狗枣猕猴桃果实生长发育的研究

Studies on the Fruit Development of Actinidia kolomikta

狗枣猕猴桃果实重量和体积同步增长 ,生长曲线为“双S”型 ,纵、横径生长曲线为“S”型。果实发育期主要营养成分 (有机酸、蛋白质、氨基酸、碳水化合物、维生素C等 )含量呈规律性变化 ,授粉后 5 0d左右 ,各项营养指标达到较适宜程度 。

Results of regularly observing and measuring the increase of fruit weight and volume of Actinidia kolomikta Maxim. showed the weight and volume were increased synchronously, and their growth were like a double “S”curve; and the growth curve of length and breadth was a shape of “S”.The contents of the main nutritive ingredients, including organic acid, protein, amino acid,carbohydrate, vitamin C and so on,changed regularly. Around 50 days after pollination each nutritive index was up to the appropriate degree, and entered the picking period.
