title: [Effects of soil factors on active component content of Chrysanthemum morifolium].
abstract: OBJECTIVE
  To study the effects of soil factors on the active component content of Chrysanthemum morifolium and screen out the leading factors.
  
  
  METHODS
  The active component of water soluble extracts, flavonoids, phenolic compounds and mineral elements were determined and chemical properties and mineral elements of soil were analyzed for studying the effects on Ch. morifolium through correlation, stepwise regression, path and grey correlation analysis.
  
  
  RESULTS
  Soil available P and K were the most important factors that affected the active component content of Ch. morifolium, followed by urease, phosphatase and invertase activities and organic matter. The mineral elements in Ch. morifolium and in soil correlated well, P and K were enriched in the plant mostly, followed by Cd, Ca, Zn, Cu. The main leading factors of mineral elements in soil were P and K, followed by Fe, Cu and Zn.
  
  
  CONCLUSIONS
  Soil was one of the important factors which affected the active component content of Ch. morifolium.
