Outline of Final Research Achievements

To improve the supply of mango fruits, it is important to understand the production condition, the distribution system and physiological characteristics for fresh fruits. In this study, we evaluated the water management in mango orchards of‘Nam Dok Mai' in Thailand. Moreover, we investigated the actual distribution condition by ship and by air and the effects of the postharvest environment of fresh mango fruit on its physiological characteristics during distribution from Thailand to Japan. We used four quality indicators, namely respiration rate, peel color, hardness score, total sugar content, to quantify fresh fruit quality after harvest. Every indicator decreased with storage period and high temperature (15~35 degree Celsius). Moreover, accumulated respiration had high correlation with peel color, hardness score and sugar contents, respectively. Fruit quality changes during distribution were used to evaluate the potential market loss.
