软枣猕猴桃(Actinidia arguta Pl-anch·),是猕猴桃属中,在我国地域分布最广的珍贵野生果树资源之一。其中,东北三省资源最为丰富,仅辽宁省蕴藏量就高达5400吨左右。它的果实柔软多汁,酸甜可口,芳香浓郁,维生素 C 含量高(100～420mg/100g),保健效果好,已引起人们的高度重视。软枣猕猴桃雌雄异株,大藤本。自然类型繁多,果型多样,经济性状各异。为优良单株选择提供了丰富的种质资源。优良单株扩大繁殖,只能用无性繁殖,因有性繁殖不能保持优良单株的遗传性状。我们研究种子繁殖的主要目的,就在于为扩大优良单株繁殖提供嫁接所需的砧木。现将试验结果报告如下。
Actinidia arguta Pl-anch · is one of the most valuable wild fruit resources in the genus Actinidia in China. Among them, the three northeastern provinces have the most abundant resources, and the reserves in Liaoning Province alone are as high as 5,400 tons. Its soft and juicy fruit, sweet and sour and delicious, rich aroma, high vitamin C content (100 ~ 420mg / 100g), good health effects, has attracted people’s attention. Soft jujube Kiwi dioecious, large vine. Natural variety, fruit variety, economic traits vary. For a fine selection of plants provides a wealth of germplasm resources. Excellent single plant to expand reproduction, can only be asexual reproduction, sexual reproduction can not maintain the genetic characteristics of fine plants. The main purpose of our study on seed multiplication lies in the supply of rootstocks needed for grafting to expand fine individual plants. The test results are reported below.
