Abstract: This paper indicates:(1)The extension of axillary bud of vagina has a close relationshipwith light intensity before harvest.(2)The sprouting of axillary bud has a significant correlation with diurnal mean temperature and humidity after harvest.(3)The number of sprouting seedlings of axillary bud shows a significant positive correlation with the number ofeffective ears of ratooning rice.The amour of sprouting seedlings is the main limiting factorfor the unstable yield of ratooning rice between years and regions.
