[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 from leaf size, and leaf size can be used as the main basis for judging the quality of fruit.展开更多
