Abstract
為改善碰柑隔年結果現象，在嘉義竹崎12年生及臺中東勢10年生之果園進行藥劑(NAA)疏果與隔年結果強度之研究，並評估其合理產量。疏果試驗分別以0、200、300、400及500ppm NAA溶液於5月上旬，約盛花後50日，果徑約0.5至1 cm之生理落果中期施用。採完全逢機之試驗設計，每重覆1株，5重覆，計25株。To adjust the alternate bearing of 'Ponkan' mandarin (Citrus reticulata Blanco) experiments were conducted in two commercial orchards located in Chia-yi and Tong-shih (planted in 1979 and 1983 respectively). Five single-tree replicates were sprayed with NAA at rate 0, 200, 300, 400 and 500 ppm in early May (50 days after full bloom), and fruit drop, yield and fruit quality were investigated.
