Storage Carbohydrate Accumulation and Transportation Pattern of High Yielding Colony of Hybrid Rice

  • Storage carbohydrates(SC)accumulation and transportation pattem in high yielding colony of hybrid rice appeared as Logistic curve with the highest accumtilation speed at flowring stage.Among storage carbohydrates, the starch assumulation trends also appeared as Logistic curve with the highest accumulation soeed at earlier stage of milk mature, However,the accumulation trends of monosaccharides and oligosaccharides appeared as single kurtosis curve with the highest accumulation amount at heading stage From initative panicle differentiation to heading,a lot of SC waS accumulation in vegetative organs especially in sheaths and stems After heading the SC ws transported to panicles,which composed 30%~33% of the SC accumulated in grains.Most of transportable SC was transportion to panicles in ten days after heading,which was about the half of seed SC accurnulated in the same period.Under the production condition of Longhai City,the SC accumulation of earlier crop hybrid rice was higher in sheaths and stems before heading and form leaf photosynthesis after heading Therefore,the grain yield of earlier crop rice showed greatly higher than that of later crop rice.
