PRODUCTION OF HIGH CHILLING ASIAN PEAR IN TAIWAN'S LOWLAND

Authors:	H. Lin, C. Lee, C. Lin
Abstract: "Shinseiki" and "Hengshan" are two major cultivated varieties of Asian pear (Pyrus serotina Rehd) in Taiwan. "Shinseiki" has a longer chilling requirement than "Hengshan" and is planted only at high elevations. Grafting a chilled scion, with floral bud, of "Shinseiki" onto a "Hengshan" water shoot grown in the lowland, permits the harvest of fruits of both cultivars from one tree within one year. The following factors are critical for success: Scion and stock must be compatible. Grafting must be timed to achieve synchronous flowering, thus avoiding competition between the scion and the stock.
