摘　　要：刺萼龙葵是一种外来恶性杂草,在我国境内的传播对现有的生态系统构成严重威胁。刺萼龙葵对环境条件的广泛适应能力增强了其竞争优势,使其发展成为一种高度危险的外来入侵杂草,控制刺萼龙葵的危害和扩散蔓延已变得越来越重要。文章综述了刺萼龙葵种子的形态特征和休眠机制,总结了种子萌发特性和打破种子休眠的一些方法,为制订其综合防控策略提供科学依据。Buffalobur（Solanum rostratum Dunal） was a vicious foreign invading weed specie,spreading poses a serious threat to the native existing ecosystems in China.Buffalobur increased its competitive advantage by wide adaptation to the environment,and developed itself into a highly dangerous invasive weed.It had been increasingly important to control the infestation and spreading.Seed morphologic character,seed dormant mechanism,methods for seed germination and dormancy-breaking were introduced in this paper,which would provide scientific guidelines to integrated strategies for protecting and controlling of this specie.
