title: [Growth and photosynthetic characteristics of Ardisia corymbifera var. tuberifera in bionic wild cultivation].
abstract: OBJECTIVE
  To explore the growth dynamic and photosynthetic characteristics of Ardisia corymbifera var. tuberifera in bionic wild cultivation.
  
  
  METHODS
  The test of bionic wild cultivation was conducted with two-year-old seedlings as well as three-year-old cuttings of Ardisia corymbifera var. tuberifera, and their growth dynamic and photosynthetic characteristics were studied.
  
  
  RESULTS
  Both seedlings and cuttings of Ardisia corymbifera var. tuberifera maintained good growth in imitation of the wild, the height were increased by 9.2 cm and 12 cm, base diameter were increased by 2.48 mm and 2.39 mm,and crown width were increased by 10.6 cm and 17 cm, respectively. Two-year-old seedlings branched only once a year, and three-year-old cuttings branched thrice a year. There were no significant differences in all photosynthetic parameters of the two kinds of seedlings, and the range of growth light intensity of Ardisia corymbifera var. tuberifera was wider. Owing to the weaker light quantum efficiency under lower light and relatively lower light photosynthetic capacity under higher light, its competition ability was lower in the field.
  
  
  CONCLUSIONS
  The increases of height and crown width were greater in cuttings than those in seedlings, and the transplanting survival rate of the former was larger.
