摘　　要：为栽培优质丰产的猕猴桃提供参考,以3年生红阳猕猴桃(Actinidia chinensis)为试材,定期测量猕猴桃果实的纵径、横径、鲜果重及体积的变化,探明果实的动态生长发育规律。结果表明:红阳猕猴桃果实纵横径经历快速生长-缓慢生长-停滞生长的变化规律,呈现逐渐上升的单曲线;果实鲜重和体积呈现双S形生长曲线,表现为缓慢生长-快速生长-缓慢生长-快速生长-停滞生长;果实纵径净增长曲线在授粉后15d(4月20日)出现1个生长高峰,果实横径净增长有3个生长高峰,分别出现在授粉后15d(4月20日)、35d(5月10日)和98d(7月12日);果实鲜重净生长量有3个生长高峰,分别出现在授粉后35d(5月10日)、55d(5月30日)和138d(8月22日),果实体积净生长量有2个生长高峰,分别出现在授粉后35d(5月10日)和67d(6月11日)。The variation in longitudinal diameter,transverse diameter,fresh fruit weight and volume of Hongyang Kiwifruit with three years old is periodically measured to discuss dynamic growth and development regularity of kiwifruit and to provide a reference for high quality and high yield cultivation of kiwifruit.Results:The longitudinal and transverse diameter of Hongyang Kiwifruit shows a variation regularity of rapid growth-slow growth-stagnation growth and presents a single gradual rising curve.The fresh fruit weight and volume of Hongyang Kiwifruit show the double S-shaped growth curve,which indicates the sow-rapid-slow-rapid-stagnation growth regularity.The net growth curve of fruit longitudinal diameter presents a growth peak in 15 d after pollination.There are three growth peaks in net growth of fruit transverse diameter and three growth peaks are in 15 d,35 d and 98 d after pollination respectively.Three growth peaks of net growth of fresh fruit weight occur in 35 d,55 d and 138 d after pollination separately.Two growth peaks of net growth of fruit volume occur in 35 d and 67 d after pollination respectively.
