摘　　要：测定了8种不同地域铁皮石斛的株高、茎粗、叶面积和叶长宽比等农艺性状及其含水量、总多糖、水溶性多糖和纤维素含量.结果发现存在农艺性状的地域差异,其中雁荡品种和云南品种株形中等,茎较粗,多糖含量较高,是适于浙江省推广的品种之一,但浙江引种云南品种时必须大棚种植.Some agronomic characteristics such as height, stem diameter, relative leaf area and leaf length breadth ratio and components such as water content, total polysaccharide, water-soluble polysaccharide, and cellulose contents of 8 kinds Dendrobium officinale from different distribution areas were determined and analyzed. It was found that the differences among these agronomic characteristics have to some extent related to where they are from. Dendrobium officinale from Yandang and Yunnan areas which have moderate plant morphology and robust stem are better then that in other areas for planting in Zhejiang, but for Dendrobium officinale from Yunnan, the greenhouse is nessesary.
