Selection of Soybean Accessions with Seed Storability Test Under Accelerated Aging Conditions
조현,Noy Noy,송종태,이정동 한국육종학회 2023 Plant Breeding and Biotechnology Vol.11 No.4
Soybean [Glycine max (L.) Merrill] seed has poor storability under high temperature and high humidity. It losesviability in a relatively short time. Seed aging of stored soybeans leads to poor germination and a decrease in yield. The acceleratedaging vigor test, which provides useful information for determining seed storability as well as field emergence potential, is a rapid agingexperiment and could be used to determine soybean seed quality. This study was conducted to determine the seed viability of Koreansoybean cultivars and soybean lines with altered fatty acid compositions under accelerated aging conditions. Results demonstrated thatSonghagkong, a Korean soybean cultivar, was the most stable at 3, 4, and 5 days of accelerated aging conditions. Furthermore, twosoybean lines with high stearic acid content exhibited >70.0% reduction rate, whereas three soybean lines with high oleic acid contentexhibited 7.4%-11.8% reduction rates. Soybean lines with mid-oleic acid and elevated linolenic acid contents exhibited variousreduction rates depending on genotypes. Therefore, these soybean lines can be used as breeding material for developing a new soybeancultivar with strong seed vigor and better storability under unfavorable conditions. Therefore, a genetic study on this soybean cultivaris warranted.

The purpose of this study was to investigate the influence social support on negative affectivity and dance continuance intention in art high school. 233 patients was used to analyze the data of the art high school dance majors as subjects. For research purposes we used a structured questionnaire study. For data analysis was mad by AMOS confirmatory factor analysis structural equation model. The results were as followings. First, was to reduce the negative tendencies of the art high school dance majors in social support. Teacher support and organizational support had a negative(-) impact on the negative affectivity. Second, negative affectivity had a negative(-) impact on the dance continuance intention. In summary, it can be seen that the factors that reduce the negative affectivity of the social support of the arts high school dance majors. Therefore, you need to increase support for the social support of the students and the teacher to lead the school organization. In addition, we discuss the empirical field, taking into account the nature of the dance, based on the results of theory and social support.
