摘　　要：目的:收集和保存鼓槌石斛种质资源,为筛选优良种质奠定基础材料。方法:采用文献查阅、访问和实地调查相结合的方法,对鼓槌石斛种质资源的分布、植物学性状及利用现状进行了调查,并对种质进行了收集。结果:野生鼓槌石斛种质资源在植物形态上如茎的大小、叶的形状、花唇瓣的颜色等方面存在明显差异,近10年来,调查地区鼓槌石斛野生资源蕴藏量严重下降。结论:野生鼓槌石斛种质资源生物学存在多样性,其中不乏高产种质资源。Collected and preserved germplasm resource of Dendrobium chrysotoxum to lay the foundation for screening fine germplasm.Through refering literatures,visiting and field survey to investigate the distribution,botanic characters and apply status of D.chrysotoxum,furthermore to collect the germplasm resource.The result show that wild germplasm resource of D.chrysotoxum has obvious differences in stem characters,leaf shape as well as flower color aspects.In addition,in recent ten years,the reserves of D.chrysotoxum germplasm resource seriously descended.Through this study,we can draw a conclusion that D.chrysotoxum germplasm resource exist diversity in biology.In these germplasm resource,there are high yield and good quality variety.
