用聚丙烯酰胺凝胶电泳方法，测定了猕猴桃不同种、不同器官、雌雄株以及嫁接苗与组培苗的过氧化物同工酶，对酶谱特征进行了分析。结果表明，美味猕猴桃（海沃德为代表）与中华猕猴桃（皖蜜为代表）叶片虽有共同的酶带，但都有自身酶谱的特异性。美味猕猴桃不同器官酶谱也具有特异性；猕猴桃雌雄株没有发现特殊的“性酶带”，但是雄株酶带活性明显高于雌株；中华猕猴桃嫁接苗与组培苗酶谱差异无规律可循。 By using polyacrylamide gel electrophoresis, the peroxidase isozymes of different species, organs, male and female plants, grafted seedlings and tissue culture seedlings of Actinidia chinensis were determined. The results showed that the common enzyme bands were found in the leaves of the delicious kiwifruit (represented by Hayward, represented by Wankuangui), but unique in their own zymogram. There were no specific “zygotes” in the male and female plants of Actinidia chinensis, but the zygosity of the male plants was significantly higher than that in the female plants. Follow.
