摘　　要：从主要经济性状和一般营养成分两个方面评价了产于云南的三叶悬钩子、栽秧泡、灰毛果莓、红泡刺藤、茅莓和红毛悬钩子等6种悬钩子的果实品质,结果表明:灰毛果莓在果实重量、果实大小、总糖含量、糖酸比等指标上均居首位,开发价值最高;栽秧泡和红泡刺藤的维生素C含量和可溶性固形物含量大大超过其他4种的相应含量,其余指标居中,开发价值高;茅莓的果实含水量和出汁率最高,果实重量和大小均居第二,其他指标多居中等,也有较高的开发价值;红毛悬钩子的各项指标处于中下水平,开发价值低;三叶悬钩子在果实重量、果实大小、总糖含量、糖酸比、维生素C含量等多项指标上均居末席,但总酸含量却最高,开发价值最低。在6种悬钩子中,有5种悬钩子果实的营养成分均属首次报道;比较了滇产茅莓和资料报道的外省茅莓的维生素C含量,发现产于云南的茅莓果实的维生素C含量要远远高于其他省所产的相应含量。The fruit qualities of Rubus delavayi Franch. , R. ellipticus var. obcordatus （Franch.） Focke, R. foliolosus D. Don, R. niveus Thunb. , R. parvifolius L. and R. pinfaensis Levl. et Vant. distributed in Yunnan Province were evaluated from main economic characters and general nutrition of fruits. The results showed as follows,R, foliolosus D. Don occupied the first places of fruit weight, fruit size, total sugar content and sugar-acid ratio and had the highest ex- ploitation value. R. ellipticus var. obcordatus （Franch.） Focke and R. niveus Thunb. were much higher than other four species in contents of Vc and soluble solid and had high exploitation value. R. paruifolius L. occupied the first places of water content and rate of juice formation and the second places of fruit weight and fruit size, and also had high exploitalion value. R. pinfaensis Levi. et Vant. occupied later places in all indexes and had low exploitation value. R. delavayi Franch. occupied the last places of fruit weight, fruit size, total sugar content, sugar-acid ratio and Vc content and also occupied the first place of total acid content and had the lowest exploitation value. The fruit nutrition of 5 Rubus species were reported first and the Vc content of R. parvifolius L. distributed in Yunnan Province were much higher than those distributed in other provinces.
