Embodiment Construction

[0014] The present invention can be better understood from the following examples. However, it is easily understood by those skilled in the art that the examples are only for illustrating the present invention, and should not and will not limit the present invention described in detail in the claims.

[0015] From April 2009 to December 2010, in the Tissue Culture Laboratory of the Institute of Crop Science, Shanxi Academy of Agricultural Sciences, after repeated experiments, researchers obtained the tissue culture and rapid propagation technology of Photinia fragrans, and successfully cultivated it into tissue culture seedlings. The main process is as follows: in the morning of a sunny summer day in 2009, collect semi-lignified new shoots as explants, remove excess stems and leaves, put them in a beaker with 0.1% detergent solution, soak for 15 minutes, stir constantly during the period, and put the beaker Cover the mouth with gauze and tie it tightly, rinse with tap water fo...

Abstract

The invention relates to a rapid propagation method of photinia fraseri, which belongs to the technical field of plant culture and comprises five operation steps of: culture medium preparation, explant collection and pretreatment, isolated culture, rooting seedling domestication and transplanting. The transplanting survival rate of the method reaches higher than 90 percent, few explants are adopted, the mother tree growth development and the tree shape culture are not influenced, hundreds of seedlings can be propagated by adopting one terminal bud or stem section, the propagation number can be greatly improved, the scaled and factory seedling is favorably realized, the propagation speed is accelerated, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of asexual propagation of trees, and in particular relates to a rapid breeding method of Photinia fruticosa. Background technique [0002] Photinia fragrans is mostly propagated by cuttings in production. Cuttages generally use branches as propagation materials. The traditional method is to select thick lignified or semi-lignified branches of the year, and cut cuttings about 8-15cm long. The incision is smooth and the upper incision distance The terminal bud is about 1cm, cut off half of the leaves on the top of the strip, and cut off the rest of the leaves. The base of the cut cuttings is treated with a rooting agent and inserted into the substrate to wait for rooting. [0003] First, this method needs a large amount of propagation materials, second, it has a great influence on the growth of the mother tree that is taken, and is unfavorable for tree shape cultivation. Third, it is time-consuming and labor-intensive t...
