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的插条内的过氧化物酶(POD)活性较U6、W5的高。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POD活性呈现规律性的变化。POD同工酶谱带也随生根的进程出现增多现象。本文讨论了过氧化物酶与桉树插条生根的关系。

关键词: 过氧化物酶, 桉树, 扦插生根

Abstract: Eucalyptus urophylla S. T. Blade MLA clone(MLA) was difficult-to-root species. E. urophylla S. T. Blade U6 clone(U6) and E. ABL 12 W5 clone(W5) were relatively easy-to-root species. The activities of peroxidase(POD) in MLA were higher than that in U6 and W5. After the cuttings of Eucalyptus were treated with naphthylacetic acid(NAA), the activities of POD increased regularly in different stages of rooting. The relationship between peroxidase and rooting of Eucalyptus cuttings was discussed.

Key words: peroxidase, Eucalyptus, rooting of cuttings
