摘要
目的:探讨活性氧对五味子雌花/雄花比例的影响,为五味子栽培提高产量奠定基础。方法:在花芽分化前期喷施不同浓度的H2O2、百草枯、连二甲亚硫酸钠溶液。结果:连二甲亚硫酸钠可使雌花/雄花比例由7.6%提高到42.3%,而H2O2、百草枯作用不明显。结论:不同的活性氧载体物质对五味子雌花/雄花的比例调控效果不同,连二甲亚硫酸钠溶液喷施五味子叶片效果最好。
Objective：To study the effect of reactive oxygen species on female-male flower ratio of Schisandra chinensis in order to improve the yield. Methods：Spraying different concentration solution of H2O2, paraquat and sodium dithionite on the leaves of Schisan- dra chinensis before fruit bud initiation. Results：Exogenous sodium dithionite（ O2- carrier）increased the female-male flower ratio greatly from 7.6% to 42. 3%. H2O2 and paraquat（ OH- carrier）had little effect. Conclusion：The regulation effects vary according to different ROS. Exogenous sodium dithionite has the best effect.
