摘　　要：刺萼龙葵(Solanum rostratum)为茄科茄属有严重危害的有毒植物,原产于北美。在美国被列为有害杂草,在加拿大被列为入侵植物,在俄罗斯和我国被列为境内限制传播的检疫杂草。该植物于1981进入我国辽宁,继而在北京出现,如今首次在乌鲁木齐被发现,说明它的潜在入侵区包括干旱区。文章阐述了刺萼龙葵的主要形态特征、分布与生境、化学成分及功效、危害、进化生物学、在中国入侵危险性评价等方面的研究进展,分析了其在乌鲁木齐出现的生态学意义,提出了有待研究的科学问题,旨在为防止其在干旱区传播蔓延及其开发利用提供参考。Solanum rostratum is a prickly annual of the nightshade family and is considered noxious on farms and rangelands. It is a native North American species. It was found firstly in Liaoning province of China in 1981 and was found in arid region-Urumqi of Xinjiang in 2006. This paper previews advances on its description, distribution and habitat, compound and their roles, pollination ecology and potential fatalness invade to China. The paper analyzes the ecological significance appeared in arid region in China and proposed some scientific questions to resolve for the species.
