Rapid Breeding Method of Cultivated Seedlings of Pig Bloodwood

Abstract

The invention provides a rapid breeding method of Euryodendron excelsum cultivation seedlings. The method comprises the steps of explant selection and disinfection, aseptic seedling culture, clustered bud induction, rooting culture, seedling strengthening culture and seedbed culture. Compared with traditional seedling growing methods of Euryodendron excelsum, the method provided by the invention has the advantages of small amount of needed Euryodendron excelsum seeds, realization of short-time mass propagation, keeping of excellent hereditary features of Euryodendron excelsum, good quality of seedlings, low malformed seedling rate, high survival rate of the seedlings reaching 90%, high survival rate of cultivated seedlings reaching 80%, good growth vigor of transplanted nursery stocks, no runt seedlings, effective solving of the problems of increasing reduction of wild resources and difficult natural population updating of Euryodendron excelsum, and provision of technical support for effective protection of the rare and endangered plant Euryodendron excelsum.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a rapid breeding method for cultivated seedlings of S. hematoma. 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 rema...

AI Technical Summary

Problems solved by technology

[0005] Still another object of the present invention is to provide a rapid breeding method for Hematoma japonica seedlings, which uses the seeds of Hematoma japonica for tissue culture to obtain seedlings of Hematoma japonica, and transplants the seedlings into the seedbed to continue cultivating to obtain cultivated seedlings of Hematoma japonica. 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 cultivated seedlings is as high as 80%. After transplanting, the seedlings grow well without "little old man". The emergence of the phenomenon of seedlings solves the problem of dwindling wild resources and the difficulty of natural regeneration of the population, which is conducive to the effective protection of this rare and endangered plant.
