用赤霉酸(GA_3),乙烯利(CPA)、三十烷醇(TRIA)、脱落酸(ABA)、2,4-D 以及6-苄基嘌呤(BA)等激素处理孕穗植株,共处理14份籼稻材料。其中 GA_3和 CPA 对11份材科作了重复试验,证明 GA_3和 CPA 对大部分材料能大幅度提高花培绿苗诱导率,其最适浓度分别为4～7 ppm 和400ppm,但 GA_3、CPA 以及低温预处理,对少数材料的花培诱导有抑制作用。低浓度 TRIA 与 GA_3混合液的处理效果明显优于单独用 GA_3处理的。其它激素除 ABA 有一定作用外,未取得良好效果. The booting plants were treated with hormones such as GA3, CPA, TRIA, ABA, 2,4-D and 6-benzyl-purine (BA) 14 indica rice materials. Among them, GA3 and CPA were tested repeatedly in 11 families. The results showed that GA3 and CPA can greatly improve the induction rate of most cultivars with the best concentrations of 4-7 ppm and 400 ppm, respectively, but GA3, CPA As well as low-temperature pretreatment, the inhibition of flowering induction of a few materials. The treatment effect of low concentration of TRIA and GA_3 mixture was better than GA_3 alone. Other hormones in addition to ABA have a certain effect, did not get good results.
