Seaweed ultraviolet mutation breeding method and seaweed ultraviolet mutation breeding apparatus

Abstract

The invention provides a seaweed ultraviolet mutation breeding method and a seaweed ultraviolet mutation breeding apparatus. The seaweed ultraviolet mutation breeding method is used for solving a technical problem that seaweed breeding efficiency is low. The seaweed ultraviolet mutation breeding method comprises following steps: a seedling adhesion device is placed in a spore solution containing seaweed spores so as to realize adhering of seaweed spores onto the seedling adhesion device; the seedling adhesion device is placed below a ultraviolet lamp in the seaweed ultraviolet mutation breeding apparatus, and the ultraviolet lamp is controlled to emit ultraviolet light at a preset time to irradiate the seedling adhesion device until mutation of the spores of seaweed is realized; and survived mutated seaweed spores are cultured for selective breeding so as to obtain seaweed new species. According to the seaweed ultraviolet mutation breeding method, seaweed spores are irradiated with ultraviolet light so as to realize mutation of the spores, and excellent mutated seaweed stains are selected from adolescent plants cultured from the mutated seaweed spores for culturing and selective breeding, so that breeding efficiency is increased obviously.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to a seaweed ultraviolet mutation breeding method and a seaweed ultraviolet mutation breeding instrument for seaweed such as kelp. Background technique [0002] Kelp is not a native product of my country. It is cold-water seaweed. It was introduced to China in the late 1920s and was cultivated on a large scale in the northern region in the 1950s and 1960s. For decades after that, kelp has been the main species of seaweed farming in my country. The aquaculture area has expanded to the south to Fujian and northern Guangdong. At present, the three major production areas of Fujian, Shandong and Liaoning have been formed. Drive a large number of internationally influential enterprises in the middle and lower reaches, including alginate and food processing. [0003] Kelp culture mainly includes two stages: kelp breeding and kelp breeding. Kelp is a typical generation-alternating plant. The...
