摘要: 探讨了在水稻始穗期用云大-120水剂、赤霉素、三十烷醇3种植物生长调节剂处理不育系Ⅱ-32-8A对杂交水稻制种产量的影响,结果证明该不育系在喷施赤霉素后效果最好,能使每667m2产量比对照提高43.16%,异交结实率比对照提高23.06%,千粒重比对照增加1.16%。

Abstract: This paper discusses the effect of the three Growth Regulotors——Yunda-120, GA3 and Triacontanol to treat the sterility strain Ⅱ-92-8A at the starting spike stage on the hybrid seed yield of Hybrid Rice. The results indicate that the GA3 effects are best. It is to make the yield increase 43.16% and the crossing rate of grains 23.06%. The weight of 1000 grains increases 1.16%.

Key words: PLANT GROWTH REGULOTORS, HYBRID RICE, HYBRID SEEDS YIELD, EFFECT
