摘要
再生稻在热带和亚热带产稻国都有种植,并为水稻科学家所关注。本世纪30年代,四川农学院杨开渠教授首先对再生稻作了系统研究。70年代南方稻区对再生稻的研究深入到品种再生力的遗传与选育,腋芽的形态、生育特点、营养生理、促芽肥施用时期和数量。
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 cor-relation with diurnal mean temperature and humidity after harvest.(3)The number of sprou-ting 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.
