我国特产果树果中佳品猕猴桃,但它是雌雄异株,苗期又很难鉴别,假如定植后,雄多雌少,会给生产带来很大损失。我省信阳市林科所1978年建园,80年开花结果,其中雄株占87％,雌株仅占13％,严重影响了产量。为此,信阳市农、林科研人员,通过多数样本,重复试验,得出鉴别猕猴桃雌雄株的方法,操作方便,设备简单,可供试验、推广。其方法为: (一) 测试材料:一类用性成熟的雌雄株叶片;另一类用幼令未结果的实生苗叶片。 (二) 测试药剂:1号液为6.93％硫酸铜水溶液;2号液为34.6％苛性钠水溶液。 (三) 测试方法:在植株上各取鲜叶20克,用蒸馏水洗净,研碎,放入烧杯内加200毫升蒸馏水,振荡1—2分钟,浸泡24小时,过滤得叶组织液。
China’s specialty fruit tree fruit kiwi, but it is dioecious, it is difficult to identify the seedling stage, if the colonization, more male and less male, will produce a great loss. Forestry Department of Xinyang City, built in 1978 in 1978, 80 years flowering, of which 87% of male and female plants accounted for only 13%, seriously affected the yield. To this end, Xinyang City, agriculture, forestry researchers, through the majority of samples, repeated tests to identify male and female Kiwifruit identification methods, easy to operate, simple equipment for testing and promotion. The method is as follows: (a) test materials: a class of sexually mature male and female leaves; the other with young seedlings did not result in the seedlings. (B) test agents: No. 1 solution was 6.93% copper sulfate aqueous solution; No. 2 solution was 34.6% caustic soda aqueous solution. (C) Test Method: Take 20 grams of fresh leaves on the plants, washed with distilled water, crushed, placed in a beaker plus 200 ml of distilled water, shaking 1-2 minutes, soaked for 24 hours, filtered leaf tissue fluid.
