桉树叶水浸提液对4种植物种子化感作用的生物测定
Bioassay of Allelopathic Activity of Water Extract of Eucalyptus Leaves on Seed Germination of Different Kinds of Plants
摘要
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 the growth of the roots and stems of four receptor plants, and the inhibition exhibited concentration dependence.Some physiological and biochemical indices of the treated receptor plants indicated that water extract of Eucalyptus leaves increased the MDA contents, and remarkably reduced the root vigor.关键词
