Abstract: 【Objective】 To clarify the differences in fruit quality of sweet cherries under different cultivation modes in sunlight greenhouses and provide theoretical basis for research and scientific management of sweet cherry cultivation in sunlight greenhouses in northern Xinjiang. 【Methods】 This study focused on the main variety of sweet cherry Meizao grown in a sunlight greenhouse in northern Xinjiang. Comparing upright and one-sided modes of 24 quality indicators during fruit ripening were measured, and core indicators were selected through variance analysis, correlation analysis, and principal component analysis. A comprehensive quality evaluation model was established using Analytic Hierarchy Process (AHP). 【Results】 The results showed that there were differences in various indicators of sweet cherry fruit under different cultivation modes, among which sweetness value, edible rate, total acid, a^*, and glucose were the core indicators for evaluating the quality of sweet cherry fruit; A sweet cherry fruit quality evaluation model Y (comprehensive score)=0.121 was established using the Analytic Hierarchy Process (AHP) × Standardized value of edible rate+0.075 × The standardized value of a^*+0.199 × Normalized sweetness value+0.068 × Normalized value of total acid content+0.037 × Standardized value of glucose content. 【Conclusion】 The evaluation results show that the comprehensive fruit quality of the upright cultivation mode is relatively better than that of the one sided cultivation mode.
