【摘要】 花蔺Butomus umbellatus L.是北方地区为数不多的挺水观花植物之一,在湿地人工恢复和重建工作中的需求越来越大.目前见于记载的繁殖方式包括有性生殖和通过地下茎进行的无性繁殖,地下茎产生休眠芽体越冬,并有类似禾本科植物的分蘖现象.通过野外观察发现,花蔺的无性繁殖方式除了通过地下茎,夏末花期末期还能在花序轴顶端产生珠芽,通过珠芽也能越冬和繁殖.更多还原

【Abstract】 Butomus umbellatus L.is one of the few emerged flowering plants in north China.In the artificial wetlands restoration and reconstruction work in growing demand.Found in the records of breeding includes sexual propagation and agamogenesis by rhizome.Rhizome has winter-dormant buds.And the tiller phenomenon likes Poaceae.Based on field observations,in addition to the agamogenesis way through the rhizome,but also in the top rachis have bulbils in the end of the summer,the bulbils to breeding and wintering.更多还原
