  1. 咖啡植物分類

  2. 分類地位 • Rubiaceae family 茜草科 • Coffea genus 咖啡屬 • Coffea arabica L. • Coffea canephora Pierre • Coffea liberica Bull ex Hiern • Coffea abeokutae Cramer • Coffea dewevrei de Wild and Durand • Coffea congensis Froh

  3. C. arabica • 目前全球栽培面積最廣,年代最久的物種 • 常綠多年生多幹型灌木,樹高8~10公尺 • 枝幹對生,細長柔軟,新生枝條屬半直立性,成熟枝條呈下垂或傘型 • 對生卵圓形葉片,短葉柄波浪狀葉緣,葉面光亮略帶皺摺 • 葉長約10-15公分,葉寬約4-6公分 • 花色白,帶有茉莉花香,花序叢生於對生葉葉柄的基部,屬於聚繖花序。具有2-3組花序,整圈花序約有8-15朵花 • 每朵花由短花梗連接於花序,花萼有五瓣萼片位於子房上方,筒狀花冠頂部多為五裂,具有五個獨立花絲與雄蕊,兩條細長柱頭凸出於雄蕊之上

  4. 咖啡果實 • 咖啡的果實屬於漿果(Cherry) • 咖啡果實的發育 • http://www.coffeeresearch.org/agriculture/beandevel.htm

  5. C. arabica咖啡品種 • http://www.coffeedna.net • C. arabica L. var. typica L. • C. arabica L. var. amarella Chev. • C. arabica L. var. maragogype Hort. • C. arabica L. var. bourbon (B. Rodr) Choussy • 著名的品種 Mundo Novo 豐產廣泛的適應力及耐性 • C. arabica L. var. laurine J. L. de Lanessan • C. arabica L. var. Mokka Cramer • C. arabica L. var. caturra KMC • 雜交品種 • Catuai 矮生品種 由Mundo Novo與Caturra Amarello • Timor 由C. arabica與C. canephora雜交

  6. C. canephora Pierre • 就是所謂的Robusta coffee • 僅次於C. arabica的栽培面積 • 主要產地為非洲,印尼,巴西北部與近年興起的越南 • 本物種為十九世紀末於非洲新發現的物種 • 屬於常綠灌木,多幹型,樹高可達8-10公尺 • 枝幹分枝長具有彈性 • 大型長橢圓形葉片20-35公分長8-15公分寬,葉片表面呈波浪狀,葉尖尖銳 • 花序腋生,1到3輪,每一輪有15-20朵花 • 花萼有5-7片萼片,每叢花序可有數十朵到多達百朵花
