中国蔷薇科归化植物新纪录——尖齿黑莓

Rubus argutus Link(Rosaceae),a new recorded naturalized plant in China

安徽省滁州市发现中国蔷薇科新记录植物——尖齿黑莓(Rubus argutus Link)。该种原产北美洲,是许多栽培树莓的亲本,目前已在日本、新西兰、夏威夷等地归化,并造成一定的生态危害。尖齿黑莓具有掌状复叶、茎具棱、皮刺极为发达,易与国产悬钩子属植物显著区别。文章调查了其分布面积、提供详细的照片与形态描述,介绍了其生物学特性、危害、价值及国外的防治手段,并就其入侵风险进行讨论。凭证标本保存于安徽师范大学生命科学学院植物标本馆(ANUB)。

Rubus argutus Link(Rosaceae),found in Chuzhou,Anhui Province,is a newly recorded plant in China.This species is native to North America and is the parent of many cultivated raspberries.At present,it has been naturalized in Japan,New Zealand,Hawaii and other places,and caused certain harm to ecology.The R.argutus has palmate compound leaves,ribbed stems,and extremely developed prickles,and is easily distinguished from native Rubus plants.The article investigates its distribution area,provides detailed photos and morphological descriptions,and introduces its biological characteristics,hazards,values and control methods,and discusses its invasion risk.The voucher specimens are kept in the Herbarium,College of Life Sciences,Anhui Normal University(ANUB).
