title: [Nutrient change in Lonicera macranthoides during cutting propagation process].
abstract: OBJECTIVE
  To study the dynamic change of nutrient in the cuttings of Lonicera macranthoides.
  
  
  METHODS
  In the process of growing, soluble sugar, starch, soluble protein, total nitrogen and total phosphorus in the leaves and basal of cuttings were determined.
  
  
  RESULTS
  The relationship between nutrient dynamic change and rooting was as follows: the content of the soluble sugar and starch in leaves and basal of cuttings was firstly decreased then increased. The soluble protein in leaves was also firstly decreased then increased, and in basal of cuttings, it showed a downtrend, it decreased slowly at the later stage. The total nitrogen content in leaves and basal showed a downtrend and decreased slowly later. The C/N ratio in leaves and basal of cuttings was firstly decreased then increased. The trend of total phosphorus in leaves was firstly decreases and then increases, and in basal of cuttings, it decreased gradually.
  
  
  CONCLUSIONS
  There exists close relationship between the adventitious root formation nutrients level, and main nutrients play an important role in regulating formation of adventitious root.
