烯效唑(S—3307)是80年代初期继多效唑之后新开发的植物生长调节剂,其生理机制是干扰植物体内赤霉素的合成,具矮化植株、缩短节间作用和提高植株抗倒伏性,本研究着重探讨烯效唑对杂交早晚稻的生长作用及应用技术。
Uniconazole (S-3307) is a newly developed plant growth regulator following paclobutrazol in the early 1980s. Its physiological mechanism is to interfere with the synthesis of gibberellin in plants. It has the advantages of dwarfing plants, shortening the internode effect and increasing plant lodging resistance In this study, we focused on the effects of uniconazole on the early-late hybrid rice growth and its application technology.
