Abstract

A Cultivation method to minimize the damage caused by high temperatures was studied by investigating the effects of groundwater cooling treatment on the growth, yield, and quality of strawberries. In the groundwater cooling treatment, the daily average temperature of the rhizosphere was reduced from $26.9^{\circ}C$ to $24.9^{\circ}C$. The root length increased by 0.3-9.2 cm, depending on the cultivar and growth period. The leaf number, leaf area, leaf length, leaf diameter, and plant height also increased, especially in the cultivars 'Seolhyang' and 'Maehyang', resulting in higher fresh and dry weights. The number of fruit per plant increased from 7.7 to 12.5 in 'Seolhyang', and the fruit weight increased by 0.3 g in 'Seolhyang' and 1.3 g in 'Maehyang'. The fruit hardness increased, but no significant difference in fruit coloration was observed. The sugar content of the fruit was improved by $0.2-0.3^{\circ}Brix$. Therefore, groundwater cooling of the rhizosphere was effective in improving the growth and productivity of strawberries under abnormally high temperature conditions and can be considered a cost-efficient cooling system.
