| 摘 要： | 选取广林桉9号叶组织作为供体,绿豆、水稻、芥菜、油菜为受体,运用室内培养皿生物测定方法研究了桉树叶水浸提液的化感作用。结果表明:桉树叶水浸提液对绿豆和水稻种子萌发的抑制作用不明显,但对受体植物芥菜和油菜种子的化感作用达显著的水平。桉树叶水浸提液对4种受体植物的根长和苗高均有一定的抑制作用,且抑制作用随着浓度的增大而加强。桉树叶水浸提液处理使4种受体植物幼苗丙二醛(MDA)含量增加,但其根系活力却明显降低。

| Abstract: | In order to study the allelopathic effect of water extract of Eucalyptus leaves,the germination rate and germination index of Vigna radiate,Oryza sativa,Brassica juncea,Brassica campestris were tested with aqueous extracts of Eucalyptus leaves by adopting indoor petri-dish bioassay.The results showed that the water extracts of Eucalyptus leaves inhibited significantly the germination of Brassica juncea and Brassica campestris,but had no strong effect on Vigna radiate and Oryza sativa.The extract inhibited t... |
