Breeding method for Chinese Jinxiu yew

Abstract

The invention discloses a breeding method for Chinese Jinxiu yew. The method comprises the following steps of 1 cutting slip collecting, 2 cutting slip treating, 3 seedbed treating, 4 cuttage, 5 final-period management and the like. Before cuttage, cutting wood oil is removed at first, in the cutting slip storage process, no traditional waxing method is adopted, and a specially made nutrient solution is adopted for storage, so that the cuttage survival rate is greatly increased; the nutrient solution is prepared from 0.1-0.25 mg / L gamma-polyglutamic acid, 5-8 g / L of alginic acid, 0-15 g / L of MS culture medium, 5-8 g / L of diammonium phosphate, 0.5-0.8 mg / L of amino-oligosaccharin, 0.05-1.0 g.L of pyraclostrobin, 0.01g / L of polyvinyl alcohol and the balance purified water, wherein all the components account for 1 L. Due to the cuttage method, the survival rate of seedlings of the wild Chinese yew in the Jinxiu county is 95% or above, the survival rate of transplanting after outplanting is 85% or above, and the method has the great value for prolonging the life of precious species resources.
