内容記述（抄録等）
Forcing of cut and pot flowers in tree peony (Paeonia suffruticosa) timed for New Year Days and retarding for autumn flowering were tested.
Saturated ethanol vapor, 1% ethylene and 100% nitrogen promoted sprouting of flower buds and extension of leaves, and accelerated harvest date of flowers when they were treated to the plants in which bud dormnacy was partially broken by low temperature treatment. Rate of blindness was low in ethylene treatment, but still higher than in control.
For retarded flowering, plants stored at 4℃ and -2℃ for months flowered normally in June and in Nov, respectively.
