荆州地区6个柑橘品种成熟期果实品质的比较

以南丰蜜桔(橘类)、国庆1号(柑类)、日南一号(柑类)、朋娜(橙类)、玉环柚(柚类)、琯溪蜜柚(柚类)等6个柑橘品种为试材,对各柑橘品种果实的主要品质特性,如果形、单果质量、果形指数、可食率、Vc含量、可溶性固形物含量、可滴定酸含量、可溶性糖含量、糖酸比和固酸比等指标进行测定和比较分析。结果表明:玉环柚及琯溪蜜柚的果实均较大,单株产量高,果实硬度也较大,而且其糖含量、可溶性固形物含量和糖酸比均较其他柑橘品种合适,且Vc含量亦较高;其次则是南丰蜜橘,其具有相对较高的可溶性固形物和Vc含量,同时具有最高的可食率;其他的几个柑橘品种果实的品质相关指标测定结果均存在或多或少的缺憾。

Comparative of the Fruit Quality of Six Varieties of Citrus in the Jinzhou Area

In this experiment,the six citrus cultivars of Nanfeng orange（Citrus）,Guoqing No. 1（Orange）,Rinan No.1（Citrus）,bonanza（Orange）,Yuhuan pomelo（Citrus grandis） and Guanxi pomelo（Citrus grandis） were selected as experiment materials. The main quality characteristics of the varieties of Citrus fruit such as the shape of fruit,edible rate,the weight of single fruit,the index of the shape of fruit,Vc content,soluble solids content,titratable acid content,soluble sugar content,the ratio of sugar to acid and the ratio of solid to acid were menstruated. The results showed that Yuhuan grapefruit and Guanxi pomelo fruit are larger than other varieties of citrus fruit. And in the same time,their weight of single fruit and fruit hardness are larger as well. Besides that,the sugar content,the soluble solids content and the ratio of sugar to acid are all higher than other varieties of citrus fruits,and the content of Vc is higher,too. Secondly,Nanfeng orange has relatively higher soluble solids and vitamin C,also has highest edible rate. The determination results of the other several varieties of citrus fruit for the related quality indexes are more or less having some regrets.
