≥80% of plants of both clones had a visible inflorescence when grown at constant 14, 17, 20, or 23 °C and at fluctuating day/night temperatures of 20/14 °C or 23/17 °C. None of the plants were reproductive within 20 weeks when grown at a constant 29 °C or at 29/17 °C or 29/23 °C day/night temperature regimens. The number of inflorescences per plant and the number of flower buds on the first inflorescence were greatest when the average daily temperature was 14 °C or 17 °C
