摘要
目的:研究独一味在原生地的开花特性与传粉方式对传粉效率的影响。方法:通过对独一味花序开花方式、单花组成及特性、传粉方式及传粉效率、散粉及花粉特性及柱头沉积花粉数的研究,探讨独一味传粉有效方式。结果:独一味花序为轮伞花序密集排列而形成的穗状花序,同一花序中有10%"L"型和90%"S"型2种异型花柱;单花为两性花,花器官由萼片、花冠、雄蕊、雌蕊组成;盛花期的花序中有蚂蚁、熊蜂等昆虫活动,风媒传粉能力弱。结论:独一味传粉效率最高的方式依次为自花传粉,同株自花传粉,异株异花传粉能力较弱。
Objective：To study the pollination efficiency of blossom characteristics and pollination mode for Lamiophlamis rotata.Methods：Through the inflorescence of Lamiophlamis rotata flowering patterns,composition and properties of a single flower,pollination and pollination efficiency,study on the number of pollen and pollen characteristics and stigma pollen deposition of Lamiophlomis rotata effective pollination mode.Conclusion：The spike from round umbrella inflorescence of Lamiophlomis rotata.The spike make up 10%long-styled morph and 90%short-styled morph;flower organ consists of sepals,corolla,stamen and pistil.In full bloom flower has the insects such as ants,bumblebee,weak wind pollination,Results：Pollination efficiency are in turn：self-pollinating homologous strain self-pollinating〉different strains cross pollination.
