Abstract

The invention relates to asparagus parent breeding method, mainly solving the problems that rooting rate is low, root quality is poor and the survive rate of the regeneration plant is low in asparagus organ tissue culture process. The method includes the process that high quality asparagus stem section is selected, culture is carried out in culture medium solution, and asparagus seedling meeting transplant standard is bred. The culture medium solution is confected by the way that hormones corresponding to various culture stages are added on the basis of the basic culture medium solution, the culture includes induction culture, propagation culture, rooting pre-differentiation culture and rooting culture sequentially. Compared with the existing organ culture, the invention has high propagation rate, rooting rate reaches 100%, root system quality is good, and differentiation rate of strong fleshy tap root is improved to 96%, thus ensuring survival rate after transplantation.

Description

Technical field [0001] The present invention belongs to the field of parental propagation of herbaceous plants, specifically asparagus parental propagation technology. Background technique [0002] The scientific name of asparagus is asparagus, which is a perennial perennial herb of the genus Asparagus in the Liliaceae family. It is a typical dioecious plant. The reproduction of its hybrid parents can only adopt asexual reproduction methods. [0003] The asexual propagation methods of asparagus include the field natural ramification method and the tissue culture method. [0004] The field natural ramification method is to dig out the dormant roots from the field when the parent plants have grown for more than 3 years, divide them into 3 to 5 spore groups according to their natural growth state, and then plant them back in the field to achieve The purpose of proliferation. This method has very low reproduction efficiency and is not suitable for large-scale parental reproduction. [0...
