Corelationship between the Total Sugar and Nitrogen Contents in Sheaths Plus Culms and Leaf Blades,and the Yields in Early Indica Rice Varieties

Abstract

Key words: stem and sheath, leaf, sugar content, nitrogen content, yield, relationship, rice

摘要： 为了探索品种间一些营养指标与产量的相关性,我们于1981和1982年,选择了分别代表高秆低产和矮秆高产等不同类型的5个早籼稻品种,进行了籼稻在不同生育期内茎鞘和叶片糖氮含量与产量相关性的研究。结果表明，高产水稻在营养生长期植株茎鞘含糖量高，进入生殖生长期后，尤其是齐穗期，功能叶含氮量高，光合力强，产量也较高。早籼稻品种间茎鞘和叶片糖氮含量与产量之间存在相关性。
