用不同浓度的ＩＢＡ对４个苹果品种的组织培养分化嫩梢进行了不同时间的浸泡处理。结果表明，以ＩＢＡ使用浓度为１００ｍｇ／ｌ处理１２ｈ，置于１／２ＭＳ＋０．１ｍｇ／ｌＧＡ＋１．５ｍｇ／ｌＩＡＡ＋０．５ｇ／ｌ活性碳培养基诱导生根的技术方案最优。红乔纳金等４个苹果品种的平均生根率均达７１．０％以上，最高为９０．８％。
With different concentrations of IBA on four apple cultivars differentiation of young shoots were immersed at different times. The results showed that the optimal solution for inducing rooting with IBA at a concentration of 100 mg / l for 12 h and 1/2 MS + 0.1 mg / l GA + 1.5 mg / l IAA + 0.5 g / l activated carbon medium was used. The average rooting rate of four apple varieties including red Jonathan reached more than 71.0% and the highest was 90.8%.
