Photosynthetic matter transportation ratio and filling rate were higher.
光合物质转运率高，灌浆速度快。
2
The relationship of production of population dry matter was strong with the leaf characters such as ratio of leaf weight with leaf area, chlorophyll content and population photosynthetic rate.
比叶重、叶绿素含量和群体光合速率等叶片性状与群体干物质生产密切相关。
