摘要

栽培在本省低海拔地區之東方梨植株，於9月上旬以0.5%之氰胺噴施處理，可促進芽體整齊萌發，此新萌發之芽大部份可發育為短梢，而能在翌年1月前完成花芽分化，花芽形成率新興品種可達53.6%，豐水品種為41.3%，幸水品種為21.7%。於2月上旬再以2%氰胺噴施植株，可促花芽萌發，而開花結果，其萌芽率新興品種為74.3%、豐水為82.7%、幸水為39.8%。經過疏果、套袋等田間管理後，果實可在7月中旬至8月中旬收穫，果實品質與高接者相近。應用此種方式可在低海拔地區直接生產東方梨，能大幅降低目前以‘高接法’生產溫帶梨之成本。

Oriental pear was treated with 0.5% of hydrogen cyanamide during August and September to enhance bud emergence. One month after treatment, the buds underwent flower initiation when the leaves matured. In January of the following year, the flower formation was completed, the percentage of flower buds could reached at 18.6% to 53.6% in various variety. These flower buds appeared uniform emergence when trees were treated with 2% hydrogen cyanamide. This cultural practices designated as 'Twice Bud-forcing Culture' This method could solve the problem of bud dying and abnormal fruit shape to ensure the production of oriental pears at lowland areas in Taiwan. And, this cultural practice may replace the high labor and high cost 'Top-grafting method' in the near future.
