摘　　要：研究了油橄榄叶水提物和醇提物对双子叶植物番茄和牧草,以及单子叶植物玉米、小麦和草坪种子萌发的影响,分别测定了茎长、根长、茎重、根重、发芽率和发芽势。结果表明,油橄榄叶提取物对不同种子萌发影响有差异,与溶剂种类、提取物浓度、种子类型有关;油橄榄叶提取物对根的抑制作用比茎强;低浓度提取物对种子萌发有促进作用,高浓度提取物对种子萌发有抑制作用;油橄榄叶有水溶性生物碱和醇溶性生物碱,分别对不同种子萌发表现不同的效应。In this paper, sendies were made of the effect of both aqueous extracts and ethanol extracts of olive leaves on the seed germination of tomato, grass, corn, wheat and lawn, and the determination was conducted on the length and weight of stems and roots, the germination potential and germination rate. The results showed that extracts had different influences on various seeds. These influences were related with solvent types, extract concentration and seed species. The roots were inhibited much more than the stems. The low concentration extract would promote the seed germination however the inhibition would occurr with the high concentration extract. Both soluble alkaloid and alcohol-alkaloid were found in olive leaves, and they exhibited different effects on various seeds.
