배추김치의 저장 온도와 저장 기간별 total GSLs 함량을 분석하기 위하여 2007년 6~7월, 8~9월, 10~11월, 12~4월 및 5월(2008년) 수확하여 제조한 배추김치를 anion-exchange column을 통과시키고 아세톤 침전법을 사용하여 제조한 crude myrosinase로 반응시켜 함량 변화를 측정하였다. 수분 함량의 경우 8~9월 배추김치가 다른 기간에 제조된 배추김치에 비해 높게 나타났으며 pH의 경우 저장 3일,

A gene flow has been tested from transgenic herbicide-resistant Chinese cabbage to major crops in Cruciferae. Hybridizations were made between transgenic Basta-resistant Chinese cabbage and non-transgenic Chinese cabbage, B. napus, B. juncea and Brassicoraphanus(B. campestris × Raphanus sativus, 2n=4x=38) with honey-bee mediated fertilization. Progeny populations were selected by Basta herbicide. The F1 hybrids with pat gene were again self-pollinated or cross-pollinated with nontransgenic Chinese cabbage and rape naturally or artificially. Pod setting ratio were compared as a tentative parameter for potential gene flow. Key agronomic characters were compared among the F1 hybrid populations obtained. In the days to flowering after cold treatment, the F1 hybrids of Brassicoraphanus x B. campestris and B. napus x B. campestris(GM) were the shortest (75 days), and the GM Chinese cabbage and the F1 hybrid of B. juncea x B. campestris(GM) were 87 and 93 days, respectively. In the stem length, the F1 hybrid of Brassicoraphanus x B. campestris was the longest(175 cm), and followed by the F1 hybrid of B. napus x B. campestris(GM), the F1 hybrid of B. juncea x B. campestris(GM) in order. The naturally occurring pod setting ratios were fluctuated seriously among individual and segregation lines. Natural pod setting of the transgenic Chinese cabbage was 10 to 19 %. The F1 hybrid of B. napus x B. campestris(GM) showed the ratio of 4-11%. However, the F1 hybrids of B. juncea x B. campestris and Brassicoraphanus x B. campestris(GM) did not produced seeds. The F1 hybrids with pat gene were hybridized with nontransgenic Chinese cabbage and rape by artificial bud pollination to test potential gene flow. All cross combinations except Brassicoraphanus produced seeds and the pod setting ratios ranged from 35 to 100 percentages. Thus, the potentials of the gene flow from Chinese cabbage with pat gene to the order specise in the same gene interspecies or intergeneric species and from the F1 hybrids with pat gene to nontransgenic Chinese cabbage and rape were detected. Herbicide resistant test to the acquired seeds by natural and artificial pollinations including honey-bee mediated fertilization using the same materials is going on.

김치는 절임 발효 식품으로서 염장이 품질에 영향을 미치는 중요한 요인이다. 이러한 영향에 대해 주재료인 배추의 품종 및 재배 방법의 차이를 구명하고자하였다. 배추의 재배방법(노지, 하우스재배) 및 품종(쌈노랭이, 매력, 춘황, 춘광, 고령지 여름, 옥황씨알)에 따른 수확전 요인(생육 특성)과 수확후에 나타나는 절임특성을 조사하고자 구중, 결구지수(크기), 엽수, 엽두께, 삼투몰 농도, 염함량, 탈염률, 경도를 측정하였다. 수확후 생육면에서는 시설
