The present study was conducted to control Botrytis growth of cut roses during transport by applying hot water dipping. Water temperatures ranging from 40 – 70℃ and dipping time from 10 – 90 s were evaluated in vitro and in vivo. Hot water dipping at 50℃ inhibited mycelial growth depending on dipping time. Water temperature over 60℃ completely inhibited the pathogen growth even at exposure of 10 s while water below 40℃ did not have any effect. However, temperature over 60℃ rapidly damaged the tissue of rose petals. Dipping time below 40 s at 55℃ showed no significant difference on electrolyte leakage compared to control. In vivo, dipping flower heads in hot water reduced the severity of Botrytis rot. Dipping for 20 – 90 s at a temperature of 50℃ was more effective than at higher or lower temperatures. Heat treatment increased respiration rate and decreased slightly solution uptake, transpiration, fresh weight of flowers but dipping below 50℃ for 20 s did not affect vase life.

When kiwifruit root system infected with nematodes was treated by hot water dipping treatment, the maximum temperature for this treatment was suggested as 50℃. The lowest killing temperature of internal root-knot in the root tissue was 48℃. Consequently, root-knot nematodes could be killed without damaging root tissues by the hot water dipping treatment at 48℃ for 10 minutes. This could be useful for organic production and distribution of kiwifruit seedlings by avoiding the synthetic nematicides which are not easily decomposed in soil once applied.

풋고추의 저장성 향상을 위한 저장전 열처리 조건을 구명하기 위하여 풋고추를 50, 55, 60, 의 온수에 각각 10초 침지하여 열처리를 하였다 에서 10초 열처리한 경우는 열처리 직후 과육표면에 가열장해 현상이 나타났다. 온수에서 침지한 풋고추를 1의 저장고에서 4주 동안 저장하면서 관능적 품질, 화학적 품질과 미생물학적 품질을 측정하였다. 표면 색도 중 L 값은 저장 중 조금씩 감소하는 경향을 보였으며, a 값과 b 값은 저장 3주까지는 거의
