‘검정콩1호Õ와 ‘진주1호Õ를 공시하여 검정콩 종피의 안토시아닌 색소들에 대한 파종시기(4월 15일, 5월 15일, 6월 15일)와 생육단계(R6, R7, R8)별 함량과 변화를 분석하여 기능성 검정콩의 품종육성 및 이용에 대한 기초 자료를 얻고자 실험한 결과는 다음과 같다. 1. Delphinidin-3-glucoside, cyanidin-3-glucoside, petunidin-3-glucoside 및 total anthocyanin의 함량은 모두 6월 15일 파종에서 높았다. 2. 생육단계별 Delphinidin-3-glucoside, cyanidin-3-glucoside, petunidin-3-glucoside 및 total anthocyanin의 함량은 R6에서 R8으로 갈수록 증가하였다. 3. 안토시아닌의 Hunter's value인 L, a, b값 중 명도인 L값은 6월 15일 파종에서 가장 낮았으며, 적색도인 a값은 6월 15일 파종에서 가장 높았고, 황색도인 b값은 파종기간에 차이가 없었다. 4. 생육단계별로는 명도인 L값은 R6에서 R8으로 갈수록 낮았으며, 적색도인 a값과 황색도인 b값은 R6에서 R8으로 갈수록 높았다. 5. 안토시아닌 색소와 Hunter's value의 값들과의 상관관계는 delphinidin-3-glucoside, cyanidin-3-glucoside, petunidin-3-glu-coside, total anthocyanin, a, b값은 모두 상호간에 고도의 정(+)의 상관관계를 나타냈으며, L값만이 D3G, C3G, Pt3G, TA, a, b값과 고도의 부()의 상관관계를 나타내었다.
This experiment was conducted to investigate the content and color difference of anthocyanin with black soybean seedcoats as influenced by different planting dates and growth stages. Two varieties, Geomjeongkong #1 and Jinju #1 were tested. Planting date was on April 15, May 15, and June 15 and growth stage was measured three stages at R6 (full seed), R7 (physiological maturity), and R8 (harvest maturity). The content of delphinidin-3-glucoside (D3G), cyanidin-3-glucoside (C3G), petunidin-3-glucoside (Pt3G), and total anthocyanin (TA) were all higher on June 15 as planting date. The accumulation patterns of D3G, C3G, Pt3G, and TA from R6 (full seed) to R8 (harvest maturity) had all increased gradually from R6 to R8 as growth stage. In the L, a, and b of anthocyanin pigments according to planting dates, L as lightness was lowest on June 15 and a as redness was highest on June 15 but b as yellowness was not different among planting dates. In the L, a, and b of anthocyanin pigments according to growth stages, L had decreased from R6 to R8 whereas a and b had increased from R6 to R8. D3G, C3G, Pt3G, TA, a, and b showed reciprocally highly significant positive correlation. L only showed highly significant negative correlation with D3G, C3G, Pt3G, TA, a, and b.
