Abstract

|
The study was conducted to evaluate postharvest physiological properties of muskmelon fruits from soil and hydroponic culture. Ripening response was examined during storage at different temperatures. Production of C₂H₄ and CO₂ was higher in fruit harvested from hydroponic culture than soil culture and significantly higher at room temperature than at 5℃ or 13℃ for one day storage. Pulp firmness was harder in fruits harvested from soil culture than hydroponic culture and was much harder in the outer pulp than the inner pulp. It held longer for 15 days at low temperature (5℃ and 13℃) compared to room temperature. Soluble solid and sugar contents were higher in soil culture than hydroponic culture. Glucose and fructose content were not changed regardless of storage conditions, but sucrose content was decreased as storage period extended. Ethanol and acetaldehyde were detected a little quantity at harvest, but during storage at higher temperature, the contents were significantly increased in the inner pulp. Sensory evaluation of taste and texture showed the highest value in storage for 20 days at 5℃, 10 days at 13℃ and 5 days at room temperature. The results suggested that optimum taste and texture was developed after a certain period of ripening from harvest and that quality was better in soil-cultured fruit than hydroponic-cultured fruit.
