多效唑是一种赤霉素生物合成阻滞剂,在油菜生产中已广泛应用于油菜壮苗的培育,效果十分显著。油菜幼苗期喷施多效唑,能干扰阻碍植株体内赤霉素合成,降低生长素吲哚乙酸含量,诱导和促进脱落酸细胞分裂素的合成,从而改变植株体内激素平衡,实现在激素水平上有效地调节植物生长发育,促进植株生理形态指标向有利于高产的方向转化。多年的生产实践证明,多效唑用于油菜生产的培育壮苗,具有见效快、效果好、持效期长的特
Paclobutrazol is a gibberellin biosynthesis blocker, which has been widely used in the cultivation of rapeseed seedlings in rapeseed production, the effect is very significant. Seedlings of rapeseed spraying paclobutrazol can interfere with the inhibition of plant gibberellin synthesis, reduce the content of auxin indole acetic acid, induce and promote the synthesis of abscisic acid cytokinin, thereby changing the plant hormone balance in the hormone level to achieve effective Regulate the growth and development of plants, and promote the plant morphological indicators to facilitate the direction of high-yield transformation. Years of production practice has proved that paclobutrazol for the cultivation of seedlings strong rapeseed production, with quick, good effect, long lasting special
