Study on Photosynthetic Characteristics of Different Grape Varieties

The 10 different grape varieties were used to study the photosynthetic characteristics of grape. The net photosynthetic rate, intercellular CO2 concentration, stomatal conductance, transpiration rate, and leaf temperature of grape leaves were determined by using the Li-6400 portable photosynthesis system in this paper. The results showed that the photosynthetic characteristics of different grape varieties were significant differences. The net photosynthetic rate, stomatal conductance, chlorophyll content of Fujiminori and Victoria were higher than the others. The intercellular CO2 concentration of Fujiminori and Victoria were lower than leading variety in Liangshan.
