摘    要:对怀牛膝幼苗施加不同浓度的吲哚丁酸(IBA),研究IBA对其幼苗生长及谷胱甘肽抗氧化酶系统的影响.结果显示:1.0mg/L IBA能同时显著提高怀牛膝叶片中谷胱甘肽过氧化物酶(GPx)、谷胱甘肽还原酶(GR)、谷胱甘肽S-转移酶(GST)的活性及蛋白质含量(P<0.05),并能促进其幼苗株高、根长和根干重的增加.结论:1.0mg/L IBA促进了牛膝幼苗的生长,提高了叶片中谷胱甘肽抗氧化酶系统的活性及蛋白质含量,有效的增强了植株的抗逆性.

关 键 词:怀牛膝  吲哚丁酸  谷胱甘肽抗氧化酶系统

Abstract:Objective:To study the effects of Indole-3-butyric acid(IBA)on growth and glutathione antioxidant enzyme system.The results showed that 1.0mg/L IBA treatment significantly improve plant height,root length,root dry weight, protein contents,the activities of glutathione peroxidase(GPx),glutathione reductase(GR)and glutathione-S-transferase(GST).Conclusion:The applying of 1.0mg/L IBA is benefit for the growth and protein accumulation,enhance the activities of glutathion antioxidant enzyme system and improve the resistance of plant.
Keywords:Achyranthes bidentata BL    IBA  glutathion antioxidant enzyme system
