In order to solve the problem of low rooting rate of apple cuttings,one year old Fuji,Melba and Malus robusta Rehd cuttings were used as materials to study the effects of rejuvenating trunk buried combined with IBA treatment on rooting.The results showed that the rooting rate,rooting number,root length and rooting index of rejuvenated trunk of Fuji,Melba and Malus robusta Rehd cuttings that grew in the medium with cow dung and loam mixed in a ratio of 2∶3 were all higher than those of the nonrejuvenated trunk. With the increase of IBA concentration,the four indexes all showed the trend of first rising and then declining.When IBA concentration was 1 250 mg/L,the rooting rate,rooting number,root length and rooting index were the highest.The rooting rates were 91.8%, 90.8% and 93.1%,respectively.The rooting numbers were 25.8,45.8 and 39.2.The root lengths were 60.6,60.3,48.8mm.The rooting indexes were 145.0,250.2 and 177.7.This study found that combination of rejuvenating trunk buried with IBA treatment could greatly improve the rooting rate of apple cuttings and achieve rapid and efficient cloning of apple cultivar.
