摘要
世界范围内,柳树分类一直是公认的难题。到目前为止,关于柳树的分类系统,没有权威的定论,不同的国家和地区仅存在相对认可的柳树分类系统。笔者总结中国近50年的柳树研究现状,以柳树天然分布、杂交育种现状及跨地域引种驯化等方面为背景,浅谈柳树分类困难的原因,以供讨论。
On a world scale, the classification of willows is a recognized problem. There is still no authoritativeverdict about the classification of willows now, and different countries and regions have their relativelyrecognized classification system. The authors summariz research status of Chinese willows in recent 50 years,and discuss the reasons of the uncertain classification of willows based on their natural distribution, crossbreeding condition and geographical disperse introduction and domestication.
