Tulip cv. 'Cassini' were forced under computer control system. The temperature was controlled using overhead unit heater, and it showed small difference, within 1.6℃ at average from point to point in the system. Consequently, the numher of days from planting to flowering changed from 51 to 66.
In spite of these differences in growth duration, flowers were almost equal in quality.
For the production of desirable flowers in quality, it seemed that, 58 or 60 days of growth period during which the sum of temperature reached to about 700℃ were necessary.
