不同葡萄类型光合特性的对比研究初报

Preliminary study on photosynthetic characteristics of different types of grapes

本文以腺枝葡萄、刺葡萄、毛葡萄、夕阳红、金星无核、红宝石无核为试材,运用LI-6400便携式光合作用测定系统测定了5个葡萄种类品种的净光合速率、气孔导度、胞间二氧化碳浓度、蒸腾速率等,结果表明:腺枝葡萄的净光合速率比普通栽培品种夕阳红要高,且不表现"午休现象"。腺枝葡萄在光合性能方面比葡萄栽培品种具有更优越的表现,可以作为高光合育种材料。

Based on the V.adenoclada Hand.-Mazz,Vitis davidii,Vitis heyneana,Sunset Red,Venus Seedless,and Ruby Seedless as experimental materials,LI-6400portable photosynthesis was used to measure net photosynthetic rate,stomatal conductance,intercellular CO2concentration,and transpiration rate of five varieties.The results showed that the net photosynthetic rate of V.adenoclada Hand.-Mazz was higher than common cultivated varieties Sunset Red,and without'lunch break'.V.adenoclada Hand.-Mazz was superior to other grape cultivars in photosynthetic performance and could be used as the breeding materials with high-light.
