摘要
弯喙苣属(Urospermum)有2种,原产于南欧、北非和西亚。其中,该属的模式种弯喙苣(Urospermum picroides(L.)Scop.ex F.W.Schmidt)目前已在北美洲、南美洲、澳大利亚、南非和巴基斯坦等许多地区归化,我国曾有引种栽培,近来成为宁波地区一种新的归化杂草。本文就弯喙苣的分类地位、形态特征、地理分布、生物学特征、传播途径、入侵危害、防治措施进行了报道,以期为外来有害杂草的鉴定提供借鉴。
The genus Urospermum is native to South Europe,North Africa and West Asia,including 2 species.Urospermum picroides(L.)Scop.ex F.W.Schmidt is the type species of this genus.It has been naturalized in North and South America,Australia,South Africa and Pakistan.It had been introduced and cultivated in China,and recently become a new naturalized weed in Ningbo,Zhejiang Province.In this paper,the taxonomic status,morphological characteristics,geographical distribution,biological characteristics,dispersal routes,invasion hazards,control measures were presented to provide evidences and data in detail in species identification.
