A kind of seed selection and cultivation technology of golden lotus

Abstract

The invention proposes a seed selection and cultivation process of golden lotus, which breaks through the traditional cultivation process of golden clematis, obtains the seed embryos of the picked fruits, puts the seed embryos in culture medium and cultivates them to obtain rooted seedlings; In the first stage of color variety selection, a plurality of rooted seedlings with yellow leaves are selected as the first-order target seedlings; after a period of time, a plurality of first-order target seedlings are cultivated for color variety selection in the second stage, and the leaves are selected. At least one of the yellowest first-stage target seedlings is used as the second-stage target seedling; then the second-stage target seedlings are cultivated until they bloom and bear fruit, and they are picked when the fruit is mature, and the seed embryos of the picked fruits are obtained, and then passed through multiple seedlings. The golden lotus with multiple golden yellow leaves is cultured from the embryo; or the cell culture is carried out on the second-stage target seedling to obtain the golden lotus with multiple golden yellow leaves. Compared with the prior art, the invention can carry out high-efficiency and stable cultivation of golden lotus varieties.

Description

technical field [0001] The invention relates to the field of plant cultivation methods, in particular to a process for seed selection and cultivation of golden lotus. Background technique [0002] The cultivation method of clematis is well known, such as Chinese invention patent, CN103782905 B discloses a method of field selection and breeding of clematis, and its specific steps include: 1) selection of explants [0003] Between September and November every year, when clematis blooms, we select wild clematis that have bloomed and have excellent characteristics, and after artificial pollination, fruit pods are formed; plump, unbroken fruit pods are picked As an explant; 2) Aseptic operation of the explant After cleaning the picked fruit pods, perform aseptic operation. After disinfecting the outside of the fruit pods in the aseptic operation table, open the fruit pods and put the seeds inside Inoculate on Aurea aureus culture medium; 3) Culture steps Place the inoculated exp...

AI Technical Summary

Problems solved by technology

[0004] The golden clematis seedlings cultivated by this invention can improve the survival rate, but it is similar to other cultivation methods on the market, and it cannot cultivate golden clematis (a golden clematis with golden yellow leaves). and easier to be recognized in the market
