Cultivation method for Dendrobium initial species embryo

Abstract

The invention discloses a dendrobe orchid initial embryo breeding method. First, a dendrobe orchid capsule of which the embryo is ripe and the seed pod is indehiscent is collected, washed by 70 percent of ethanol for 1min-2min, then is dipped by 10 percent of supernatant fluid of calcium hypochlorite for 20min, and then washed by sterile water for twice to four times; then the embryo is taken out by cutting the fruit skin; finally the embryo is planted in the sterilized culture medium for culturing. The embryo can be dipped in the sterile water for shaking up, the embryo with water is aspirated by a sterile sucker and evenly dripped into the culture medium in the microsphere way, and the embryo can also be evenly splashed on the surface of the culture medium in a powder shape. The sterile culture medium is adopted to perform sterile insemination to the embryo of the dendrobe orchid, the embryo bourgeons to form a stem and a bud, and then forms a completed plant through multiplication and rootage. The dendrobe orchid initial embryo breeding method has strong operability, simpleness and practicality, fast breeding, small difference among plants and regular seedling.

Description

technical field [0001] The invention relates to a method for cultivating orchids, in particular to a method for cultivating primary embryos of dendrobium orchids. Background technique [0002] Dendrobium (Dendrobium) is the second largest genus in the Orchidaceae (Orchidaceae), second only to Dendrobium in the number of native species, and 81 species (subspecies) have been discovered so far. The global distribution ranges from India, Myanmar, China and Japan in the north to Indonesia, Papua New Guinea, Australia and New Zealand in the south, the Malay Islands and the Philippine Islands. Dendrobium has high medicinal value and ornamental value. As a medicinal material, Dendrobium orchid has medicinal properties such as promoting body fluid, relieving cough, and moistening throat. As an ornamental Dendrobium, it is both beautiful and fragrant, and is a world-renowned flower. [0003] Dendrobium orchids are epiphytic on alpine rocks and trees. In recent years, due to forest ...
