报道了云南省一新记录的外来植物--西亚大蒜芥(Sisymbrium orientale L.).该物种在澳大利亚入侵农田、草场,在我国虽已有分布记录,但未见到相关预警性研究报道,目前为止尚未引起重视.西亚大蒜芥种子细小,易随风传播,具有形成大面积扩散的潜力.本次调查发现该物种在云南昆明有扩大分布的趋势.建议对该物种在我国的分布进行全面调查,查清其分布状况和入侵途径,并进行种群动态监测,适时清除,避免不必要的入侵发生. |

A alien plant species, Sysimbrium orientale L. (Brassicaceae) is recorded in Yunnan, China in the paper. The species has been found invading the ecosystems of croplands and grasslands in Australia. Although it was previously recorded in China, there's no alert report about it. Because the very small and mass-produced seed in siliques was dispersed by wind, the species can be potentially invasive. The result of our investigation indicated that there was a spreading trend of S. orientale in suburbs of Kunming, Central Yunnan. The biological characteristics and current status in Kunming were reported. We appealed to relevant government departments to make efforts to make a further investigation of its distribution and its invasion route. Assessment of its invasiveness in China is needed to eradicate it as early as possible to avoid its diffusion. |
