Problems solved by technology

[0003] At present, the in vitro rapid propagation research of Phalaenopsis plants is mostly concentrated on peony, and there are few domestic and foreign researches on Phalaenopsis tissue culture. There is no complete set of methods for rapid propagation of Phalaenopsis underground buds, nor does it involve the rooting and transplanting of Phalaenopsis tissue culture seedlings, which cannot provide a basis for production

Abstract

The invention discloses a butterfly orchid tissue culturing method. The method comprises the steps of obtaining butterfly orchid stem tips, sterilizing the butterfly orchid stem tips, conducting preliminary culturing and subculturing to the butterfly orchid stem tips obtained after sterilization, and conducting rooting culturing. The method has the advantages that by means of the method, the rooting percentage of butterfly orchid tissue culture seedling plants reaches 26.7% at the maximum; tissue culture seedlings which are generated by the adoption of the stem tips and cultured in an isolated mode are capable of maintaining excellent characteristics of an original variety, so that foundations of elite propagation and industrial production are laid; according to the butterfly orchid tissue culturing method, the operation is simple, the cost is low, and the method is applicable to intermediate propagation of majority of ornamental butterfly orchids.

Description

technical field [0001] The invention relates to plant tissue culture technology, in particular to a method for tissue culture of Phalaenopsis. Background technique [0002] Phalaenopsis aphrodite Rchb. F. belongs to the genus Phalaenopsis Phalaenopsis. It is native to subtropical rainforest and is an epiphytic orchid. The thick white aerial roots of Phalaenopsis are exposed around the leaves. In addition to absorbing nutrients in the air, they also have growth and photosynthesis. In the Spring Festival, the Phalaenopsis plant has long flower stalks from the leaf axils and blooms like butterflies flying. It is favored by flower lovers and is known as the "Queen of the Orchid". [0003] At present, the in vitro rapid propagation research of Phalaenopsis plants is mostly concentrated on peony, and there are few domestic and foreign researches on Phalaenopsis tissue culture. There is no complete set of methods for rapid propagation of Phalaenopsis underground buds, nor doe...
