温室中7个樱桃品种果实内在品质比较

以7个樱桃品种为试验材料，在设施栽培的条件下研究了不同品种采收后果实可溶性糖、可滴定酸、糖酸比、维生素C （Vc）、蛋白质等主要营养物质含量的差异，进一步分析了各主要物质变化间的相关性.结果表明：美早（AM）的可溶性糖的质量分数最高；明珠（MZ），AM和黑珍珠（BLA）的可溶性固形物的质量分数显著高于其他品种；AM和BLA品种的维生素C的质量比显著高于其他品种；早大果（EBF）和红灯（RED）果实的可滴定酸的质量分数显著高于其他品种，BLA酸度最低；BLA果实的糖酸比最高.AM，MZ和RED的可溶性蛋白质的质量浓度显著高于其他品种.隶属函数综合分析显示樱桃果实内在品质的优劣依次为AM，BLA，MZ，RED，矮化萨米特（mSUM），萨米特（SUM），EBF.SPSS相关性分析显示各品种樱桃果实中的V_C的质量比与可溶性糖的质量分数，蛋白质的质量浓度与可溶性固形物的质量分数的变化呈显著的正相关性.综合比较分析7个樱桃品种的内在品质后认为：AM品种为北方设施栽培7个品种中内在品质最好的品种，是温室栽培的较好樱桃品种.

Comparative Analysis of Fruit Internal Quality of Seven Cherry Varieties in a Solar Greenhouse

Soluble sugar, titratable acid, sugar/acid ratio, vitamin C (Vc), protein and other major nutrients of 7 cherry varieties (AM, BLA, SUM, mSUM, SUM, MZ and EBF) grown in a greenhouse were studied after fruit harvest. The results showed that soluble sugar of AM was the highest; soluble solids of MZ, AM and BLA were significantly higher than those of other cultivars; vitamin C of AM and BLA was significantly higher than that of other cultivars; titratable acid of EBF and RED was significantly higher than that of other varieties; BLA had the lowest acidity in all varieties and sugar/acid ratio of BLA was the highest. Soluble protein of AM, MZ and RED was significantly higher than that of other varieties. Based on the results of membership function comprehensive analysis, the internal quality of the cherry varieties studied was in the order of AM,BLA,MZ,RED,mSUM,SUM,EBF. SPSS analysis showed that VC content in the cherry fruit was in a significant positive correlation with total sugar, protein and soluble solids. In summary, of the 7 cheery varieties studied AM has the best internal quality of fruit and is recommended for protected cultivation in North China.
