为扦插繁殖技术在难生根树种核桃上的应用提供依据，以5年生清香核桃为试材，采用双层基质弥雾繁殖箱繁殖法，研究外源激素对清香核桃插穗愈伤组织及根系形成的影响。结果表明：单一外源激素处理，IBA 浓度为100 mg／kg 时，出愈时间和出愈率最短与最大，分别为29 d 和25．8％。ABT1号生根粉浓度为100 mg／kg 时，出愈时间最短、出愈率最高和生根时间最短，分别为24 d、28．7％和49 d；根长、根系粗度和根系质量最长／粗／好，分别为5．9 cm、2．8 mm 和0．52。IBA＋ABT1组合处理浓度为100 mg／kg＋200 mg／kg时，出愈时间、生根时间和出愈率分别为14 d、38 d 和39．8％；根长、根粗和根系质量分别达8．1 cm、4．4 mm 和0．75。IBA＋ABT1组合处理效果较单一 IBA 处理好。

The effect of exogenous hormone on formation of cali and roots of cuttings of Qingxiang J .regia with 5 years old was studied by bi-layer substrate mist spraying propagation method to provide the scientific basis for application of cutting propagation technique in J .regia.The callus formation time and callus rate of cuttings treated with IBA(100 mg/kg)are 29 d and 25.8% respectively.The callus formation time,callus rate,rooting time,root length,root diameter and root quality index of cuttings treated with ABT1(100 mg/kg)are 24 d,28.7%,49 d,5.9 cm,2.8 mm and 0.52 separately.The callus formation time,rooting time,callus rate,root length,root diameter and root quality index of cuttings treated by IBA(100 mg/kg)+ ABT1 (200 mg/kg)are 14 d,38 d,39.8%,8.1 cm,4.4 mm and 0.75 respectively,which indicates that the effect of IBA+ ABT1 treatment on formation of cali and roots of cuttings of Qingxiang J .regia is better than single IBA treatment.
