摘　　要：[Objective] This study aimed to investigate the effect of leaf size on fruit quality of kiwi and relevant mechanism. [Method] The correlation between leaf shape and fruit quality of kiwi was studied during 2013-2015. [Result] The results of statistical analysis showed that the sing weight, longitudinal diameter, width, thickness, shape index and juice sugar content of fruit were 75.86±1.68 g, 73.284± 0.70 mm, 41.18±0.51 mm, 35.30±0.25 mm, 1.92±0.01 and （15.66±0.26）%, respec- tively; the length, width, shape index and area of leaf were 14.77±0.20 cm, 14.25± 0.16 cm, 0.94±0.09 and 152.39±3.26 cm^2, respectively; and the length and diameter of petiole were 11.03±0.25 cm and （31.50±0.79 mm）/10, respectively. The results of correlation analysis showed that the single fruit weight of kiwi was strongly positively related to fruit longitudinal diameter, fruit width, fruit thickness and leaf shape index, was significantly positively related to leaf length, was weakly positively related to petiole length, was positively related to leaf area, was weakly negatively related to leaf width and petiole diameter, and was negatively related to juice sugar content. The results of regression analysis showed that there was significant difference be- tween single fruit weight and juice sugar content （F=0.851 8, P〈0.01）, instead of fruit longitudinal diameter （F=0.000 6, P〉0.05）, fruit width （F=0.001 4, P〉0.05） and fruit thickness （F=0.005 4, P〉0.05）; there was significant correlation between single fruit weight and leaf area （F=0.671 5, P〈0.01）, instead of leaf length （F=0.139 3, P〉0.05）, leaf width （F=0.358 5, P〉0.05） and leaf shape index （F=0.294 0, P〉0.05）; there were significant correlations between juice sugar content and leaf length （F= 0.816 1, P〈0.01）, leaf width （F=0.970 1, P〈0.01）, leaf area （F=0.560 6, P〈0.01） and leaf shape index （F=0.885 1, P〈0.05）. [Conclusion] Fruit single weight and oth- er quality properties could be predicted [目的]探讨影响猕猴桃果实品质变化的相关性及机理,并为制定科学的猕猴桃栽培技术提供理论依据。[方法]2013~2015年对猕猴桃叶形与果实品质特性的相关性进行调查研究。[结果](1)统计分析:猕猴桃果实(单果重、纵径、宽横径、厚横径、果形指数和果汁含糖量)、叶片(长度、宽度、叶形指数和面积)和叶柄(长度和直径)等内容分别为(75.86±1.68 g、73.28±0.70 mm、41.18±0.51 mm、35.30±0.25 mm、1.92±0.01和15.66±0.26%)、(14.77±0.20 cm、14.25±0.16 cm、0.94±0.09和152.39±3.26 cm^2)和(11.03±0.25 cm和31.50±0.79 mm/10)。(2)相关系数分析:猕猴桃果实单果重与果实纵径、果实宽横径、果实厚横径和叶形指数等内容呈高度正相关,与叶片长度呈显著正相关,与叶柄长度呈低度正相关,与叶面积呈正相关,与叶片宽度和叶柄直径等内容呈低度负相关,与果汁含糖量呈负相关。(3)回归分析:(果实单果重与果实纵径、果实宽横径、果实厚横径和果汁含糖量):显著性F分别为0.000 6、0.001 4、0.0054和0.851 8,即果实单果重与果汁含糖量之间存在差异极显著,与其它内容之间存在差异不显著;(果实单果重与叶片长度、叶片宽度、叶形指数和叶面积):差异水平分别为0.1393、0.358 5、0.294 0和0.671 5,即果实单果重与叶面积之间存在差异极显著,与其它内容之间都存在差异不显著;(果汁含糖量与叶片长度、叶片宽度、叶形指数和叶面积):差异水平分别为0.816 1、0.970 1、0.560 6和0.885 1,即果汁含糖量与叶片长度、叶片宽度和叶面积等内容之间都存在差异极显著,与叶形指数之间存在差异显著。[结论](1)通过调查叶片大小来预测果实单果重等品质特性;(2)可以叶片大小作为判断果实品质优劣的主要依据之一。
