摘要： 本研究包括兩部份。其一為研究新引進柑橘品種之果實發育、品質與貯藏。其二為研發實用而低成本的處理與貯藏方法以增進台灣主要品種柑桔之品質並延長其供銷期間。第二部分本年度進行四項試驗。1. 追蹤使用不同濃度2,4-D保鮮後在貯藏期間之殘留量變化。2. 比較以「益收」(Ethrel) 催色與乙烯催色椪柑之效果及實用性評估。3. 測定椪柑與柳橙樹冠內外採收之果實耐貯藏性及貯藏障礙差異。4. 南部生產之柳橙運往比較冷涼之北部，貯藏在普通通風貯藏庫、窯洞貯藏庫及冷藏庫比較其效果，並評估前者可替代後者之程度。普通貯藏及窯洞貯藏成本低而有節能減碳之特性；研究其實用化是主要目標。This research project has two distinct parts. Part one studies the growth and development, quality and proper storage methods for the fruit of a newly introduced citrus variety. Part two targets at developing practical low-input technologies for handling and storage of major citrus fruits to improve the quality while extending the market period of the fruits. There are 4 experiments in part two. 1. Monitoring 2,4-D residues in ‘Ponkan’ mandarins and ‘Liucheng’ oranges after the chemical being applied at various concentrations and the fruits being stored for various periods. 2. Degreening ‘Ponkan’ with Ethrel in comparsion with ethylene. 3. Differences in the storability and storage disorders of ‘Ponkan’ and ‘Liucheng’ fruits harvested from inside vs. outside of tree canopies. 4. Storing southern grown ‘Liucheng’ in common ventilated storage, cave storage and cold storage located in the cooler northern area. The major goal is to test the practicality of low imput and low energy-demand common storage and cave storage for Taiwan citrus.
