摘　　要：以沙培培养的方法,叶面喷施蒸馏水为对照,分别设置2种浓度赤霉素和脱落酸叶面喷施处理,研究了赤霉素和脱落酸对甜菜幼苗保护酶活性的影响。结果表明,叶面喷施适宜浓度赤霉素和脱落酸可促进甜菜幼苗叶片和根SOD、POD、APX,以及根CAT活性,进而提高甜菜幼苗抗逆能力。Experiments were conducted to study the effect of two concentrations of GA and ABA by foliar spray under sand culture on protective enzyme activities of sugarbeet with water as control. The results show that： foliar sprays with optimal concentrations of GA and ABA increase the activities of SOD, POD, APX in leaf and root, and activities of CAT in root. These may improve stress tolerance of sugarbeet seedling.
