本实验系1981～1984年,采用西北农学院果树站的成年猕猴桃大树及已开花的幼年嫁接苗的叶片进行的。用联苯胺、愈创树脂等药剂的溶液,分别与猕猴桃雌、雄株的结果枝和发育枝的叶片提取液进行反应,观察反应液的颜色变化和排出气泡的多少,判断过氧化物酶活性的高低,以鉴别雌、雄株。其结果,雄株与药剂作用后,反应液颜色变化比雌株快而深,反应液中排出的氧气量也多。历年试验均表明,雌、雄株反应液均明显不同。
The experiment from 1981 to 1984, using the Northwest College of Agriculture fruit tree station adult kiwifruit trees and flowering young grafted seedlings leaves. The solution of benzidine and guaiac resin was used to react with the extract of the branch and the branch of the female and male plants of kiwifruit to observe the color change of the reaction solution and the amount of the discharged bubbles to judge the peroxidase activity The level of identification of female and male plants. As a result, after the action of the male plant and the agent, the color of the reaction liquid changed faster and deeper than that of the female plant, and the amount of oxygen discharged from the reaction liquid was also large. Tests over the years showed that female and male plant response fluid were significantly different.
