摘　　要：采用国际通用营养液配方,以砂培方式研究不同质量浓度硒对粗壮女贞叶绿素、根系活力、SOD、POD、CAT、GR、MDA以及新梢萌芽能力的影响,结果表明:硒质量浓度为1 mg/L时,SOD、POD活性最弱,根系活力最强,可促进粗壮女贞的生长,增强新梢的萌芽能力。而当硒质量浓度大于1 mg/L时,则会起到抑制作用;MDA随着硒质量浓度的增大呈升高趋势,CAT和GR活性随着硒质量浓度的增加而减弱。因此认为适量的硒处理能够增强粗壮女贞的抗氧化能力,提高产量。Effects of different selenium concentrations on chlorophyll, root activity, SOD, POD, CAT, GR, MDA, and embryonic shoot of Ligustrurn robustum, were examined through sand culture studies and international common nutrient solution formula. The resuhs showed that：when the concentration was 1 mg· L^-1 , SOD, POD activity was the weakest, and root activity was strongest to promote the growth of Ligustrum robustum and new shoot sprouting; when selenium concentration was more than 1 mg· L^-1, physiology activity was depressed, and MDA increased, and CAT and GR activity decreased. Our results indicated that selenium treatment on Ligustrum robustum with certain concentrations can accelerate antioxidant capacity and improve embryonic shoot.
