Mao bamboo seed embryo culture medium and seedling quick propagation method

Abstract

The invention relates to a bamboo blank culture medium, which uses MS as basic culture medium, with 3.1 or 4mg / L growth adjuster, nutriment at 3%, solidifier at 0.25%, and the pH value of medium is 5.7. The inventive production comprises that selecting seeds, absorbing water and activating, disinfecting, selecting blank, cultivating in tube, transplanting, and planting in field. The invention can improve the bamboo kind.

Description

technical field [0001] The invention relates to a tissue culture medium and a method for rapid propagation of seedlings, and is aimed at a culture medium for seed embryos of moso bamboo and a method for rapid propagation of seedlings using the embryos. Background technique [0002] Moso bamboo (Phyllosiachys heterocycla var pubescens) is a plant of the genus Bamboo in the subfamily Bambusae, also known as Phyllosiachys heterocycla var pubescens, and is a large-scale scattered bamboo. Moso bamboo is the economic bamboo species with the widest distribution, the largest area, the largest stock volume and the widest use in my country. But in every moso bamboo forest now, the seeds germinate into young bamboos at first, and then the bamboo shoots germinate gradually to form bamboo forests, or the female moso bamboos in different places are transplanted with bamboo whips, and then asexually propagated into forests. Every bamboo in the bamboo forest , is actually the branch that g...

Problems solved by technology

But in every moso bamboo forest now, the seeds germinate into young bamboos at first, and then the bamboo shoots germinate gradually to form bamboo forests, or the female moso bamboos in different places are transplanted with bamboo whips, and then asexually propagated into forests. Every bamboo in the bamboo forest , is actually the branch that grows from the underground stem of the mother bamboo year by year. If things go on like this, it will bring two problems: one is that it is difficult to collect excellent traits to achieve improved varieties, and the other is that for the same underground stem, the bamboo gardens are of the same age. , it is possible to bloom together and die as a whole, with disastrous consequences

[0004] Bamboos are divided into clustered bamboos and scattered bamboos according to the growth form of their plants. The tissue culture of clustered bamboos is easier than that of scattered bamboos, and the tissue culture of small scattered bamboos is less difficult than that of large scattered bamboos. The tissue culture of Moso bamboo has reached the level of difficulty. At the apex, there has been no report on the successful realization of the rapid propagation of Moso bamboo by tissue culture
