在大田试验和盆栽试验条件下,对不同株型品种的叶面积与干物质生产速度,消光系数和穗型与群体光分布,叶绿素含量、比叶重和含氧量的品种间差异及其与产量性状的关系,气孔密度和气体扩散阻力的类型间、品种间差异及其与光合速率的关系,源库关系等问题进行了广泛的、综合的研究,旨在从水稻生理学角度阐明高产水稻品种应具备的株型特点及选育理想株型品种应注意的问题。1 不同株型品种的冠层特征与干物质生产
Under field and pot experiment conditions, the differences of leaf area and dry matter production rate, extinction coefficient and light intensity of panicle and population, chlorophyll content, specific leaf weight and oxygen content in different plant varieties were studied. Yield characteristics of the relationship between the stomatal density and gas diffusion resistance types, the differences between varieties and their relationship with photosynthetic rate, source and the relationship between the library and other issues a comprehensive and comprehensive study aimed to clarify the rice physiology from high-yielding rice varieties Should have the characteristics of plant type and selection of ideal plant type should pay attention to the problem. Canopy Characteristics and Dry Matter Production of Different Plant Types
