결구상추의 수확후 물올림을 위한 처리를 위해서 육묘 시에 부직포 포트를 이용하여, 저장 시 선도 유지 효과를 검토하였다. 결구상추 육묘 시 프러그 트레이와 부직포 포트를 사용한 결과 수확 시 생육에 차이가 보이지 않았다. 따라서 부직포 포트를 이용한 육묘 방법이 포장 및 저장 방법 개선을 위한 물올림 처리에 이용할 수 있는 것으로 판단되었다. 수확후 결구상추의 경정(줄기)을 부직포로 감아 물올림을 실시한 후 포장하여 저장하면, 무포장은 생체중이 감소하는데 비해 물올림 처리는 저장 28일에 1.7%까지 증가하였다. 그 외 엽록소(SPAD), 색도(hue angle)에서 물올림 처리의 측정치가 무처리 보다 높은 결과를 보였다. 따라서 결구상추의 선도유지를 위한 효과적인 저장방법으로 물올림 처리가 효과적인 것으로 보이며, 물올림을 위한 포장의 편이를 위하여 육묘 방법의 개량 가능성을 확인하였다. 앞으로 다른 원예작물에서도 저장 후 선도를 개선하기 위해서는 재배에서부터 수확후 품질에 중점을 둔 추후의 연구가 더 필요할 것으로 사료된다.

The research was aimed to improve pre-harvest methods to maintain marketability in postharvest coniferous lettuce. Non-woven pots or plug plates were used to generate seedlings. No difference was found in growth characteristics of lettuce grown in non-woven pots vs plug plates. Since, seedling method with non-woven pots was convenient, lettuce harvested from non-woven pots used for water dipping treatment. The quality parameters, such as fresh weight loss, SPAD value, and appearance of lettuce were investigated after harvest. The lettuce with dipping treatment inside the plastic box container showed lower weight loss, higher SPAD value and better appearance compared to those exposed to the control (non-packaging) during the storage at 2℃. The treated plant showed higher SPAD and hue angle values 21.9 and 113.8°, respectively, compared to that of 18.8 and 108.3°, in non-treated plants. Therefore, it seems that the water dipping treatment is effective for storage method to maintain freshness of the lettuce. We showed the non-woven pot growing as a convenient seedling method for packaging treatment. Further studies will be continued to improve freshness postharvest of other horticultural crops.
