摘要:

研究不同产地对纽荷尔脐橙果实物理特性和化学组分的影响。实验样品采自中国17 个产地代表性果园。结果表明:不同产区纽荷尔脐橙果实质量、总可溶性固形物(total soluble solids,TSS)含量、可滴定酸度(titratable acidity,TA)、糖组分、有机酸、矿质元素和氨基酸含量等物理特性和化学成分均显著不同。相关性分析结果显示,不同产区纽荷尔脐橙的品质特性、有机成分组分和含量、矿质元素含量以及氨基酸组分与年平均气温、年降雨量和日照时数的相关性不同。其中,TSS含量与年平均气温、年降雨量和日照时数都极显著相关;TA和VC含量均与年平均温度和日照时数有关;果肉中的精氨酸和天冬氨酸含量同日照时数和年降雨量成显著负相关,而果皮中的赖氨酸含量与相对湿度成极显著正相关。

Abstract:

The aim of this study was to investigate the effect of geographical origin on physical characteristics and chemical
compositions of Newhall navel oranges from different areas. Samples from 17 growing areas in China indicated significantly
differences in physical characteristics and chemical compositions, including fruit weight, total soluble solid (TSS) content,
titratable acidity (TA), sugar components, organic acids, mineral elements and amino acids. Correlation analysis revealed
obvious variations among geographical origins allowing successful differentiation of Newhall navel orange according to their
quality characteristics and organic components. TSS content very significantly correlated with mean annual temperature,
annual rainfall and sunshine hour. TA and vitamin C were closely associated with mean annual temperature and sunshine hour.
Additionally, Mineral contents and amino acid composition as useful chemical parameters also revealed significant differences
among different locations. Significantly negative correlation of Arg and Asp contents with sunshine hour as well as annual
rainfall was found for pulp but not peel; Lys in peel showed highly significant correlation with relative humidity.
