Abstract

The aim of this study was to evaluate the change of phenolic compounds after bordeaux mixture treatment on Cheorwon onion. Onion is a perennial plant belonging to the lily family. It is native to Persia of Southwest Asia. It is cultivated much in the temperate regions of the world. Onion is a good name for the 'Okchong' to drop blood cholesterol and cardiovascular blood flow to increase the prevention of adult diseases. Cheorwon area is inland, but it has high continental climate due to its high altitude. After the treatment with bordeaux mixture, the weight, width and plant height of the onion were affected to some extent. In the phenolic compounds, caffeic acid, ferulic acid, rutin, and kaempferol except benzoic acid, p-coumaric acid and quercetin were similar to or less than the control. Therefore, it was concluded that the treatment with bordeaux mixture had some effect on onion growth and phenolic compound contents.

본 연구는 철원양파에 친환경제제로 사용되는 석회보르도액을 농도별(1.5:0.5, 2:2, 4:4식)로 처리하여 생육특성과 페놀화합물 함량의 변이를 알아보기 위해 수행되었다. 그 결과 석회보르도액 4:4식은 양파의 구 무게, 구경, 초장에 어느 정도 영향을 미친 것으로 판단된다. 또한 석회보르도액 처리 후 페놀화합물 benzoic acid(1.5:0.5, 2:2, 4:4식), p-coumaric acid(1.5:0.5), quercetin(1.5:0.5, 2:2)의 함량이 무처리구에 비해 다소 증가하였다. 따라서 석회보르도액 처리는 양파의 생육과 페놀화합물 성분 함량 변화에 어느 정도 영향을 준다고 판단된다. 또한 본 연구가 농가에 실질적으로 적용되기 위해서는 좀 더 넓은 면적에서 시험한 후 적용할 필요성이 있을 것으로 판단된다.
