviously mitigative Pb pollution results in decreasing of chloropyll content,rising of catalase(CAT) activity and increasing of Pb content.The experiment proves that the Ln Gly VB 6 have a definite effect on plants from the injury of Pb.
