RESUMEN
OBJECTIVE: To lay foundation of strains selection through primary selection of 44 strains of Lycium barbarum. METHODS: Used the single plant selection. RESULTS: Screened out 22 strains of Lycium barbarum by preliminary determination of germination rates and seeding rates of hardwood cutting, the growth potential of 2009-26, 2009-21, 2009-17, 2009-29, 2009-2 were better than those of others strains. CONCLUSION: 2009-26 has better growth potential except the length of root, the result provides a basis for further screening can focus on research for 2009-26.

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. CONCLUSION: 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.
