Sargassum fusiform line differentiation and classification method

Abstract

A method provided by the present invention is applicable to the aspects such as sargassum fusiform germplasm resource analysis, artificially cultured sargassum fusiform group line classification, elite seed and pedigree seed near-source genetic relationship analysis and manual seedling screening by using sexual reproduction of sargassum fusiform. The method mainly comprises the operating steps of sargassum fusiform history feature and sargassum fusiform mature sporophyte morphological feature main component morphological measurement, sargassum fusiform mature sporophyte morphological feature correlation mathematical model analysis, sargassum fusiform mature sporophyte morphological feature main component mathematical model analysis, sargassum fusiform mature sporophyte morphological feature main component cluster mathematical model analysis, and sargassum fusiform mature sporophyte line differentiation and classification determination and the like. The present invention may provide a scientific differentiation and classification method for the aspects such as sargassum fusiform germplasm resource investigation, sargassum fusiform mature sporophyte group diversity analysis, sargassum basic scientific research and experimental sample screening, sargassum fusiform introduced seed morphological feature stability analysis, manual elite seed differentiation and screening by using sexual reproduction of sargassum fusiform and asexual reproduction excellent plant rhizoid storage.

Description

technical field [0001] The invention relates to a method for identifying and classifying Hijiki strains, which is suitable for the investigation of Hijiki germplasm resources, the diversity analysis of Hijiki mature sporophyte populations, and the basic scientific research of Hijiki (reproductive physiology, ecological biochemistry, Quality analysis, genetic diversity, etc.) sample screening, morphological stability analysis of hijiki introduction or cross breeding, artificial use of hijiki for sexual propagation of fine varieties identification and screening, and artificial use of hijiki for asexual propagation of excellent plants rhizome preservation, etc. scientific research and agricultural production. Background technique [0002] Hijiki is a low-tidal zone, large-scale, edible and medicinal brown algae unique to the coastal waters of the Pacific Northwest. Due to the influence of geographical distribution, the morphology of mature sporophytes of different latitudes of...

AI Technical Summary

Problems solved by technology

Due to the influence of geographical distribution, the morphology of mature sporophytes of different latitudes of Hijiki populations is significantly different. Northeast Asian countries have carried out scientific research on Hijiki since the late 1930s. Technological breakthroughs have been made in this area, but due to the extremely insignificant morphological differences between the young sporophyte and the sporophyte stage in the life cycle of Hijiki, and the insignificant morphological difference in the mature sporophyte stage, scientific researchers and researchers engaged in Hijiki Sargassum seedling breeding technicians have been in a non-scientific way of empirically identifying or naming sargassum based on geographical group characteristics in terms of uniformity analysis of mature algae, strain classification, strain variability analysis, and sexual reproduction vegetable selection. In the classification stage, this phenomenon is not uncommon in the existing domestic and foreign scientific research literature reports on Hijiki
