| 摘 要： | 【目的】探究不同颜色育果袋对‘瑞雪’苹果(Malus×domestica Ruixue)果实品质的影响，为生产高品质‘瑞雪’苹果提供理论依据及技术支持。【方法】以5年生‘瑞雪’苹果为试材，于花后70 d分别采用红、橙、黄、绿、蓝、靛、紫单层木浆纸育果袋进行套袋处理，以单层白色育果袋为对照，于花后190 d统一采收。采用光谱仪测定不同颜色果袋内透射光光谱，测定果皮叶绿素、果实可溶性固形物、总类黄酮含量、果实糖组分及香气物质含量等品质指标，通过相关性分析法探索光质与果实品质之间的相互关系，探讨不同光质对果实品质的影响。【结果】不同颜色育果袋内光质组成主要与果袋颜色有关，其中，与白色果袋对照相比，紫光、红光分别在对应颜色的果袋中透过率均为最高，分别为对照的1.15、1.13倍。不同颜色果袋处理后，果皮的L*和b*值均高于对照白色果袋，而a*值、果点指数、着色指数均低于对照。与其他彩色果袋相比，紫色果袋处理后的果皮叶绿素(0.0548 mg·g-1)、果实总酚(1.325 mg·g-1...

| Abstract: | 【Objective】The aim of this study was to explore the effects of different color of fruit bags on the fruit quality of Ruixue apple (Malus × domestica Ruixue), so as to provide the theoretical guidance and technical support for the production of high-quality Ruixue apples. 【Method】The experimental materials were five-year-old trees of Ruixue using M26 as rootstock, bagged with red, orange, yellow, green, blue, indigo and purple single-layer fruit bags at 70 days after full bloom, with white bags as control. The fruits were harvested at 190 days after full bloom. The transmitted light spectrum of bags was measured by spectrometer. The indicators of fruit quality were determined, such as peel chlorophyll, ascorbic acid, soluble sugar and aroma compounds contents. To explore the effects of different light qualities on fruit quality, the relationship between light and fruit quality was analyzed by correlation analysis. 【Result】The difference in the color of the fruit bags changed the composition of the light quality and had a positive correlations between light quality and fruit bags. Compared with white bag control, the transmittances of purple in purple bag were the highest, which were 1.15 times than that in white bag; meanwhile, the transmittances of red in red bag were the highest (1.13 times). The external quality of fruits was significantly improved after the treatment of different color fruit bags. Among the indicators, the L* and b* values of the peel were higher than white bag control, while the a* value, fruit point index and coloration index were lower. Compared with other color fruit bags, some indicators of purple fruit bags were significantly improved (P < 0.05), such as chlorophyll (0.0548 mg·g-1), total phenolic (1.325 mg·g-1), and total flavonoid content of fruits (1.361 mg·g-1). Under different light quality environments, there were significant differences in fruit firmness, and the fruit firmness of the red fruit bag was significantly lower, which was 16.1% lower than white bag control. In addition, other internal quality measurements showed that the indigo fruit bags significantly improved the flavor of the fruits, which improved mainly soluble solids, sugar components and sweetness value. The detection of aroma compounds showed that the blue fruit bag significantly increased the total amount of fruit aroma compounds, which was significantly increased by 2.89 times compared with white bag control. Based on the above indicators, a correlation analysis between light quality and various quality indicators was conducted, and found that there was a close correlation between fruit external quality and light quality. The correlation coefficients between the purple/indigo, orange, and purple/blue values and the L*, a*, and b* values of the peel were 0.901, 0.810, and 0.854, respectively. The internal quality of fruit, such as chlorophyll, total flavonoid, total phenolic and total aroma compounds, were most closely related to blue light, and the correlation coefficients of them with blue light were 0.947, 0.822, 0.851 and 0.757, respectively. 【Conclusion】 According to the comprehensive analysis, purple and blue light were beneficial to improve the external and internal quality of Ruixue apple. Therefore, the transmission amount of purple and blue light could be appropriately increased in the fruit bag during Ruixue bagging cultivation to further improve fruit quality. |
