9种冬青果实质地与颜色的差异比较

Comparison of Differences in Texture and Color of the Fruits of Nine Ilex Species

摘要: 以成熟期相近的9种冬青属植物果实为材料，对色度、花色苷含量、果实物理性质等10个指标进行了测定，对色度及花色苷含量等指标进行相关分析。结果表明：枸骨类冬青花色苷含量最高；冬青果实颜色指标中黄蓝色相值与饱和度的相关性最高为0.984，其次为亮度相值和红绿色，均达到显著相关；色相角和亮度及红绿色相值呈负相关。大叶冬青果实的硬度最高，质地指标中果皮硬度与果肉硬度关联性最高。果实颜色指标及物理特性的分析为冬青种质的分类、育种和开发利用提供参考依据。

Abstract: Nine species of Ilex plants with similar maturity stages were selected for the study, and their fruits were used as materials to determine 10 indicators, including color, flavonoid content, and physical properties of the fruits. Correlation analysis was conducted on indicators such as color and flavonoid content. The results showed that the holly species had the highest flavonoid content. Among the color indicators of the fruits, the correlation between the yellow-blue chromaticity value and satu-ration was the highest at 0.984, followed by the lightness value and red-green color, both of which achieved a significant correlation. The hue angle showed a negative correlation with lightness and red-green color. Ilex latifolia exhibited the highest fruit hardness, and the correlation between the fruit peel hardness and flesh hardness was the highest among the texture indicators. The analysis of fruit color indicators and physical properties provides a reference for the classification, breeding, and development of Ilex germplasm.
