title: [Analysis of growth dynamics of Curcuma wenyujin].
abstract: OBJECTIVE
  To study the accumulation of matter and dynamic of chemical compositions in rhizoma of Curcuma wenyujin for its cultivation.
  
  
  METHODS
  The weight of various parts and chemical composition content of rhizoma were determined at regular time.
  
  
  RESULTS
  The growth of Curcuma wenyujin could be divided into the seedling period, the rhizoma growing period and dry matter accumulating period. In seedling period, the aerial parts were the center of organism, the matter accumulated mainly in leaves; In rhizoma growing period, the organic center were gradually transformed from the aerial parts to the underground parts. The tendency of total chemical composition quantity in rhizome presented rises at first but gradually dropped at last.
  
  
  CONCLUSIONS
  The growth of Curcuma wenyujin has two organic centers, the seedling period and the rhizoma vegetal and weighted period. The total chemical composition quantity in Curcuma wenyujin rhizome reaches the maximum value from the last third part of October to mid-November.
