title: [Regulation on Female-male Flower Ratio of Monoecious Plant Schisandra chinensis Based on Reactive Oxygen Species (ROS)].
abstract: 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 Schisandra 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.
  
  
  CONCLUSIONS
  The regulation effects vary according to different ROS. Exogenous sodium dithionite has the best effect.
