不同葡萄品种光合特性研究

摘要

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.%以10个葡萄品种为材料，用Li-6400便携式光合仪测定葡萄叶片的净光合速率、气孔导度、蒸腾速率、叶温等参数。结果表明：10个葡萄品种的净光合速率、气孔导度、胞间CO2浓度、蒸腾速率、叶温等参数差异显著。藤捻、维多利亚具有较高的净光合速率、气孔导度、叶绿素含量等特性，二者胞间CO2浓度均明显低于当地主栽品种。
