Chrysanthemum mother plants (various cultivars) which had been exposed to low temperatures in the previous winter were grown at low (2 degrees C), moderate (15 degrees ), natural or high (> 20 degrees ) temperatures during the summer. Rooted cuttings from these plants were planted in the autumn, pinched 2 weeks later and grown under long days for several weeks before being transferred to short days for flower initiation. The minimum night temperature was 10 degrees from 1 November onwards.
