【摘要】 [目的]筛选黎蒴扦插繁殖最优组合。[方法]以生长健壮的2年生黎蒴苗为试材，采用正交试验设计，分析不同激素、不同基质组分对扦插成活率、愈伤组织生长、芽生长率的影响，并筛选出最优组合。[结果]砂壤土利于插穗苗的扦插生长，插穗成活率为86.30%,2种激素处理对插穗苗扦插生长差异不大，NAA处理成活率为72.59%,IBA处理成活率为65.19%;砂壤土对愈伤组织生长的影响最大，插穗愈伤组织生长率为65.56%,2种激素处理对愈伤组织生长的影响无明显差异，NAA处理为50.74%,IBA处理为48.89%;黄心土为基质的芽生长率最高，为28.89%,2种激素处理对芽生长率无明显差异，NAA处理为25.56%,IBA处理为21.11%。[结论]扦插基质最优处理为砂壤土与CK的组合。更多还原

【Abstract】 [Objective]To select the optimal combination of cutting propagation of local tree Castanopsis fissa. [Method]The effects of different hormones and substrate components on the survival rate, callus growth and bud growth rate of cuttings were analyzed by orthogonal experiment. [Result]The results showed that sand loam was the best for cutting growth of cuttings, and the cuttings survival rate was 86.30%. There was little difference between the two hormone treatments on cutting growth of cuttings, the survival rate of NAA treatment was 72.59%, IBA treatment was 65.19%. The callus growth rate of cuttings was 65.56% in sandy loam soil. The callus growth rate of cuttings was 65.56% in sandy loam soil. The callus growth rate of cuttings was 50.74% in NAA treatment and 48.89% in IBA treatment. The shoot growth rate was the highest in yellow heart soil, which was 28.89%. There was no significant difference in the shoot growth rate between NAA and IBA treatments, which was 25.56% and 21.11% respectively. [Conclusion]The optimal cutting matrix combination was sandy loam and CK.更多还原
