摘要

爲達到外銷品質之要求，中部地區的椪柑應在11月中旬左右採收，此時椪柑已完全成熟，可於室溫儲放二星期，對果重減失率及儲放後品質之變化影響甚微，不過此地區因氣候乾燥又缺乏灌溉，故椪柑之果汁含量遠較其他産區者爲低。
由鄧肯氏多種變域顯著性之測定結果，顯示不同採收期，採收地區對椪柑果實大小、內容品質均有差異性之存在。此可說明目前中部地區所産之椪柑品質頗不整齊，且糖酸比率不高，平均爲10.6:0.62，故風味淡泊、汁液少、種子數多，爲了爭取外銷之市場，似應積極加強選種、栽培及管理，以提高品質。

In order to meet the requirement of the foreign markets, the quality and size of the ponkan (Citrue reticulata Blanco) fruit harvested in the central part of Taiwan were measured by this investigation through three sampling areas and seven picking maturities. Result shows that better quality and shelf-life from the samples picked at the time on the middle November as after stored at room temperature for two weeks would be obtained as indicated by this report,
Due to the dry season and the short of irrigation system, ponkan fruit growing in this district especially at Sian-kaung country of Taichung Prefecture was less juice content as compared with other producing areas. From Duncan's multiple range test. it shows that interior quality and the fruit size were significant difference between those three sampling areas and each picking maturities The average data of the quality are revealed in poor taste from its low ratio of soluble solids to acidity of the juice with 10.6:0.62 or 17.5:1, and more seeds and some semidried segments were presented in those fruits growing in such central part of Taiwan. In order to improve those quality factors, mush research work such as selection of better strains, set up more irrigation systems and better orchard managments etc. must be urgently established.
