Abstract: Four rice cultivars were used to study the relationship between distribution of assimilation production stored in stubble and ratooning rate of axillary buds and yield characteristics of ratooning rice.The results indicated that:about 52%-70% assimilation production stored in stubble was distributed in ratooning rice.And the distribution proportion in spikes,pedicle sheathes and leaves was more than 27%,14%-26% and 9% or so,respectively;About 46%-61% assimilation production was distributed in the upper second and third nodes of ratooning rice;The proportions in different parts of ratooning rice were positively correlated with ratooning rate of axillary buds,yield and its components of ratooning rice;The proportion in any node of ratooning rice was significantly positively correlated with ratooning rate of axillary buds,yield and its components of the same node of ratooning rice.
