摘要
头季稻齐穗后１５天施用赤霉素既可增加头季稻产量，又可增加再生稻产量，增产的原因是头季稻的穗粒数、千粒重和再生稻的有效穗的提高。外源赤霉素改变了内源激素的含量和相互间的平衡，延缓了根叶衰老。
GA3 applied on main crop rice 15 days after full heading can increas the grain yield of bothmain and ratoon crops because GA3 improves the balance of endogenous hormones which delays the senes-cence of leaves and roots, resulting in the increase of the number of spiklets per panicle and 1000 grainweight of main crop rice and the increase of the number of productive panicles per unit area of ratoon crop rice.
