A method of using pseudobulbs to induce plant regeneration and propagation of shixiantao plants

Abstract

The invention belongs to a rapid propagation method for an important plant material in endangered wild plants and particularly relates to a method for inducing a Chinese pholidota herb plant to regenerate and propagate by using pseudobulbs. The method comprises the steps of material selection and sterilization; inducing culture; multiplication culture; inducing rooting; and transplanting. The method aims at solving the problems of seed germination difficulty in a natural state, poor natural propagation capacity, poor diffusion propagation capacity, natural regeneration difficulty, low division propagation speed and the like in the prior art, and provides the technical support for large-scale industrial production. By using the method, the propagation coefficient and the rooting rate are high, the plant growth time is short, the adaptability after culture is strong, a nursery stock is robust and straight, good in growth vigor, neat and consistent, the culture processes of the nursery stock are greatly shortened, and the cost is greatly reduced. The technical support is provided for protecting Chinese pholidota herbs and large-scale industrial production, popularization and application.

Description

technical field [0001] The invention belongs to a method for rapid propagation of important plant materials in endangered wild plants, in particular to a method for inducing regeneration and propagation of shixiantao plants by using pseudobulbs. Background technique [0002] Shixiantao ( Pholidota chinensis Lindl. ) is a plant of the orchidaceae genus Pholdota, also known as stone olive, stone peach and stone lotus. Perennial epiphytic herb, fleshy fleshy, bottle-shaped or ovate-shaped rhizome running horizontally, with two leaves, terminally grown on pseudobulbs, papery and tender. Shixiantao polysaccharide has good antioxidant effect. Especially anti-superoxide anion effect. The polysaccharide content in Shixiantao is not only high, but also has the functions of nourishing yin, clearing lung, promoting dampness, and eliminating blood stasis. Benefits stomach, relieves cough, fights cancer and improves immunity. There are about 30 species in the genus Stenophyllum, whi...

Problems solved by technology

[0003] In order to solve the problems in the prior art that the seeds are extremely difficult to germinate under natural conditions, the ability of natural reproduction, the ability of propagation and diffusion is not strong, the difficulty of natural regeneration, and the slow propagation speed of ramets, the invention provides a kind of method that adopts pseudobulbs to induce shixiantao plants Regeneration and reproduction methods provide technical support for large-scale and industrial production
