摘要 以皇嘉牌油菜素内酯、防落素对菜豆进行处理,探索它们对花荚脱落作用的影响。结果表明:150mg/kgHJNBR和35mg/kgPCPA均能对菜豆前期花荚脱落有明显的抑制作用,且150mg/kgHJNBR更能显著提高菜豆的总产量,但其对豆荚的生长速度并无显著的促进作用,对单荚重也无明显影响。即使用皇嘉牌油菜素内酯(HJNBR)使菜豆产量增加的原因主要是由于增加了菜豆的座荚率。 Took HJNBR and PCPA as treatments, and studied their effects on the drop of bean flowers and pods. The restilts showed that: HJNBR with 150 mg/kg and PCPA with 35 mg/kg could obviously control the drop of flowers and pods in prophase, and HJNBR with 150 mg/kg could significantly improve the bean yield, hut which had not significantly improved the growth rate and the single-pod weight. That was to say, the reason that improved the bean yield through the application of HJNBR was the improvement of bean pod rate.
