| 摘 要： | 以青榨槭为材料,采用L9(33)正交试验研究了生长调节剂α-萘乙酸 (NAA)、吲哚丁酸(IBA)和赤霉素(GA3)对青榨槭扦插生根及生根过程中过氧化物酶(POD)、吲哚乙酸氧化酶(IAAO)和多酚氧化酶(PPO)活性的影响.结果显示:NAA 、IBA和GA3处理均显著提高了青榨槭插条生根率、生根数量和根长,并以NAA的影响最大;400 mg/L IBA+400 mg/L NAA+20 mg/L GA3组合处理的插条生根效果最好,其生根率、生根数和根长分别达88.5%、6条和15.88 cm,分别比无生长调节剂对照显著增加108%、200%和285%;NAA 、IBA和GA3处理可提高青榨槭插穗POD活性,降低IAAO活性,加速PPO活性高峰的出现.研究表明,生长调节剂可以调节青榨槭插穗的POD、IAAO和PPO活性,有效缩短青榨槭插穗生根时间,显著提高其生根率.

| Abstract: | The effects of plant growth regulators on the softwood-cutting rooting of Acer davidii Franch.were studied with the orthogonal design of L9(33)experiments.The dynamic change of activities of peroxidase(POD),indoleacetic acid oxidase(IAAO)and polyphenol oxidase(PPO)during rooting process were also investigated.The results showed that the cutting rooting percentage,the number of roots and the root length increased significantly by the treatment of NAA,IBA and GA3.One of the greatest impact was the NAA,followe... |
