中文摘要:

      通过对库库瓦、伊赛、罗高、安娜、缤果、红色九月、紫色萨多瓦和日内瓦 8个软枣猕猴桃品种的物候期以及生物学特征调查，综合评价了果实外观以及果实内在品质。结果表明，8个软枣猕猴桃品种在北京地区 3月底至 4月初萌芽，5月初至 5月中旬开花，9月下旬至 10月中旬果实成熟；花白色，花冠直径 1.502~2.236cm，花瓣 5~10片，柱头 16~25枚，雄蕊 33~43枚；果实卵形、椭圆和圆柱形，果实重量 8.54~19.5g，可溶性固形物含量 17%~22.7%，Vc含量 43.2~46.6mg/kg。就引种综合表现情况来看，缤果最好，伊赛、红色九月、紫色萨多瓦、罗高、日内瓦和安娜表现较好。

英文摘要:

      After phonological phase and biological characteristics of 8 varieties of Actinidia arguta,including Kokuwa, Issai, Rogów, Anna, Bingo, Red September, Purple Saduwa and Geneva wereinvestigated, the fruit appearance and internal quality were comprehensively evaluated. The results showthat 8 varieties of actinidia arguta sprout from late March to early April, flower from early May to midMay, Fruit ripen from late September to mid-October in Beijing. Flowers are white, with 1.502~2.236cm corolla diameter, 5~10 petals, 16~25 stigmas, 33~43 stamens. Fruits are oval, elliptic and cylindrical,with 8.54~19.5 g weight, 17~22.7% soluble solid, 43.2~46.6 mg/kg Vitamin C. In terms of the overallperformance of the introduced species, Bingo performs best, Issai, Red September, Purple Saduwa,Rogów, Geneva and Anna perform better.
