| Abstract: | Net photosynthetic rates, chlorophyll contents, root activities and contents of nitrogen, phosphorus, potassium and sugar in shoot of five varieties of Di (Mi scanthus Sacchari-ftorus (Maximi) Benth.et Hook. f. ) have been determined and compared. The results shaw that Pong Je Di and To Je Di were superior significantly over the rest varieties in the physiological indexes mentioned above. In addition, they utilize nitrogen, phosphorus, potassium more efficintly, and contain soluble sugar less than did the rest during growing season. These characterastics favor biological mass increase, and may be used as physiological indexes for selecting good varietics of Di. The experiment shaw that the content of sugar in rhizoma during winter is important in sprouting and growth of Di seedlings in spring. |
