The trends of absolute increasing rate of LW and absolute expanding rate of leaf area (LA) were represented by positive-negative single-peak curves.

叶片干重的绝对增长速率动态和叶面积的绝对扩展速率动态为正-负单峰型。

Therefore, the photosynthetic rate of grafting plant increased mainly due to expanding total leaf area of melon plant.

因此，嫁接主要是通过扩大植株的总叶面积来提高植株的光合速率的。

The rate of green leaf area decrease was negatively related to increase the well grain-filling grain percentage (PGP) and grain filling degree (GF).

叶面积下降速率与颖花的充实粒率及籽粒充实度呈负相关关系。
