Embodiment 1

[0035] A method for tissue culture and rapid propagation of Eucalyptus grandis 1212 variety, which uses an excellent individual plant of Eucalyptus grandis excellent provenance, cuts it down to promote germination, collects bud strips to induce aseptic buds, and subcultures the aseptic buds Cultivation, rooting culture and light substrate seedling cultivation to obtain regenerated plants;

[0036] The tissue culture rapid propagation method of the Eucalyptus grandis 1212 variety specifically comprises the steps:

[0037] (1) Establishment of explants: Select excellent individual plants from the excellent provenance stand of Eucalyptus grandis introduced from Australia (that is, the excellent provenance of Eucalyptus grandis introduced from Australia, through cultivation test, measurement and analysis, after measuring diameter at breast height, Tree height, volume, annual growth, wood properties and dry shape indicators, after a comprehensive comparison, select the best tree fr...

Abstract

The invention relates to the technical field of eucalyptus cultivation, in particular to a tissue culture and rapid propagation method of a 1212 variety of Eucalyptus cloeziana F. Muell. According tothe tissue culture and rapid propagation method, excellent individual plants of Eucalyptus cloeziana F. Muell. excellent provenance are adopted, cut down and subjected to germination promoting, budlings are collected for inducing sterile buds, and regenerated plants are obtained through subculture, rooting culture and light-substrate seedlings of the sterile buds. The tissue culture and rapid propagation method of the 1212 variety of Eucalyptus cloeziana F. Muell. is low in operation difficulty, low in production cost, stable in growth of an aseptic propagation system, high in proliferation coefficient of subculture seedlings, good in repeatability and high in rooting rate of rooting seedlings, the produced tissue cultured seedlings are high in survival rate, stable in genetic traits and tidy in forest form, the seedlings can maintain the excellent genetic characteristics of excellent trees, large-area planting is suitable, and large-scale production and promotion are easy.

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 1212 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...
