본 연구의 목적은 온도와 토양수분에 따른 마늘의 생육, 생리장해 및 수량에 미치는 영향을 구명하고자 실시 하였다. 실험은 온도가 6℃ 차이가 나는 온실에서 수행 되었는데, 정식부터 수확까지 외기(A)보다 3℃(A+3℃), 6℃(A+6℃) 고온조건, 토양수분은 적습(OI) 대비 수확기 무렵의 다습(EI) 처리를 하였다. 그 결과, 마늘 생육특성은 온도와 토양수분 조건(0.34m3/m3)에 따라 고도의 유의성을 보여 고온일수록 그리고 적습 처리구일수록 컸다. 초장은 외기보다 A+6℃-OI 처리구에서 47.4cm로 가장 컸으며, 엽장과 엽폭 역시 외기보다 A+6℃-OI 처리구가 각각 16.1cm, 2.4cm로 가장 컸다. 마늘재배 기간 중 외기보다 3℃, 6℃ 고온조건이 되면 스펀지마늘 발생율이 높아져 A+6℃-OI 처리구는 12.9% 발생하였고, A-EI 처리구에서는 전혀 발생하지 않았으며, 인편무게와 1쪽당 무게는 A+6℃ 고온구에서 크게 감소하여 수량이 외기 대비 A+6℃ 처리구는 평균 51%, A+3℃ 처리구는 평균 22% 감소하였다. 따라서, 마늘재배시 외기보다 6℃ 고온조건과 다습조건이 되면 상품수량 감소하고, 생리장해 발생이 많아지는 것으로 나타났다.

The objective of this study was to determine the effects of combination of air temperature and soil water contents on growth, physiological disorder rate, and yield of garlic. This experiments has been carried out in the typical plastic house (one side open and other side installed ventilation fans) which was maintained gradient air temperature (maximum different value of air temperature : 6℃). The excessive irrigation (EI) set at 0.34 m3/m3 soil moisture contents. The significant differences found in the growth parameters of garlics as affected by air temperature and soil moisture conditions. The plant height of garlic with combination of ambient (A)+6℃ and optimal irrigation (OI; set at 0.22 m3/m3 soil moisture contents) treatments represented 47.4 cm/plant, which was the highest among all the tested treatments. The leaf length and width showed the greatest, which were 16.1 and 2.4 cm/plant, respectively, in A+6℃OI. The physiological disorder ratio was higher as 12.9% at A+6℃-OI and was not occurred at ambient temperature with EI compared with OI treatment. The bulb and clove weight were dramatically decreased at A+6℃ temperature treatment. The yields were decreased by 51% in OI at A+6℃ and A+3℃ temperature treatment. Those results indicated that yields were decreased and ratio of physiological disorders was increased by high temperature treatments.
