Method for carrying out test tube grafting and rejuvenization on paulownia fortunei select tree

Abstract

The invention provides a method for carrying out test tube grafting and rejuvenization on paulownia fortunei select tree, comprising the following steps: grafting and rejuvenation of select trees; tissue culture and test tube grafting and rejuvenization; explant sterilization; primary culture; test tube grafting and rejuvenization; secondary enrichment culture; induced rootedness; and seedling adaptation and transplantation. In the invention, the select trees suffering from serious ripening are grafted and rejuvenated; then tissue culture and test tube grafting and rejuvenization are carried out on the select tree to overcome the defects that the root segment of the paulownia fortunei select tree is difficult and the germination rate of buffing roots is low so as to effectively realize rejuvenization of the paulownia fortunei select tree, shorten rejuvenization cycle of the paulownia fortunei select tree, and powerfully promote breeding process of the paulownia fortunei. In the invention, the pronounced problem that the paulownia fortunei select tree suffers from serious ripening and low capacity in vegetative propagation can be solved, rejuvenization success rate and rejuvenization efficiency of the paulownia fortunei select tree can be improved and scientific research costs can be reduced.

Description

Technical field: [0001] The invention relates to a method for juvenile paulownia excellent trees, in particular to a method for in vitro grafting and young paulownia white flower excellent trees, which is suitable for young paulownia white flower excellent tree materials with serious maturation effect, and improves the growth rate of paulownia white flower Asexual reproduction ability of Youshu. Background technique: [0002] Paulownia is one of the most important fast-growing high-quality timber tree species and ecological protection tree species in my country. It has always played an irreplaceable role in the construction of commercial forests and ecological environment protection in China. my country is also the country with the richest germplasm resources and the widest distribution range of paulownia in the world. In the mainland alone, there are nine species with two varieties and many variant types. Among them, Paulownia albiflora grows fast, has a wide range of adap...
