The purpose of this study was to investigate the effect of sea buckthorn (Hippophae rhamnoides) fruit extract (SBFE) on the quality attributes of beer. In this study, four style beers such as Golden Ale (GA), Amber Ale (AA), Golden Lager (GL) and Pale Ale (PA) were prepared. As the quality attributes of beer, the total acid, alcohol, reducing sugar, and total sugar of sea buckthorn beer (SBB) were analyzed. All beer`s total acid had a tendency to decrease and alcohol level increased except for AA when the SBFE was added. As SBFE was added, GA`s reducing sugar and total sugar level increased but those of AA, GL and PA decreased. In the sensory evaluation of SBB, total acceptance, color, aroma, total flavor, acidulous, sweet, bitter, and soda acceptance were evaluated. There was no significant difference in the total flavor among SBBs but in evaluation of color and aroma, SBB without SBFE had higher score than SBB with SBFE. The total acceptance of SBBs decreased as the following order; PA, GL, PA3%-S, GL3%-S, AA, AA3%-S.

코이어 자루재배시 일중 급액마감시각을 달리함으로써 최적 생장을 유지하면서도 용수이용효율(WUE)와 비료이용효율(FUE)를 높이기 위해 실험을 실시하였다. 급액마감시각에 따라 일몰 1시간 전부터 4시간 전까지 4단계로 나누어 처리한 결과, 하루 동안의 배지 내 수분함량은 마감시각의 영향을 크게 받는 것으로 나타났는데, 급액마감시각이 빠를수록 일일 수분함량 변화폭이 컸다. 그러나 일일급액횟수는 급액마감시각의 영향이 크지 않았는데 이는 급액제어 시스템으로 배액전극 제어법을 사용한 것과 코이어 배지의 이화학적 특성 때문으로 판단되었다. 최종 생육은 통계적 유의차를 보이지 않았다. 상품과량은 일몰 2시간 전 처리에서 가장 많았고, 4시간 전 처리에서 가장 적었다. 급액마감 시각 처리별 128일 동안의 급액량을 조사한 결과, WUE와 FUE는 일몰마감 4시간 전 처리에서 가장 낮았고, 2시간 전 처리에서 가장 높았다. 식물생육, 수확량 및 WUE와 FUE 등의 면에서 일몰 1시간 전 처리와 4시간 전 처리는 경제적인 면에서 바람직하지 않았고, 2시간 전에 급액을 마감하는 것이 가장 경제성이 좋을 것으로 사료된다. This research was performed to determine the appropriate daily last irrigation time to enhance the plant growth and the water and fertilizer use efficiencies in coir bag culture for tomato plant. The time to finish the daily irrigation was set by 1, 2, 3 and 4 hours before the sunset. The water content in the substrate was greatly affected by the last irrigation time. The earlier the last time, the greater the daily fluctuation of water contents in the substrate. The daily irrigation times were not affected by using irrigation management system controlled by drainage electrodes or the physiochemical properties of coir. The growth characteristics were not significantly different among the treatments. The highest marketable yields were obtained in the treatment finishing two hours before sunset, and the lowest yields were obtained in the the treatment finishing 4 hours before sunset. Based on the result from surveying quantity of irrigated water for 128 days of the experiment period, the water and fertilizer use efficiencies were lowest in the treatment finishing 4 hours before sunset, and the highest in the treatment finishing 2 hours before sunset. In terms of plant growth, yields, water and fertilizer use efficiencies, 2 hours before sunset treatment was determined as the most economical and desirable irrigation schedule.
