Evaluation storage capacity of six kind late-maturing Actinidia arguta resources

Actinidia arguta has a high edible value, nutritional value, and abundant resources; however, it is not durable. The selection of late-maturing, durable storage resources is one idea for solving this problem. Through phenological observations, we identified six types of late-maturing resources as experimental materials in this experiment, named CJ No.10, CJ No.6, CJ No.7, CJ No.9, CJ No.3, and CJ No.8, and compared the sensory, physicochemical, nutritional quality, and taste changes during storage to determine durable storage resources. The specific conclusions are as follows: at the end of storage, CJ No.8 and CJ No.7 had good sensory and physicochemical qualities, with high Vc and SSC content in CJ No.3, high total phenol, and flavonoid content in CJ No.8, high TA residual content in CJ No.9, and higher reducing sugar content in CJ No.7 and CJ No.10. Correlation analysis showed that the weight loss rate was positively correlated with the decay rate and sweet taste value and negatively correlated with flavonoid content and firmness. PCA showed that the differences in the storage capacity of all resources were mainly related to firmness, sensory score, weight loss rate, sweet taste, Vc, and SSC. The PCA scores showed that CJ No.8 had better storage resistance than the other resources. CJ No.8 could be promoted as a high-quality late-mature storage-resistant variety to promote the sustainable development of A. arguta industry.
