Abstract: Rain-sheltered cultivation is an important technical measure to promote peach industry in southern China. In this study, three mid-late maturing peach cultivars, Xiahui No.5, Danxiayulu and Chiyulu were used as test materials to analyze the influence of rain-sheltered cultivation on fruit quality of peach cultivars by using open-field cultivation as the control. The results showed that the rain-sheltered cultivation increased the soluble solid content, solid-acid ratio and sucrose content in the fruits, and especially for late-maturing cultivar Chiyulu, the content of sucrose, fructose and glucose of fruits were significantly higher than that under open-field cultivation. Overall, the contents of total acid and organic acid in fruits of mid-maturing cultivars showed a downward trend after rain-sheltered cultivation, while that of the late-maturing cultivar Chiyulu was the opposite. The rain-sheltered cultivation also increased the content of soluble sugar, soluble protein and anthocyanin in the peels, meanwhile, the contents of total phenols and flavonoids of the peels reduced. In addition, the rain-sheltered cultivation also caused the average fruit weight and color parameters of some cultivars to decrease obviously. Therefore, compared with the open-field cultivation, the rain-sheltered cultivation could significantly improve the flavor quality of the peach fruits, but at the same time it also had some adverse effects on the yield and appearance coloring of the fruits to some extent. Rain-sheltered cultivation techniques should be optimized and adjusted in full consideration of cultivar characteristics and specific weather conditions.
