摘要

摘要: 分别对河南省27个果园的中华猕猴桃（Actinidia chinensis Planch.）品种‘金桃’果实的5项采收生理指标及果实软熟时的8项品质性状进行测定，采用主成分分析法对果实软熟时的品质指标进行综合评分，并对果实的采收生理指标、果实软熟品质指标及综合分值间进行相关性分析。结果显示，采收时的生理指标（干物质、色度角、硬度和可溶性固形物）均与果实软熟品质综合分值间呈极显著相关，其中干物质相关系数最高，为0.437。干物质与体现果实软熟品质的关键指标（可溶性固形物、总糖和糖酸比）均呈极显著性相关。研究结果表明‘金桃’果实采收时，干物质含量是果实软熟时品质的重要评价指标，而可溶性固形物和色度角是评判采收期的辅助指标。

Abstract: Five harvest indices of ‘Jintao’ kiwifruit (Actinidia chinensis Planch.) from 27 orchards in Henan Province were measured, including average fruit weight, hue angle, firmness, soluble solids content (SSC), and dry matter. Eight fruit quality parameters were measured at the mature stage, including average fruit weight, hue angle, firmness, SSC, total sugar (TS), titratable acids (TA), ratio of TS/TA, and proportion of ripening fruit (PRF). A comprehensive score of fruit quality for each orchard was obtained through principal component analysis based on the eight fruit quality parameters. The correlations between harvest indices and comprehensive score and other fruit quality parameters were analyzed. Results showed that all harvest indices were significantly associated with the comprehensive score, with the highest correlation coefficient found for dry matter (r=0.437). Dry matter was also significantly correlated with three other fruit quality traits, including SSC, total sugar and TS/TA, with correlation coefficients of 0.578, 0.324 and 0.279, respectively. Hue angle was significantly correlated with the proportion of mature fruits. Dry matter was the main index for evaluating fruit quality in the ‘Jintao’, followed by SSC and hue angle.
