台灣的小果柑橘

Abstract

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，特別注重在菲律賓産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，酸橘是可作爲柑橘之砧木，而台灣産四季橘食用方式最多樣。比較以沸水沖泡台灣産四季橘及菲律寶産四季橘，兩種桔汁各有風味，尤以菲律寶産四季橘之口感極優具特殊芳香，可以推廣栽種。 The morphological characters of five small Citrus Fails of commerce in Taiwan and one introduced from the Philippine were comapred and a key of species was prepared for identification. The commercial usage were also surveyed. A special reference was mode to the comparison of Calamondin between plant introduced from the Philippine and which cultivated in Taiwan. In general, the size of leaves and the average numbers of seeds per frail of the introduced Calamondin are larger and numerous than that of cultivated one. Furthermore, when preparing for hot drink the uniqne flavor of the former stand out distinctively.
