摘要: 外域杂草薇甘菊(Mikania micrantha)具有极强的分枝能力。在枝构件水平上,对生长在台湾相思(Acacia confusa)群落和芒草(Miscanthus sinensis)群落中的薇甘菊枝构件的分枝格局和生物量分配的比较分析得出:1)同芒草群落相比,台湾相思群落中薇甘菊各级枝的分枝数、分枝密度和分枝率都低,而分枝长度则较长;2)台湾相思群落中薇甘菊以第一级分枝为主,而在芒草群落中则以第二级分枝为主;3)台湾相思林中薇甘菊枝构件的叶面积率、比叶面积和比茎长及叶片生物量分配显著大于芒草草丛;4

Abstract: An exotic weed Mikania micrantha has an extremely high ability to branch. Based on the shoot module level, a comparative analysis was made on the plant branching pattern and biomass allocation of M. micrantha growing in Acacia confusa community and Miscan
