Abstract: Variations of the external form of Tse-pear (Pyrus bretschneideri cv. Tse-li) occurred after flowernipping. It became conical in shape in comparing with the natural rounded spindle-shaped pear without flower-nipping. The wound periderm formed rather rapidly on the floral tube after flower-nipping. Four days after flower-nipping, the initiation of phellogen became visible. Seven days later, the cell division of phellogen increased and the cork layer formed near the surface. After 15 days, the closed-layer on the surface and the hypertrophic cell layers mostly collapsed, cork cells increased and they subsequently formed the protective layer. The effects of flower-nipping on the yield of pear depended upon the degrees of treatment. In heavy treatment, the yield decreased about 15% from the harvest.
