EFFECT OF FRUIT QUALITY AND YIELD ON BED TEMPERATURE IN HIGH BED SYSTEM

The purpose of this study was to identify the effect of temperature treatment on fruit quality and yield in high bed cultivation of strawberry. ‘Akihime’ cultivar was used as the plant material in this study and all plants were grown in a greenhouse under controlled high-bed temperature of 12°C, 16°C, 20°C and control (no heating). The result shows that the average weight was heavier in temperature treatments than in the control treatment, but there is no major difference among the temperature treatments.
The total and marketable yield was highest in the 16°C treatment, followed by 12°C, 20°C and the control treatment.
The quality of fruit was best in the control treatment, followed by 12°C, 16°C, and 20°C, showing that sugar and acidity content were higher in a low temperature.
Although the quality of fruit shows no significant difference between the 12°C and 16°C treatment, the sugar content of 12°C and 16°C is 10.7°Bx and 10.4°Bx, respectively, showing that quality was better in a lower temperature.
In temperature treatments on high bed system, the 12°C and 16°C treatments showed better growth, high quality and high yield.
Even though there were no significant differences between two treatments in yield, marketable yield, and fruit quality, considering the cost, 12°C temperature treatment in high bed was preferred.
