Tissue culture and rapid propagation method for variation malus spectabilis

Abstract

The invention discloses a tissue culture and rapid propagation method for variation malus spectabilis, and belongs to the field of plant tissue culture and propagation. The tissue culture and rapid propagation method has the advantages that processes for explant selection and disinfection, primary culture, secondary culture, rooting culture, transplanting and the like in variation malus spectabilis tissue culture are provided, accordingly, the contamination rate of the variation malus spectabilis tissue culture and the death rate of tissue culture seedlings due to improper handling can be reduced, and the variation malus spectabilis tissue culture efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of plant tissue culture and breeding, and in particular relates to a tissue culture rapid breeding method of mutated winter red fruit. Background technique [0002] Donghongguo is a deciduous small tree of the Rosaceae apple genus. The leaves and veins are green, the flower color is light pink, it blooms in spring, and it bears fruit immediately. The fruit is clustered, and the fruit color is green at first, and then turns yellow. After late autumn, the leaves fall off. From February to March of the second year, it is also called longevity fruit, so it is of high ornamental value. At the same time, the plants are relatively short and the tree shape is compact, which is very suitable for viewing as bonsai, suitable for indoor and outdoor placement, and is deeply loved by the masses. Winter red fruit propagation generally uses apple seedlings as rootstock grafting, and it can bloom and bear fruit in the second year. ...
