Abstract
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.
