Abstract: Jatropha curcas is one of important raw materials of biological diesel oil.The seed germination and growth of rape, fodder grass and wheat treated with the solution extracted from the seeds of Jatropha curcas were investigated to study the effects of mass cultivation of Jatropha curcas on the environment and the growth of plants.The results showed that the water solution from Jatropha curcas seeds reduced the germination percentage of seeds, the length of buds and the length of roots of these three crops.Most alcoholic extracts could reduce the germination percentage of seeds, the length of buds and the length of roots of fodder glass and wheat.But some alcoholic extracts at specific concentration could promote the growth of rape buds.

Key words: seeds of Jatropha curcas, extract solution, crop seed

摘要： 研究不同浓度的小油桐籽水提取液及酒精提取液对‘贵杂110号’油菜、‘卓越’黑麦草及‘早麦10号’小麦种子萌发及幼苗生长的影响。结果表明,小油桐籽水提取液对3种作物种子发芽率、幼苗的芽长及根长有抑制作用,且随浓度提高抑制作用增强;酒精提取液对黑麦草与小麦的种子发芽、幼苗芽和根的生长有抑制作用,但特定浓度可促进油菜幼苗芽的生长。
