摘要:
以1 a生格木幼苗为试材，研究分析了生根粉6号（GGR-6）、赤霉素（GA3）、萘乙酸（NAA）3种植物生长调节剂在不同浓度梯度（0（CK）、5、15、25、35、45 mg/L）下，对格木幼苗根系活力、总根长、总根表面积、根平均直径和总根体积的影响。结果表明：3种植物生长调节剂对格木幼苗的根系生长发育均有显著的促进作用，其中GGR-6的促进作用最为显著，GA3次之，NAA的促进作用最低，且3种植物生长调节剂对格木幼苗根系生长发育的影响都是随着植物生长调节剂浓度的不断升高而呈现出先增大后减小的变化趋势。
Abstract:
Choosing one year old Erythrophleum fordii seedlings as experimental materials，the effects of the three plant growth regulators with different concentrations（0（CK）、5、15、25、35、45 mg/L） on the root activity，total root length，total root surface area，root diameter，and root volume of Erythrophleum fordii were analyzed.The results showed that compared with CK，GGR-6，GA3 and NAA had distinctly simulative effect on the root growth of Erythrophleum fordii  seedlings.Among them，the simulative effect of GGR-6 was the most obvious，GA3was the second，and NAA was the minimum.Furthermore，as plant growth regulator concentration increased，the growth of root showed first increased and then decreased trend.
