Heng Shan pear (Pyrus serotina Rehd), an Oriental Sand Pear strain, was used in the investigation of bud dormancy and regulation of time of production. It grows at low altitude in Taiwan and has a very short chilling requirement. The bud of Heng Shan pear, in general, breaks in February, then the fruit mature in August. In this experiment, the whole tree was defoliated by spraying with P.C.P. (80% Sodium salt of pentachlorophenol) in the early October. approximately about 20 days after the treatment, flowers were forced, then fruits developed in the winter and matured in the spring. In order to increase the percentage of bud was completed and vegetative maturity arrived.
The sbscisic acid content in the fruit bud of Heng Shan pear increased during late August and rised dramatically in autumn, but the rate of fruit bud break was all above 60% during autumn and winter in the lathhouse.
