摘要
研究了不同时期环割对红地球葡萄果实发育期叶片光合特性的影响。结果表明,环割处理不能改变红地球葡萄果实发育期叶片光合特性受果实发育时期(季节)影响的趋势,且不同时期环割处理和对照处理的叶片光合参数差异不明显,只是在果实发育后期(采果前)环割枝条上叶片净光合速率、气孔导度显著降低。
The effect of girdling on photosynthetic characteristics of leaves of Hongdiqiu grape at different stages of fruit growth was studied in this paper. The results showed that girdling treatment could not change the variation (caused by seasonal changes) of photosynthetic characteristics of leaves during the fruit development, and the photosynthetic parameter of leaves between the girdling treatment and the control treatment showed no obvious differences, except in the late stage of fruit development (before picking) , the net photosynthetic rate (PN) and stomatal conductance (Gs) of the leaf on the girdled branch significantly reduced.
