【摘要】 以 拉宾斯 、 斯坦勒 等7个生产上主栽的欧洲甜樱桃品种为试验材料,研究了不同品种采收后果实可溶性蛋白质、维生素C Vc 、可溶性总糖和总酸等主要内含物含量的差异.进一步分析了各主要内含物含量与果实发育期、果实大小以及相互之间的相关性.结果表明:甜樱桃品种果实可溶性蛋白质和总糖含量与果实发育期均呈显著正相关,说明发育期短的早熟品种果实可溶性蛋白质和糖含量显著低于果实发育期长的中、晚熟品种 P<0.05 ;甜樱桃品质标准在 中上 级以上,果实的可溶性蛋白质含量范围在1052.0～1119.3mg·100g-1FW;品质在 中上 标准以上的果实维生素C的含量范围在9.89～18.01mg·100g-1FW;7个甜樱桃品种之间果实总酸度差异显著 P<0.05 ;甜樱桃果实的糖酸比值与果实发育期和可溶性糖含量均呈显著正相关,甜樱桃果实的糖酸比值能确切地反映果实风味及品质的优劣,可以作为一项指标,甜樱桃品质在 中上 标准以上的果实糖酸比范围在31.37～40.54;早、中、晚熟品种之间相比较,甜樱桃早熟品种的果实大小显著低于中、晚熟品种 P<0.05 .更多还原

【Abstract】 Differences in the soluble protein, Vc, total soluble sugar and acidity contents of post-harvest fruit among seven main production cultivars of Prunus avium Linn.,Lapins, Stella, Sunburst, Van, Germersdorfer, Hedelfinger and Burlat, were investigated.The bivariate correlations between main fruit inclusions and fruit developmental periods and fruit size or between the factors of the main fruit inclusion were analysed. The result showed that the correlation between fruit developmental phases and fruit soluble protein content and total soluble sugar content was positively significant. This meant that soluble protein and total sugar contents in the fruit of early ripening sweet cherry variety with a shorter fruit developmental phase were significantly （P<0.05） lower than the of middle and late ripening sweet cherry varieties with a longer fruit developmental periods. The fruit soluble protein concentrations in the fruit of sweet cherry varieties with a moderately high fruit quality classification standard ranged from 1052.0 to 1119.3 mg·100g^-1FW. The Vc concentrations in the fruit of sweet cherry varieties with a moderately highfruit quality classification standard ranged from 9.89 to 18.01 mg·100g^-1FW. The difference of total acidity contents in fruit between any two sweet cherry varieties was significant （P<0.05）. The correlation between fruit sugar-acid ratio and fruit developmental period and total soluble sugar content was positively significant. The sugar-acid ratio could be used as an index accurately to evaluate fruit flavor and Quality. The sugar-acid ratios in the fruit of sweet cherry varieties with a moderately high fruit quality classification standard ranged from 31.37 to 40.54. Comparatively speaking, the fruit size of early ripen sweet cherry varieties was significantly smaller than those of middle and late ripen sweet cherry varieties （P<0.05）.更多还原
