摘要
软枣猕猴桃(Actinidia arguta Planch.)主要在我国东北、华北有部分分布。抗寒性极强,果实品质优良,酸甜适口,风味独特,营养丰富,富含维生素C,是一种经济价值高、发展前途广的野生果树。目前尚无大面积人工栽培。我们从60年代初进行软枣猕猴桃选种工作,以期获得丰产、优质、抗逆性强,适于加工与鲜食的栽培品种。
‘Kui Lu’ is a new cultivar selected from the wild species Actinidia arguta Planch, at Fuxing Forestry Center, Ji An county, Jilin Province in 1980. The plant is dioecious. The fruit is green, oblate with a shape index of 1.32. The average fruit weight is 18.lg, the largest attaining 32.0g. The soluble solids, organic acid, vitamin C and total free amino acids in the fruit juice are 15%, 1.5%, 430mg and 933.8mg per l00g, respectively. Fruit set is 95%. The rate of bud break is 57.6%. 49.2% of the shoots are fruiting shoots.
For a 8-year-old plant, fruit yield may be as high as 13.2kg, equivalent to 954.6 kg/1000m2.
This new cultivar is cold resistant and can survive a low temperature of -38.0℃ . The growth period from bud break to fruit ripening is 120 days. It is suitable to be grown espe-cially at high latitude where winter is severe and frost-free period is short.
