Abstract: In order to study genetic relationship of Panax stipuleanatus H. T. Tsai et K. M. Feng groups, the author compared physiological indexes of 2 kinds of leaf Panax stipuleanatus by using conventional free hand section method, spectrophotometry, anthrone method, coomassie brilliant blue G-250 and photosynthesis determinator method. The results showed that the content of soluble sugar in the leaves of full-leaf type was significantly lower than the crenellated type, the full-leaf and crenellated type reached significant level. The starch content in leaves of the full-leaf was slightly higher than crenellated, soluble protein content slightly lower than the crenellated. Differences in the contents of starch and soluble protein were not significant. The crenellated was higher than full-leaf in net photosynthesis rate (Pn), stomatal conductance (Gs), intercellular CO2 concentration (Ci) and transpiration rate (Tr). Full-leaf was higher than crenellated in vapor pressure deficit on leaf surface (VpdL) and water use efficiency (WUE).
