杂交早稻库源关系特征与其调控途径研究

STUDY ON THE SINK-SOURCE RELATION AND REGULATION IN THE EARLY-HYBRIDRICE

本文探讨了杂交早稻的库源关系特征,指出在不同群体条件下库源关系是变化的.在一般栽培条件下杂交早稻是库源互作型,小群体条件下为库限制型,而大群体条件下则是源限制型.分析了杂交早稻库源关系的调控途径.

Features of sink-source relation in the Early-Hybid Rice was studied.It is pointedout that the relation of sink-source changes under different community conditions.Theconclusion is that the Early-Hybrid Rice belongs to the type of sink-source reaction underthe condition of common cultivation,but it belongs to the type of sink-limitation under thecondition of small community and the type of source-limitation under the condition oflarge community.A relgulation way is then approached.
