Abstract

The invention relates to the technical field of eucalyptus cultivation, in particular to a tissue culture and rapid propagation method of a eucalyptus cloeziana 1203 variety. The method comprises thefollowing steps of adopting an excellent single plant of an excellent seed source of eucalyptus cloeziana, cutting down and promoting germination of the excellent single plant, collecting bud sticks for inducing sterile buds, and performing subculture, rooting culture and container seedling culture on the sterile buds to obtain a regenerated plant. The tissue culture and rapid propagation method of the eucalyptus cloeziana 1203 variety is low in operation difficulty and production cost; a sterile propagation system is stable in growth, subcultured seedlings are high in multiplication coefficient and good in repeatability, rooted seedlings are high in rooting rate, produced tissue culture seedlings are high in survival rate, stable in inheritable character and tidy in forest form, and nursery stocks can keep excellent inheritance characteristics of superior trees and are difficult to mutate; and the method is easy for large-scale production and popularization.

Description

technical field [0001] The invention relates to the technical field of eucalyptus cultivation, in particular to a method for tissue culture and rapid propagation of Eucalyptus grandis 1203 variety. Background technique [0002] Eucalyptus cloeziana (scientific name: Eucalyptus cloeziana F. Muell.) is a large tree species of Eucalyptus genus in Myrtaceae. It is naturally distributed in central and northern Queensland, Australia. Up to 1 ~ 2m. This tree species grows rapidly, the trunk is straight and round, and the natural pruning is good. The wood is yellowish-brown, straight in texture, uniform in structure, heavy, strong, high in hardness, and durable. It is a good sawn timber, known as "redwood" in eucalyptus, and can be used for high-end furniture, solid wood floors, mechanical components, Buildings, mine pillars, pit logs, etc. Eucalyptus species with large inflorescences are resistant to drought and barrenness, have strong resistance to diseases and insect pests, an...
