樹齡及果實大小對椪柑品質的影響

Effects of Ages of Trees and Sizes of Fruits on Qualities of Ponkan Mandarin

本研究以台中縣新社鄉之不同樹齡所產不同周徑的椪柑為試驗材料，探討其物理化學與官能品質在不同採收期的變化與差異。結果顯示：1.椪柑之大小主要影響早期採收椪柑之酸度、檸檬酸含量、糖酸比及官能品質，包括酸味與整體喜好性等。2.樹齡主要影響早期採收之椪柑的酸度、檸檬酸含量及糖酸比，但對其官能品質無顯著影響。

Using different sizes of Ponkan mandarin from different ages of trees produced at Hsingsheh in Taichung county as the experimental materials, their physicochemical and sensory attributes were analyzed to investigate the quality changes and differences during harvesting periods. The results are summarized as follows: 1. Sizes of Ponkan mandarin affect the acidity, citric acid content, °Brix/acidity and sensory qualities of sourness and overall preference during early harvesting periods. 2. Ages of trees affect the acidity, citric acid content and °Brix/acidity during early harvesting periods, but they do not affect sensory qualities of Ponkan mandarin significantly.
