摘要：

为研究大阪松的扦插影响因子,本试验以微型金针大阪松枝条为材料,研究了插穗类型、扦插基质、生长调节剂种类与质量浓度、生长调节剂施用方式对其扦插生根的影响。结果表明,促进金针大阪松扦插生根的最佳方法是以半木质化枝条为扦插材料,使用200 mg·L^-1吲哚丁酸(IBA)溶液处理,或采用含1 500 mg·L^-1 IBA泥浆蘸裹插穗,然后在泥炭土、黄心土、珍珠岩质量比为2∶1∶2的基质中扦插。

Abstract:

To study the influencing factors of Pinus parviflora cutting, the branch of minitype P. parviflora Aurea was used as material. The effects of cutting types, propagation substrates, varieties and mass concentrations of growth regulators, and application methods of growth regulators on root development were investigated. The result indicated that the best method to promote rooting in cuttings of P. parviflora Aurea was to use semi-woody cuttings treated with 200 mg·L^-1 indole-3-butyric acid(IBA), or to dip the cuttings in 1 500 mg·L^-1 IBA and took cuttings in the substrate mixture of peat soil, yellow soil, and perlite in a mass ratio of 2∶1∶2.

Key words: Pinus parviflora Aurea, cutting propagation, substrate, growth regulator
