Abstract
Eucharis plants, which had been grown at 30°C, were exposed to 15°C for 10 days and then transferred to 20°C or 30°C. Most of the plants transferred to 300C flowered, whereas some plants transferred to 20°C did not.
Plants flowered sporadically in the control bed where the soil temperature was not regulated.
The flowering percentage was increased by heating the soil immediately after the soil-chilling.
The number of flowering stems obtained per square meter per year was 7.3 in the control bed, 10.3 in the chilled bed, and 19.3 in the chilled and heated bed.
