“926”植物生长调节剂的药效作用及机理研究

试验表明，“９２６”植物生长调节剂对植物种子活力、根系活力、植物生长发育具有明显的促进作用。用“９２６”浸稻种和玉米种，可提高发芽势、发芽率，增加次生根数和次生根长。苗期施药，同样可促进幼苗生长发育、促进根系发育、增加分蘖、分枝，提高成穗率。其它生育期施药，可分别提高成稳率、穗粒数、粒重，显著提高作物产量。

Studies on the Action of the Medical Effect And the Mechanism of the 926-Plant Growth Regulator

The tests showed that 926-plant growth Regulator had an obvious promoting effect upon seed and root system activity and plant growth and development. After "926" was used to soak rice and corn seeds, the germination potential and germination nate increased; the amount and length of secoday roots increased. if "926" was used in seedling stage, the gorwth and development of plantlet and roots system were promoted; the tiller and ramification and effective rate of ear were increased.If "926" was used in diffennt growth stages, the effective rate of ear and ear granule number, granule weight and yield were increased respectively.
