We synthesized nine novel triazole-compounds and investigated their plant growth regulatory activity. Compound CGR3, with methoxyacyl on 3-position of triazole ring, showed better activity, promoting root length not only for mungbean, but also for wheat. Additionally, CGR3 changed the level of endogenous hormones in mungbean roots, the most obvious effect was the increase of IAA, being 4.9 times greater than that of the control at the 96th hour after treatment. Among the synthesized new 1,2,4-triazol derivatives, CGR3 could be applied as a new agrochemical, functioning as a root growth stimulant, which promotes primary root length, influences the levels of endogenous hormones(IAA, ABA and GA3) to play an important role in controlling the primary root development.

作为植物生长调节剂的3,3-二甲基-1-（1H-1,2,4-三唑-1-基）丁酮-2-一衍生物的合成及生物评价

我们合成了九种新颖的三唑化合物，并研究了它们对植物生长的调节活性。化合物CGR3在三唑环的3位上带有甲氧基，显示出更好的活性，不仅提高了绿豆的根长，而且也提高了小麦的根长。另外，CGR3改变了绿豆根中内源激素的水平，最明显的作用是IAA的增加，在处理后第96小时，IAA的增加是对照的4.9倍。在合成的新的1,2,4-三唑衍生物中，CGR3可作为一种新型农用化学品，起着根部生长刺激剂的作用，可促进根部初级长度，影响内源激素（IAA，ABA和GA3）的发挥在控制初生根发育中起重要作用。
