三个C两优杂交稻组合的株型及干物质生产特性
Plant Type and Dry Matter Production Characteristics of C Liangyou Hybrid Rice Combinations
摘要
Abstract
The plant type and dry matter production characteristics were studied by using three C Liangyou hybrid rice combinations as materials and Shanyou 63 as a control. Comparing to Shanyou 63, the C Liangyou hybrid rice combinations showed narrower and longer uppermost three leaves, narrower leaf angles and larger total leaf area; maintained stronger root vigor and higher net photosynthetic rate and contents of chlorophyll at the full heading stage; had shorter and wider base internodes and stronger lodging resistance, longer middle internodes, and a long uppermost internode occupying 42.77％ of total stem length;displayed more photosynthate accumulation and greater transportation ability. The dry matter exportation and dry matter accumulation in stem and leaves after heading significantly and positively correlated with the grain yield for the C Liangyou hybrid rice combinations. Ideal plant type, stronger dry matter production and transportation ability at the middle and late growth stage are the main cause leading to high yield of the C Liangyou hybrid rice combinations.关键词
