摘要
采用培养皿滤纸法研究了入侵植物——加拿大飞蓬各个器官水浸提液对水稻和油菜的种子萌发及根长的影响.研究结果表明,加拿大飞蓬各个器官水浸提液均对受体植物种子最终萌发及根长产生了不同程度的抑制作用并延缓了受体植物的萌发速率.
The allelopathic influence of water extraction of invasive plant Erigeron canadensis L. was investigated. The water extraction was applied to Oryza safiva L. and Brassica campestris L. to test the number of the germinated seedings and the length of the root of the receptors. The results showed that the invasive plant. Canadensis L. inhibit the receptor＇ s seedlings germination and length of root, and delayed the germinations.
