CYTO-CHEMICAL STUDIES ON STORAGE STARCH OF CULM AND RATOON GROWTH IN RATOONING RICE

Liao Jinling and Cao Daming(Agronomy Department)  
Cyto-chemicai studies were made on the relations between the storage starch of culm and ratoon growth in ratooning rice with a lower node position and early maturing strain. The main results were as follows:1. The storage starch that supplies nutrients for ratoon crop was accumulated in culm after the milk stage of the first crop and exhausted about two weeks after harvesting of the first crop.2. The storage starch in the eulm of the first crop could supply nutrients for both bud sprouting and ratoon growth during the initial period of ratoon crop. So the storage starch could promote the growth of stems and leaves and the panicle differentiation of ratoon crop.
