利用患枣疯病的婆枣组培苗做砧木，健康冬枣组培苗做接穗，进行微嫁接。试验采取加入植物生长素调节、暗培养、嫁接口处理的方法改善砧木的茎粗状况，结果表明暗培养可增加茎粗，增长节间，减少后期除萌，更适用于枣树微嫁接；而加入植物生长调节剂等方法基本无效。试验进行了“婆枣-冬枣”和“冬枣-冬枣”的不同嫁接组合处理，结果表明，嫁接亲和性是嫁接成活的因素之一。试验还对嫁接不同时间的砧穗生长情况进行了跟踪调查，植原体能够从砧木传导至接穗中。%In this research, 'Pozao' (PF) plantlets infected with JWB as rootstock and healthy Dongzao(DF) as scion are used in the micro grafting. The experiment tries employing auxin regulation, darkness and the grafting methods to improve the situation of the stem thickness. The results show that darkness can increase the stem di-ameter and internode and reduce the effort in removing the unwanted sprouts afterwards, while other methods like adding auxin regulation are proved mostly ineffective. Two combinations of scion-rootstock, healthy 'Dongzao' grafted on diseased "Pozao" (marked D/PF) and healthy "Dongzao" grafted on diseased 'Dongzao' (marked D/DF), are compared. The result indicates that genetic relationship has some effect on micro grafting. The rootstocks and scions were observed day by day, and it is found that the JWB phytoplasma was successfully transmitted into the scion from the diseased rootstock.
