不同植物生长调节剂对铁线莲‘Andromeda’扦插生根及生理的影响

以铁线莲品种Clematis （ Andromeda）半木质化枝条为材料，分别用不同浓度的萘乙酸（ NAA）和吲哚丁酸（ IBA）进行处理，清水作对照，研究不同植物生长调节剂对铁线莲的扦插生根能力和生根过程中POD、SOD、 PPO氧化酶活性的影响。结果表明：清水处理的插穗生根率最高为32.27％，明显高于植物生长调节剂处理的插穗。铁线莲扦插生根过程中POD、SOD、 PPO酶活性也随扦插生根不同表现出升高或降低的动态变化，其中对照组插穗的酶活性普遍较高。

Effects of Plant Growth Regulators on Cuttings of Rooting and Physiology of Clematis ‘Andromeda’

As experimental materials, semi-lignified branches of Clematis ‘Andromeda’ were treated with acetic acid （ NAA） and indole butyric acid （ IBA） by using different pH indicator.Compared with treatment by only using fresh water, the research was focused on the effects of plant growth regulators on the cuttings of rooting of Clematis （Andromeda） and enzyme activity of POD, SOD and PPO during the cuttings of rooting process.The result showed that the highest rate of the cuttings of rooting of Clematis （ Andromeda） by using fresh water was 32.27 %, which was much higher than the rate of using the plant growth regulators.During the cuttings of rooting process, the en-zyme activity of POD, SOD and PPO showed dynamic changes, in terms of rising or reducing.Generally in the con-trol group the enzyme activity of POD, SOD and PPO during the cuttings of rooting process was high.
