摘要
水稻的株型育种问题在我国已有一些研究,近年来各地又育成了一批株型较好的新品种,如沈农1033、桂朝2号、献党1号、赣化2号、皖稻1号、南粳35等。有关不同株型的水稻光合特性和粳稻叶型遗传的研究国内也有过报道。作者在对株高、分蘖习性及经济性状研究的基础上,本文着重报道水稻叶型的类别及其与光合作用的关系。
The leaf types of rice includes two characteristics:leaf area and leaf angle with main culm.The leaf area is divided into three types,while the leaf angle is divided into six types.They are mainly controlled by genetic factors.Different leaf types have different effects on photosynthesis and out put.Generally speaking,the leaf area index and the weight of dry matter above ground during grain filling,leaf thickness and the vertical extent of flag leaf all have significam correlations with the output.
