Its fruits crack longitudinally when fully ripe and should be harvested before fruit cracking. Physicochemical characteristics and nutritional composition of the ripening process are prerequisites to establishing proper harvest maturity windows. In the current study, we have investigated the fruit quality characteristics of two A. trifoliata clonal lines \(�Luqing?and �Luyu�\) that were harvested at four time points \(S1: 120 days after full bloom \(DAFB\), S2: 134 DAFB, S3: 148 DAFB, S4: 155 DAFB\). An increase in fruit size \(fruit weight, fruit length, and fruit diameter\) was associated with delayed harvest maturity. The firmness of A. trifoliata fruit exhibited a decreasing trend with delaying the harvest stage. In particular, the firmness decreased sharply from S2 to S3 stage. The TSS, fructose, and glucose content in A. trifoliata fruit continuously increased from the S1 to S4 stage and accumulated sharply from S2 to S3 stage. However, the sucrose and starch content showed an increasing trend from the S1 to S2 stage but declined sharply in the S3 or S4 stage. Ascorbic acid progressively increased with the advancement of A. trifoliata maturity stages, while total phenolics and total flavonoids levels declined with fruit ripening. Considering the results of all quality parameters mentioned above, the A. trifoliata fruit harvested at the S3 maturity stage was the ideal harvest maturity for long-distance transportation and higher consumer acceptability before fruit cracking. Our research reveals the dynamic changes in physicochemical characteristics and nutritional composition during fruit ripening of A. trifoliata. Results in this study reflect the importance of maturity stages for fruit quality and provide basic information for optimal harvest management of A. trifoliata.)/Title(Physicochemical Characteristics and Nutritional Composition during Fruit Ripening of Akebia trifoliata \(Lardizabalaceae\))>>
