| 摘 要： | 研究了不同浓度Hg2 、Cd2 、Pb2 、Cr2 处理对甘蓝型油菜黔油12号、黔油14号、黔油18号叶绿素含量的影响。在Hg2 、Cd2 、Pb2 、Cr2 胁迫下,随着重金属浓度的增加,处理时间的延长,油菜叶绿素总量有下降趋势。三个油菜品种中,黔油18号对重金属耐受性最强,黔油14号耐受性最差。

| Abstract: | The present article studies influences of Hg2 ,Cd2 ,Pb2 and Cr2 of different density on the chlorophyll content of cabbage-typed Qian rape No.12,14 and 18.Under the press of Hg2 ,Cd2 ,Pb2 and Cr2 ,the gross amount of the chlorophyll in rape has the decreasing tendency with the density of heavy metals increasing and handling time longer.Of three rape varieties,Qian rape No.18 has the strongest resistance against heavy metals,and No.14 the weakest. |
