초록
옥수수의 항산화 활성에 대한 N-P-K의 시비의 효과를 알아보고자, 찰옥 2호와 수원 19호 두 품종을 대상으로 시비량에 따른 옥수수의 항산화 활성과 tocopherols, 페놀화합물, carotenoids의 함량을 분석하였다. 시비 수준은 N, P, K 각각에 대한 표준 시비량과 이의 1/2 및 2배 그리고 무비이었다. 찰옥2호의 항산화 활성은 19.0~22.2%로, 수원19호보다 높았다. 찰옥 2호의 항산화 활성은 표준 시비구에서 가장 높았으나, 처리간의 유의성은 없었고, 수원19호의 항산화활성과 항산화 성분 함량은 질소 2배 시용구에서 높았다. Tocopherols, 페놀화합물, carotenoids의 함량은 찰옥2호의 경우 각각 30.0~38.1, 104.7~118.8,
Antioxidant activity and related components including tocopherols, phenolic compounds and carotenoids in the corn(Zea mays L.) kernels were measured to understand effects of fertilizer application. Hybrids used were Chalok 2, a waxy corn, and Suwon 19, a dent corn. The standard fertilizer level of N-P-K was 14.5-3-6 for Chalok 2 and 17.4-3-6.9 for Suwon 19. The treatments of the fertilizer levels were the standard level, half and two fold amounts of N, P, and K, and no fertilizer. The antioxidant activity was determined by measuring electron donating ability. The antioxidant activity of Chalok 2 was higher than Suwon 19. The antioxidant activity was the highest at the standard fertilizer treatment for Chalok 2, but was statistically not significant. The antioxidant activity and the related compounds content in Suwon 19, however, were the highest in the two fold nitrogen treatment, and the differences were significant. The contents of tocopherols, phenolic compounds and carotenoids were 30.0~38.1, 104.7~118.8,
