    Relationship Between the Changes of Activities and Isoenzymes of Polyphenol Oxidase and the Rooting of Eucalyptus Cuttings After Treatment with Naphthylacetic Acid

      摘要
    • 摘要: 尾叶桉MLA无性系（简称MLA）为难生根植物，尾叶桉U6无性系（简称U6）和刚果12号桉W5无性系（简称W5）为相对易生根植物。MLA插条内的PPO活性比U6、W5的低。用萘乙酸（NAA）处理桉树的插条后，在扦插生根的不同阶段，插条内的PPO活性呈现规律性的变化。蛋白质含量呈上升趋势。文章讨论了多酚氧化酶与桉树插条生根的关系。

       

      Abstract: Eucalyptus urophylla Blade MLA clone (MLA) was a difficult to root species. E. urophylla Blade U 6 clone (U 6) and E. ABL 12 W 5 clone (W 5) were relatively easy to root species. The activity of polyphenol oxidase (PPO) in MLA was lower than that in U 6 and W 5. After the cuttings of Eucalyptus were treated with naphthylacetic acid (NAA), the activities of PPO increased regularly in different stages of rooting. The relationship between the oxidase and rooting of Eucalyptus cuttings was discussed.
