Abstract
콩의 파종시기 및 생육온도를 달리하였을 때 생육반응, 수량성 및 isoflavone 함량과 지방산 조성에 미치는 영향을 검토하여 밭작물의 안정생산을 위한 재배기술개발에 활용하고자 수행된 연구결과를 요약하면 다음과 같다. 1. 5월파종구는 6월파종구에 비해 콩 식물체의 생육이 왕성하고 식물체의 수분함량이 개화후 약 40일까지 비교적 높은 상태가 유지되지만, 6월파종구는 개화 후 등숙이 빠르게 진행되면서 식물체의 수분함량이 개화후 30일부터 급격히 감소되었다. 2. 6월 파종구는 5월 파종구에 비해 100립중이 상대적으로 감소하였고, 생육온도가 높으면 100립중이 증대되었으나 control + $5^{\circ}C$에서는 오히려 감소되어 파종시기 및 생육온도별 등숙 반응이 달랐다. 3. Isoflavone 함량은 5월파종구의 평균이 $1201.8{\mu}g/g$이었으나 6월파종구는 $1479.8{\mu}g/g$으로 5월파종구 대비 약 $278{\mu}g/g$ 함량이 높았다. 생육온도에 따라서는 5월파종구 Mc + $3^{\circ}C$ 및 Mc + $4^{\circ}C$ 처리구는 isoflavone 함량이 증가되었으나, Mc + $5^{\circ}C$의 isoflavone 함량은 오히려 낮았고, 6월파종구는 생육온도가 높을수록 isoflavone 함량이 감소하여 파종시기별 온도처리 효과가 달랐다. 4. 생육온도가 높을수록 oleic acid의 조성이 증가되고 linoleic 및 linolenic acid가 감소되었으나 palmitic 및 stearic acid의 조성도 생육온도가 높아질수록 증가되는 경향이었다. 5. 주경절수는 isoflavone 함량 및 불포화지방산 조성에 모두 관여하는 변수로 나타났는데, 주경절수와 isoflavone 함량과의 상관분석 결과 부의 상관관계(r = -0.661)가 있었고, 불포화지방산과는 정의 상관관계(r = 0.775)를 보여 주경절수가 증가되면 isoflavone 함량이 낮아지고 불포화지방산의 조성비율의 증가에 관여하는 형질로 판단되었다. Soybean, C.V. Daewonkong, was planted on 25 May and 25 June in 2011, and four temperature gradient, control (ambient temperature in field plot), control + $3^{\circ}C$, control + $4^{\circ}C$, and control + $5^{\circ}C$, were artificially created by controlling the green house system. The obtained results indicated that vegetative growth of soybean plant was beneficially facilitated by planting on May (PM) than planting on June (PJ). The 100-seed weight was significantly higher in PM, and positively affected by increasing temperature, whereas the weight was reduced in control + $5^{\circ}C$ plot. Isoflavone content and fatty acid composition were analyzed to determine the effects of plating date and growth temperature. Isoflavone content was higher in PJ plot ($1479.8{\mu}g/g$) than in PM plot ($1201.8{\mu}g/g$), however, the influence of growth temperature varied with planting date. The composition of oleic acid was positively affected by increasing temperature, whereas the proportions of linoleic and linolenic acid were reduced. The numbers of node was considered as a major variable in the regression equations estimated using forward stepwise regression analysis for isoflavone content and unsaturated fatty acid under different environmental conditions.
