Selective culture process of nasturtium

Abstract

The invention provides a selective culture process of nasturtium. The culture process form of traditional roxburgh anoectochilus terminal buds is broken through, embryos of picked fruits are obtained,and the embryos are placed in a culture medium to be cultured to obtain rooting seedlings; the first-stage color species selecting is conducted on the rooting seedlings, and the root seedlings with yellow leaves are selected as first-stage target seedlings; the second-stage color species selecting is conducted on the first-stage target seedlings after the seedlings are cultured for a period of time, and at least one first-stage target seedling with the most yellow leaves is selected as a second-stage target seedling; then, the second-stage target seedling is cultured until flowering and fruiting happens, fruits are picked after getting ripen, the embryos of the picked fruits are obtained, and the nasturtium with a plurality of golden yellow leaves is cultured through the embryos; or cellculture is conducted on the second-stage target seedling, and the nasturtium with a plurality of golden yellow leaves is obtained. Compared with the prior art, the efficient and stable nasturtium species culturing can be conducted.

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 clematis is known, and as Chinese invention patent, CN103782905B discloses a kind of Clematis clematis field selection and breeding method, and its concrete steps comprise: 1) the selection of explant [0003] Between September and November every year, when clematis blooms, we select wild and robust clematis that have bloomed and have excellent traits. 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 operating table, open the fruit pods, and put the seeds inside Inoculate on Aurea aureus culture medium; 3) Culture step Place the...

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 (the golden clematis of golden yellow leaves), and in fact, golden clematis has a high medicinal value. and easier to be recognized in the market
