摘　　要：[目的]研究贵长猕猴桃果实生长发育规律。[方法]以4年生贵长猕猴桃为试验材料,定期测量果实的纵径、横径、鲜果重,干物质含量及水分含量,探明果实动态生长发育规律。[结果]贵长猕猴桃果实纵横径经历了快速生长—缓慢生长—停滞生长—缓慢生长的变化规律,呈现逐渐上升的单曲线;果实鲜果重表现为缓慢生长—快速生长—缓慢生长—快速生长—停滞生长—缓慢生长的变化规律,呈现逐渐上升的"双S"曲线;果实纵横径的日均生长曲线变化基本一致,授粉后15 d(5月10日)内日均增长量最大,后逐渐下降,趋近于0,后又有所上升、最后再下降;果实鲜果日均生长量,有4个生长高峰,分别为授粉后15~25 d(5月10—20日)、46~57 d(6月11—22日)、67~77 d(7月2—12日)、118~128 d(8月22日—9月1日);果实98 d的生育期内,水分的含量都在80%以上,干物质最高占17.13%。[结论]该研究为制定贵长猕猴桃优质高产栽培技术措施提供参考。[Objective]To research the growth and development regularity of Guichang kiwifruit.[Method]With four-year-old Guichang kiwifruit as the test materials,the fruit longitudinal diameter,transverse diameter,fresh fruit weight,dry matter content,moisture content of Guichang kiwifruit were detected.And the dynamic growth and development regularity of kiwifruit were researched.[Result]The longitudinal and transverse diameter of Guichang kiwifruit showed a variation regularity of rapid growth-slow growth-stagnant growth-slow growth and presented a single gradual rising curve.The fresh fruit weight of Guichang kiwifruit show the double S-shaped growth curve,which indicated the slow growth-rapid growth-slow growth-rapid growth-stagnant growth-slow growth variation regularity.The daily growth curve of longitudinal and transverse diameter was basically the same,and the growth was the largest in 15 d after pollination,then decreased gradually,approached 0,increased,and at last decreased.There were four peaks in daily growth curve of fresh fruit weight,and the four peaks occurred in 15-25 d,46-57 d,67-77 d,118-128 d after pollination.During the 98 d of fruit growth,the moisture content was all above 80%,and the highest dry matter was 17.13%.[Conclusion]This research provided references for establishing high quality and high yield cultivation measures of Guichang kiwifruit.
