摘要： 为了探讨影响猕猴桃果实在后熟期品质变化的相关性及机理，并为制定科学猕猴桃果实后熟期管理措施提供理论依据。连续3年（2013-2015年）对猕猴桃不同单果重与其后熟期品质变化的相关性进行调查研究。相关系数分析：采果时果实单果重与后熟后（果实单果重和果实横径）等内容呈高度正相关，与后熟后果实纵径和果汁含糖量等内容呈显著正相关，与果实单果重损失率和果实纵径损失率等内容呈正相关，与果实横径损失率呈负相关。回归分析（采果时单果重与后熟后果实单果重、果实纵径、果实横径、单果重损失率、果实纵径损失率、果实横径损失率和果汁含糖量）：方差分析，采果时单果重与后熟后果实横径损失率之间存在差异极显著，与后熟后果实纵径损失率之间存在显著差异，与其他内容之间差异不显著；对残差曲线、观察值曲线、预测值曲线和正态概率图曲线等内容做二次曲线回归方程和直线回归方程的比较分析，其结果都符合二次曲线规律。通过调查采果时果实单果重和回归方程来预测果实后熟后的果实单果重等内容；把果实单果重作为猕猴桃果实后熟期品质变化的重要依据之一。

Abstract: In order to explore influence the correlation of kiwi fruit the maturation period and the quality change and its mechanism,and to develop kiwi fruit ripening period scientific management measures to provide theoretical basis.Three consecutive years(2013-2015)of kiwi fruit weight and different period following the quality change of correlation study.The correlation coefficient analysis:to gather the fruit cooked after fruit weight and fruit,fruit weight and fruit diameter is highly correlated to the content,such as longitudinal diameter and after ripening fruit and fruit juice sugar content was significantly positively related,with the longitudinal diameter of fruit weight loss rate and fruit loss rate,etc were positively correlated,and negatively correlated with fruit diameter loss rate. Regression analysis(to gather the fruit weight and fruit weight,fruit cooked after longitudinal diameter,fruit width,fruit weight loss rate,fruit weight,fruit diameter losses longitudinal diameter and fruit juice sugar content):analysis of variance,and to gather the fruit weight and fruit cooked after transverse diameter extremely significant difference between the loss rate,and after ripening fruit exist significant differences between longitudinal diameter loss rate,and no significant differences between other content;On residual curve,observation value curve and forecast curve and normal probability graph curve etc do conic regression equation and linear regression equation of comparative analysis,the results are in line with the law of quadratic curve. Through investigation to gather the fruit weight and the regression equation to predict after the ripening of fruit weight and other content;The weight of fruit as a kiwi fruit ripening period and the quality change of one of the important basis.
