초록

The purpose of this study was to investigatethe effects of sowing time on the bio-active content ofmajor soybean cultivars in a southern region of SouthKorea. Experiments were carried out in Naju, JeonnamProvince (latitude 35° 04'N, longitude 126° 54'E) from 2008to 2010. The cultivars grown in summer included Saeolkongand Tawon-kong and those grown in autumn includedTaekwang-kong, Pungsannamul-kong, and Cheongja3,respectively. Sowing dates were May 15 and 30, June 15and 30, and July 15 of each year. Daidzein content wasincreased in all the test cultivars grown from later sowing,and the contents of genistein and total isoflavone wereincreased in all the test cultivars except for Cheongja3. Onthe other hand, glycitein content showed no significantchange in any of the test cultivars across the 5 sowingdates except for Tawon-kong. Cyanidin-3-glucoside (C3G)content was significantly increased in Tawon-kong andCheongja3, and delphinidin-3-glucoside (D3G) and totalanthocyanin contents were significantly increased in Tawonkong.
However, pelargonidin-3-glucoside (Pg3G) and petunidin-3-glucoside (Pt3G) contents showed no significant differencein plants sown across the 5 dates. Lutein content inCheongja3 was between 2.7 and 3.0 μg/g based on sowingdate and did not vary significantly, while chlorophyllcontent increased with later sowing and was significantlyhigher in the cultivars sown on June 30 and July 15. Crudefat content was higher in Taekwang-kong and Cheongja3when the cultivars were sown earlier; crude fat did notvary in the other test cultivars based on sowing date.
Palmitic acid composition was not affected by sowing datein most of the test cultivars. Stearic acid was increased inSaeol-kong, Tawon-kong, and Cheongja3 with later sowing.
Oleic acid and linoleic acid were significantly higher inSaeol-kong at an earlier sowing date. The composition oflinolenic acid showed significantly increased dates in mostof the test cultivars with later sowing. There were nosignificant differences in carbohydrate and crude proteincontent across 5 different sowing dates in most of the testcultivars. However, crude protein content was higher inSaeol-kong when sowing occurred earlier, and was higherin Tawon-kong at later sowing dates
