| Abstract:
The objective of our study was to determine the effect of high day-temperature in plastic greenhouse before harvest on the quality and storability of cucumber in summer. The shelf life of high-temperature treated and control cucumber fruit was 16 and 14 days at 10°C storage, respectively. However that of both treatments at 20°C storage was 12 days. The fresh weight loss of fruit in high-temperature treatment (average day temp.; 32±1°C) and control (average day temp.; 27±1°C) was not found to be significantly different. Chilling injury was observed only on control fruit after 12 days at 10°C storage. Ion leakage from mesocarp disks was the lowest in high-temperature treated fruit at 10°C storage. Firmness and vitamin C contents of cucumber were found to be higher in high-temperature treatment than control during 10°C storage. The cultural high-temperature treatment in summer improved the storability of cucumber at 10°C. | |
