| 摘 要： | 以黄瓜为受体，研究了银杏、毛白杨、油松、杨树、法桐、泡桐6种行道树落叶提取物对黄瓜的化感作用。结果表明：6种行道树落叶提取物对黄瓜均具有化感作用，但化感作用性质、作用强度各不相同。6种行道树落叶提取物对黄瓜苗高表现为促进作用，而对发芽率和干质量无作用|银杏、毛白杨、油松对根长表现为促进作用，杨树为抑制作用，法桐无作用，泡桐则为促进/抑制双重作用|银杏、毛白杨对幼苗鲜质量表现为促进作用，其他叶片无作用。根据综合敏感指数，行道树落叶化感作用强度银杏＞毛白杨＞法桐＞油松＞泡桐＞杨树|黄瓜各性状敏感性苗高＞鲜质量＞根长＞干质量＞发芽率。

| Abstract: | In order to provide the theoretical foundation of street tree leaf-litter’s usage in the production of vegetables,the allelopathy of leaf-litter on cucumber(Cucumis sativus L.)of 6 kinds of street tree(ginkgo biloba,populous tomentosa,pinus tabulaeformis,poplar,platanus orientalis and paulownia)was investigated by means of bioassay in laboratory.The results showed that the leaf-litter of 6 street trees all have allelopathy on cucumber,but their allelopathic mechanisms and intensities were different.The 6 street trees’ leaf-litter could increase cucumber seedlings’ height,but had no effect on their germination rate and dry weight.As for the root length,leaf-litters of ginkgo biloba,populus tomentosa and pinus tabulaeformis had promotion effect,that of poplar had inhibit effect,platanus orientalis had no effect,and paulownia had promotion/inhibit double effects.The leaf-litters of ginkgo biloba and populus tomentosa could increase the fresh weight of cucumber seedlings,but that of the other 4 had no effect.The comprehensive sensitive index reflects that the allelopahy of ginkgo biloba>populus tomentosa>platanus orientalis>pinus tabulaeformis>paulownia>poplar,the sensitivity of seedling height>fresh weight>root length>dry weight>germination rate. |
