摘要：

为探究湖北省主栽核桃品种在不同采收期表观性状和营养组分的变化,以主栽品种秭林一号和清香核桃为研究对象,于4个不同采收期采收核桃,测定核桃的表观性状和营养组分,结合相关性分析和主成分分析法对4个不同采收期核桃的品质进行综合评价。结果表明,在采收期内,秭林一号和清香核桃的横径、纵径、出仁率和青果开裂率呈现不断升高的趋势。在营养组分方面,脂肪含量呈上升趋势,含水率、蛋白质含量和钙含量呈下降趋势,总氨基酸和锌含量则呈现先减少后增加的变化。相关性分析表明,各营养组分间的相关性较强。主成分分析显示,2个主成分代表了9个指标95.356%的变量信息,能全面反映核桃营养品质的整体变化,核桃品质的综合得分随着采收期的推迟明显升高,且在采收期Ⅳ达到最高。此外,适时推迟采收期能显著提高核桃的营养品质,湖北省主栽核桃秭林一号和清香的最佳采收期为8月27日左右。

Abstract:

To explore the changes in apparent traits and nutritional composition of the main cultivated walnut varieties planted in Hubei Province at different harvest periods. The main cultivated walnut varieties Zilin No.1 and Qingxiang were used as objects, the appearance traits and nutritional composition of walnuts at different harvest periods were measured. A complete evaluation of the quality of walnuts from four distinct harvest periods was conducted by correlation analysis and principal component analysis. The results showed that during the harvest period, the transverse and longitudinal diameters, kernel yield rate, and cracking rate of green fruit of Zilin No.1 and Qingxiang walnuts demonstrated a continuous upward trend. In terms of nutrient composition, the fat content showed an upward trend, while the moisture content, protein content, and calcium content showed a downward trend. The total amino acid content and zinc content, however, exhibited a pattern of initial decrease followed by an increase. Correlation analysis indicated that there were generally considerable relationships between the different nutritional components. Principal component analysis showed that 2 principal components represented 95.356% of the variable information of the 9 indicators, which could comprehensively reflect the overall changes in the nutritional quality of walnuts. Comprehensive score for characterizing the quality of walnuts increased significantly with delayed harvesting and reached its highest level at harvest period IV. Furthermore, appropriately delaying the harvest period can significantly improve the nutritional quality of walnuts. The optimal harvest period for the main cultivated walnut varieties Zilin No. 1 and Qingxiang in Hubei Province, is around August 27th.

Key words: walnut, harvest period, apparent traits, nutritional composition, principal component analysis
