[Comparative study of growth potential on hardwood cutting of Lycium barbarum strains].

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.

[Effects of covering on growth potential and chlorophyll content of hardwood cutting of Lycium barbarum].

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.
