摘  要：
为掌握野生葡萄种间和种内不同单株间的光合特性差异,利用Li-6400便携式光合测定系统测定了7种野生葡萄25个单株的光合参数。结果表明:野生葡萄种间光合特性差异明显,美丽葡萄净光合速率最高,其次是刺葡萄,腺枝葡萄的净光合速率最低。野生葡萄种内不同单株间的光合指标多样性丰富,单株间光合特性差异最大的是葛藟葡萄;种内不同单株间原产地气候条件相似,其光合特性差异较小,而原产地气候差异大的单株光合特性差异也大;野生葡萄的光合速率调控机制多样,非气孔因素调控在野生葡萄种群内非常普遍。

摘  要：
In order to acquire the difference among Vitis species and individuals,the photosynthetic parameters of twenty-five lines in seven species were measured using Li-6400 portable photosynthesis system.The results showed that photosynthesis characteristics was significantly different among wild Vitis species,Pn of Vitis bellula was the highest,the second was V.davidii,and V.adenoclada was the lowest.The diversity of photosynthesis indexes among different wild Vitis individuals was abundant.The difference among individuals of V.flexuosa was the biggest.If the climates of origin were similar,the photosynthesis characteristics were alike.If the climates of origin were significantly different,the photosynthesis characteristics were significantly different.The regulation mechanism of Pn was diverse,and the non-stomatal regulation factors were universal in wild Vitis.
