Tissue Culture and Rapid Breeding Method of Pig Bloodwood

Abstract

The invention provides a tissue culture and rapid propagation method of euryodendron excelsum. The method comprises the following steps: selecting and disinfecting explants, inducing clustered buds, proliferating clustered buds, rooting and culturing, culturing strong seedlings and culturing a seedling bed. Compared with the conventional seedling-raising method of euryodendron excelsum, the method does not adopt euryodendron excels seeds; the new sprout seedlings of the euryodendron excelsum are adopted; few plant raw materials are needed; the euryodendron excelsum is subjected to short-time and mass propagation; the heritable variation of the variety is low; the young seedlings is high in quality; the survival rate of the young seedlings reaches up to 90%; the survival rate of transplanted seedlings reaches up to 80%; after transplanting, the seedlings are excellent in growth vigor; the phenomenon of small seedling is avoided; the problems that the euryodendron excelsum wild resources are increasingly reduced and natural reproduction of the population is difficult can be effectively solved; the technical support is provided for effective protection of euryodendron excelsum serving as a rare and threatened plant.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a rapid propagation method of blood tree tissue culture. Background technique [0002] Euryodendron excelsum H.T.Chang belongs to the family Theaceae (Theaceae) Euryodendron excelsum is a perennial woody plant. It is a rare and endangered plant with a unique monotype in my country and has been listed as a national second-class protected plant. The systematology position of the pig blood wood is special, and it is an important material for studying the phylogeny and morphological evolution of the camellia family. At the same time, its trunk is straight, the heartwood is beautiful, and the wood is extremely hard. It is an excellent building material and furniture material, and has a certain economic value. . At present, the pig blood tree is only distributed in the area of ​​Bajia Town, Yangchun County, Guangdong Province, and only one population remains. The...

Problems solved by technology

[0005] Still another object of the present invention is to provide a rapid breeding method for blood tree tissue culture, which uses tissue culture of the young shoots of blood wood in the same year to obtain seedlings of blood wood, and transplants the seedlings into the seedbed to continue culturing to obtain blood wood Transplanting seedlings, this breeding method can effectively improve the breeding coefficient of S. hemataceae, retain the excellent genetic characteristics of S. hemataceae, the survival rate of seedlings is as high as 90%, and the survival rate of transplanted seedlings is as high as 80%. After transplanting, the seedlings grow well , there is no phenomenon of "little old man seedlings", which solves the problem of the dwindling wild resources of the blood tree and the difficulty of natural regeneration of the population, and is conducive to the effective protection of the rare and endangered plant of the blood tree
