摘　　要：为了解IAA和IBA对云南松插穗扦插生根的影响,作了不同浓度的IAA和IBA处理采自5年生实生云南松混合家系人工林的当年生穗条的扦插生根效应试验。其试验数据的回归分析表明:在单因素效应中,用以处理云南松插穗的IAA最佳浓度为0.338 g/L,对应的云南松插穗的理论生根率为55.0%;用以处理云南松插穗的IBA最佳浓度为0.215 g/L,其对应的云南松插穗的理论生根率为31.0%;交互效应中,用以处理云南松插穗的IAA和IBA的最佳浓度分别为0.313 g/L和0.163 g/L,其对应的云南松插穗的生根率为63.5%。Taking the cuttings from 5 years old Pinus yunnanensis sapling at Lufengcun Forest Farm of Yiliang county as experimental materials, the effects of IAA and IBA on rooting of cuttings were studied. The results of experiments showed that the optimum concentration of IAA solution was 0. 338 g/L with the theoretical rooting rate of 55.0 % if shoot cutting was only treated by IAA solution, the 0. 215 g/L of IBA has the highest theoretical rooting rate of 31.0 % if only using IBA as rooting regulator, and theoretically, there was the optional rooting rate of 63.5 % for combining IAA and IBA with concentration solution of 0. 313 g/L and 0. 163 g/L respectively.
