经不同生长素、不同浓度的比较试验、筛选出苹果试管苗生根培养的适宜生长素IBA和适宜浓度0.3mg/l或IBA0.3mg/l+NAA0.1mg/l、IBA0.15mg/l+NAA0.15/l双步生根法的综合生根效应优于直接生根培养。采用双步生根法生长素的浓度以IBA1.0mg/l最佳。
The appropriate auxin IBA and appropriate concentration of 0.3mg / l or IBA0.3mg / l + NAA0.1mg / l, IBA0.15mg / l + NAA0 The comprehensive rooting effect of 15 / l double step rooting was better than that of direct rooting. Using two-step rooting auxin concentration IBA1.0mg / l best.
