title: [Effects of different light quality on growth, active ingredients and enzymes activitiesof Salvia miltiorrhiza].
abstract: OBJECTIVE
  This study aimed to investigate the effects of different light quality on the growth, accumulation of active ingredients and enzymes activities of Salvia miltiorrhiza.
  
  
  METHODS
  The seedlings of S. miltiorrhiza were treated by different light quality, and relative parameters were measured. The data was statistically processed.
  
  
  RESULTS
  Plant height was significantly decreased with supplemental blue light (WB), and the root length, root diameter, root fresh weight and root dry weight were significantly increased with supplemental red light (WR). Salvianolic acid B concentration in S. miltiorrhiza was highly increased by supplemental blue and red light, but tanshinone IIA concentration was not significantly affected by supplemental blue and red light. Enzymes activities of SOD, POD, PAL, TAT and PPO in S. miltiorrhiza were significant increased by supplemental blue light, and enzymes activities of POD, TAT and PPO were significant increased by supplemental red light.
  
  
  CONCLUSIONS
  The root growth of S. miltiorrhiza was greatly promoted by supplemental red light (WR). Salvianolic acid B concentration in S. miltiorrhiza was highly increased by supplemental blue and red light. Enzymes activities of TAT and PPO in S. miltiorrhiza were significant increased by supplemental blue light and red light.
