Abstract: The research aimed to explore the correlation between fruiting branch diameter of A. chinensis and fruit quality change during the post-ripening period and the mechanism, which could provide theoretical basis for making scientific management measures during A. chinensis fruit post-ripening period. In this paper, correlation analysis between fruiting branch diameter of A. chinensis and fruit quality change during post-ripening period during 2013-2015 was conducted. Results were as below: (i) correlation coefficient analysis showed that fruiting branch diameter was highly positive correlation with number of fruit ventricle, significantly positive correlation with single fruit weight when picking and the indexes after the fruit ripening single (single fruit weight, loss rate of single fruit weight, longitudinal diameter of fruit and width of fruit core), lowly positive correlation with sugar content of fruit juice, and positive correlation with thick transverse diameter of fruit after ripening. (ii) Standard errors of regression analysis between fruiting branch diameter and single fruit weight, longitudinal diameter of fruit, wide transverse diameter of fruit, thick transverse diameter of fruit, fruit core length and sugar content of fruit juice were 12.4248, 4.2731, 2.6452, 2.0260, 0.1337 and 1.0035 respectively; significance F values of variance analysis were 0.0743, 0.0658, 0.1950, 0.5733, 0.2600 and 0.1517 respectively. It showed that fruiting branch diameter had a significant difference with thick transverse diameter of fruit and insignificant differences with other indicators; quadratic curve regression equation and linear regression equation of residual curve, observed value curve, forecast value curve and normal probability curve of were analyzed, and the results were all in line with the law of quadratic curve. (iii) The larger the fruiting branch diameter, the greater the indexes after post-ripening (single fruit weight, longitudinal diameter of fruit, wide transverse diameter of fruit, thick transverse diameter of fruit and sugar content of fruit juice), the better the fruit quality. It was clear that fruiting branch diameter could be as one of important bases of fruit quality change during post-ripening period. Through investigating fruiting branch diameter and the regression equation, it could predict single fruit weight, longitudinal and transverse diameters of fruit, and sugar content of fruit juice index after the ripening.
