title: [Effects of climate factors on quality of Chrysanthemum morifolium originated from Wenxian county].
abstract: OBJECTIVE
  To study the effects of climate factors on the Chrysanthemum morifolium originated from Wenxian county (i. e "huaiju") for assuring the quality of medicinal C. morifolium.
  
  
  METHODS
  The content of water-soluble extracts, protein, sugar, flavonoid and chlorogenic acid of "huaiju" collected from Henanwenxian, Jiangsunanjing and Zhejiangtongxiang were selected as the indicator and determined, climate data of the corresponding places were collected for studying the effects on "huaiju" quality through path analysis and correlation analysis.
  
  
  CONCLUSIONS
  There existed no obviously differences among the detected indicators except the soluble sugar content. Sunlight, temperature and precipitation showed more effects on quality of "huaiju", the sunlight had the most direct effect on flavonoid, the 10 cm ground temperature had the most direct effect on chlorogenic acid.
