檵木与红花檵木的解剖结构研究

对7个不同地点的野生檵木、野生红花檵木、栽培红花檵木花的解剖结构进行了研究,浏阳大围山野生檵木花的数性遗传结构与其它地区的野生檵木有较大差异,4数性花和5～6数性花各占50%;红花檵木野生和栽培类型均以5数性花数量居多,不同于文献记载的檵木属植物4数性花的分类属征(每朵花花瓣、雄蕊、退化雄蕊及萼片均为4数).利用花的结构遗传变异探讨了红花檵木的起源和品种演化历史.

Study of the Dissected Structure of Loropetalum chinense and Loropetalum chinense var.rubrum

Study of the wild Loropetalum chinense,wild Loropetalum chinense var.rubrum and cultivated Loropetalum chinense var. rubrum in seven different places.The number genetic wild Loropetalum chinense is different from the other place.The flower 4 and 5-6 are account 50?ch.The wild and cultivated Loropetalum chinense var. rubrum's flower is always five,which is different from the record of the document about the Loropetalum's flower is four(the flower petal,stamen,degenerated stamen and the sepal are also 4).The essay studies the origin and the evaluated history of the variety of the Loropetalum chinense var. rubrum by studying the generation and variation of the flower structure.
