title: [Effects of covering on growth potential and chlorophyll content of hardwood cutting of Lycium barbarum].
abstract: OBJECTIVE
  To study the effect of plastic film covering, straw covering, plastic film covering in greenhouse and no-covering cutting on growth and Chlorophyll content of Lycium barbarum hardwood cutting seedlings.
  
  
  METHODS
  Single factor randomized block design method was used in this research.
  
  
  RESULTS
  The effect of different covering treatments on germination rate, seedling rate and growth potential were all plastic film covering in greenhouse > plastic film covering > straw covering > no-covering cutting. Chlorophyll a, Chlorophyll b, Chlorophyll a + b content and Ca/Cb were significantly different with different coverings in different periods.
  
  
  CONCLUSIONS
  The optimal covering on hardwood cutting of Lycium barbarum is plastic film covering in greenhouse. Both plastic film and straw covering are better than no-covering cutting.
