Problems solved by technology

Blueberries use single-bud shoots for tissue differentiation and cluster buds. Although cluster buds are relatively easy to cultivate, it is very slow for mass cultivation of blueberry seedlings.
In the 5th issue of "Molecular Plant Breeding" in 2007, Ning Zhiyuan and others used the induction of blueberry cluster buds and plant regeneration, that is, the single bud shoots of young leaves to cultivate blueberry plants. When the concentration of ZT is too high, it will exceed 2.0 mg / L, and will form A large number of adventitious buds, some calluses and vitrified seedlings appear, reducing the number of effective seedlings; in the 9th issue of 2010 "Northern Horticulture", Yu Qiangbo et al. used blueberry semi-quality new slightly to cultivate blueberry plants, which is prone to brown change

Abstract

The invention discloses a culture method for blueberry embryoids. The culture method comprises the steps of preparing a culture medium by using blueberry with 2-3 months old leaves as an explant, preparing a culture medium, sterilizing the explant and inoculating, subculturing calluses, inducing single cells, differentiating the single cells and culturing the embryoids. The calluses of the blueberry are obtained by induction of the blueberry leaves, the calluses are cultured to obtain the single cells, the single cells are induced to the blueberry embryoids, and the blueberry embryoids are used for culturing the blueberry plants, so that the formation of adventitious buds and vitrified shoots can be reduced and the number of effective seedlings. The calluses can be prevented from browning by using PVP, which is very suitable for the calluses of the blueberry. A culture speed is fast, one hundred thousand of blueberry tissue cultured seedlings can be cultured within five months, and the cultured seedlings have similar growing states basically, high plant qualities and relatively small plant viruses.

Description

technical field [0001] The invention relates to a kind of rare fruit variety blueberry embryoid body culture, which belongs to the field of plant tissue culture. Background technique [0002] The use of leaves to induce callus is very common in tissue culture. Blueberries all use single-bud branch to carry out tissue differentiation cluster buds, although cluster buds are easier to cultivate, but this is very slow for mass cultivation of blueberry seedlings. In the 5th issue of "Molecular Plant Breeding" in 2007, Ning Zhiyuan and others used the induction of blueberry cluster buds and plant regeneration, that is, the single bud shoots of young leaves to cultivate blueberry plants. When the concentration of ZT is too high, it will exceed 2.0 mg / L, and will form A large number of adventitious buds, some calluses and vitrified seedlings appear, reducing the number of effective seedlings; in the 9th issue of 2010 "Northern Horticulture", Yu Qiangbo et al. used blueberry semi-qu...
