引言对于水稻的光合作用与干物质生产,国内外研究颇多,其中以户苅和武田等的论述较为系统、完整。本文以我国常规稻和杂交稻的推广品种为材料,探讨了水稻生育期中光合速率变化的规律和不同品种光合产物的生产和分配的特点。 INTRODUCTION There are many studies at home and abroad on the photosynthesis and dry matter production of rice, among which the accounts of households and land are more systematic and complete. In this paper, the varieties of conventional rice and hybrid rice in China were used as materials to investigate the regularity of photosynthetic rate changes during rice growth and the characteristics of photosynthate production and distribution in different varieties.
