유전자형과 재배환경에 따른 검정콩 안토시아닌 함량변이

Abstract

Variation of anthocyanin contents were analyzedby different growing environments, three locations over threeyears with 3 black colored soybeans. Anthocyanin contentswere different according to growing location, genotypes andplanting time, so it can be concluded that anthocyanin contentwas effected by environmental and genetic variation. Plantingdate seemed to have a much greater influence on anthocyanincontent than cultivar and location. Among different plantingdates, anthocyanin contents increased in the seeds plantedon June 15 rather than did May 30 and May 15. Comparedwith 3 cultivars and 3 locations, Ilpumgeomjungkong andYeonchun had higher contents such as 11.58 mg/ and 9.85mg/g, respectively. The correlations between color indexand anthocyanin content were analyzed by Hunter’value. L(lightness) and b (yellowness) values were correlated negativelywith D3G, C3G, Pt3G and total anthocyanin content whilea (redness) value was correlated positively. The correlationsbetween meteorological factors and anthocyanin content wereanalyzed. Anthocyanin content was correlated negatively withmean temperature and accumulated temperature whereas meandaily temperature difference showed positive correlation. Wecould conclude that the area in which mean temperaturewas low and daily temperature difference was high is goodfor attempts to improve black soybean seed quality by theincrease of anthocyanin contents
