摘　　要：以花生幼苗为试材,研究3种植物生长调节剂赤霉素(GA)、水杨酸(SA)和丁酰肼(B9)在不同浓度梯度(0、0.001、0.010、0.100、1.000、10.000 mg/L)下,对花生幼苗植株及根系的影响。结果表明,不同浓度的3种植物生长调节剂能够促进花生幼苗植株及根系的生长发育,其中B9处理的效果最为显著,0.100 mg/L为最佳处理浓度。SA次之,1.000 mg/L为最佳处理浓度。GA最低,0.010 mg/L为最佳处理浓度。在对花生幼苗植株及根系生长发育的影响上,3种植物生长调节剂的作用效果有一定的规律性,即随着浓度的提高而表现出促进效果由大变小的变化趋势。Choosing peanut seedlings as experimental materials,the effects of the three plant growth regulators with different concentrations(0,0.001,0.010,0.100,1.000,10.000 mg/L)on the peanut seeding plants and roots were analyzed.The results showed that compared with CK,GA,SA and B9 had distinctly simulative effect on peanut seedings and roots.Among them,the simulative effect of B9 was the most obvious,0.100 mg/L was the best treatment concentration.SA was the second,1.000 mg/L was the best treatment concentration.GA was the minimum,0.010 mg/L was the best treatment concentration.As the concentration of plant growth regulators continued to increase,the effects of plant growth regulators on the growth of peanut seedlings and roots were firstly increased and then decreased.
