title: [The comparative study on morphology and polysaccharides content of Dendrobium loddigesii from different habits].
abstract: The morphological characters and the polysaccharides content of Dendrobiam loddigesii from different habits were studied in this paper. The results showed that there were remarkable differences in morphology from five areas, such as stem height and diameter, laminae sizes and figures, amount of lateral bud, and texture of stem. The content of polysaccharides from sample of Xingyi and Anlong, Guizhou Province, respectively 22. 62% and 20. 96% , were higher than that of other areas. It can be preferentially choosed as good materal on commareial production.
