腺柄凤仙花，中国凤仙花属一新归化种

Impatiens glandulifera (Balsaminaceae), A Newly Naturalized Alien Species in China

摘要:

报道了我国漠河城郊发现的凤仙花科凤仙花属新归化种：腺柄凤仙花（Impatiens glandulifera Royle）。腺柄凤仙花原产于印度及西喜马拉雅山脉，是一种具有高度入侵性的一年生草本植物，已经入侵欧洲和北美的许多地区，目前发现已经归化于黑龙江省大兴安岭地区漠河市。调访得知该种至少于两年前人为引入种植，种植1 a后即可通过种子在周边繁殖大量个体。报道了腺柄凤仙花的形态特征、地理分布、生物学特征、传播途径、入侵潜力及危害和防治措施，以期为外来入侵物种的鉴定与防治提供数据支持。

Abstract:

Impatiens glandulifera Royle, an annual species native to India and West Himalayas, has invaded rapidly in many regions of Europe and North America. It was found to be naturalized newly in Mohe City, Heilongjiang Province, China. This species might have been introduced as an ornamental at least two years ago, and would produce large numbers of offspring by seed after one year of planting. The morphological characters, geographical distribution, biological habit, invasive hazards, and control methods were presented for species identification and control.
