摘　　要：试验以津春4号黄瓜(Cucumis sativus L.)为材料,用高活性腐植酸液剂和Na Cl处理黄瓜种子,研究Na Cl胁迫下腐植酸对黄瓜种子萌发的影响。结果表明,适宜浓度的高活性腐植酸液剂提高了黄瓜种子的发芽率、发芽势、发芽指数、活力指数、胚根长、下胚轴长、胚根中超氧化物歧化酶(SOD)、过氧化物酶(POD)活性,降低了丙二醛(MDA)的含量;其中高活性腐植酸600倍稀释液作用效果最佳。Jinchun No.4 cucumber was used as the test material, the seeds were soaked with different concentrations of high active humic acid under Na Cl stress, the effect of different high active humic acid on germination of cucumber seed were discussed. The results showed the high active humic acid of suitable concentration could increase the germination percent,germination energy, germination index, vigor index, radicle length and hypocotyl length, superoxide dismutase（SOD） and peroxidase（POD） activity, and decrease the content of malondialdehyde（MDA）; The optimal effects could be obtained when the high active humic acid was diluted 600 times.
