摘要
研究了不同浓度IBA和IAA对‘粉红佳人’苹果脱毒试管苗生根的影响.结果表明:以1/2 MS和2 g/L活性炭为基本培养基附加IBA 2.0 mg/L处理组的生根率最高,达96.6%;在IAA与IBA的组合中,以IAA 0.5mg/L+IBA 1.0 mg/L处理组的生根率最高,为63.3%,且株高、根长及单株生根数都比单激素IBA处理效果好.
Effect of IBA and IAA was studied on rooting of apple （cv. Pink Lady）in vitro. The results showed that the rooting rate was the highest in 1/2 MS medium and 2 g/L active carbon with IBA 2.0 mg/L,the average rooting rate reached 96.6 %. A combination treatment with IAA 0.5 mg/L and IBA 1.0 mg/L had a higher rooting height ,root length and number rate. The treatment also showed better than single IBA treatment in plant of root.
