台灣的小果柑橘

The Small Citrus Fruits in Taiwan

本研究比較長實金柑、圓實金柑、寧波金柑、酸橘、台灣產四季橘及菲律賓產四季橘等六種小果柑橘的形態特徵，製作檢索表，特別注重在菲律賓產四季橘和台灣產四季橘之差異，並調查小果柑橘的應用情形。結果顯示：菲律賓產四季橘比台灣產四季橘之葉片較大且平均種子數較多，但其範圍均有部份重疊。小果柑橘的檢索表製作，先以子房室數特徵區別金柑屬與柑橘屬，金柑屬內再選用果實形狀鑑定出長實金柑、圓實金柑和寧波金柑。柑橘屬內則以葉緣特微及葉面色澤區別酸橘與四季橘。探討小果柑橘的應用情形，酸橘是可作為柑橘之砧木，而台灣產四季橘食用方式最多樣。比較以沸水沖泡台灣產四季橘及菲律寶產四季橘，兩種桔汁各有風味，尤以菲律寶產四季橘之口感極優具特殊芳香，可以推廣栽種。
