Abstract: In this study, the wild Tetrastigma hemsleyanum Diels et Gilg wild species FJ-WYS and the cultivar Huaiyu 2 were selected as the research object to study the differences in photosynthetic characteristics, chlorophyll fluorescence parameters, chlorophyll content, leaf length, leaf width and leaf type index. The results showed that the intercellular CO2 concentration (Ci), steady-state fluorescence (Fs), chlorophyll content (SPAD), leaf length and leaf type index of Huaiyu 2 were significantly higher than those of FJ-WYS, while the stomatal limit value (Ls), water use efficiency (WUE), net photosynthetic rate (Pn), instantaneous carboxylation rate (CUE), minimum initial fluorescence (Fo) and leaf width of FJ-WYS were significantly higher than those of Huaiyu 2. The photosynthesis of Huaiyu 2 was weaker than that of FJ-WYS, and there was no positive correlation between photosynthesis and chlorophyll content and leaf type index.

Key words: Tetrastigma hemsleyanum Diels et Gilg., photosynthetic characteristics, chlorophyll fluorescence
