摘　　要：为建立苹果无病毒苗快速繁育体系,以沁源山定子(MalusbaccataBorkh.)、八棱海棠(Malusmicroma lusMak.)营养钵苗和八棱海棠大田直播苗为砧木,脱毒丽红苹果(MaluspumilaMilll.cv.lihong)组织培养芽丛为接穗,采用自然茎尖嫁接法,研究IBA对自然微型嫁接成活率的影响。结果表明,IBA处理可明显提高嫁接成活率。IBA最佳浓度为1 5mg/kg,最高嫁接成活率达81 3%。不同砧木、不同砧苗培养方式,嫁接成活率有差异,以大田直播八棱海棠砧苗效果最好。The effect of IBA on the survival percent of matural micro-grafting were studied in order to establish the fast virus-free apple breeding system.The results showed that the treatments of IBA increased the grafting survival rate obviously.The best concentration was 1.5 mg/kg,and the highest survival percent was 81.3%.There were significance between different rootstocks on different culture methods.The best result was abtained by Malus micromalus Mark.in thd field.
