Abstract:
Taking nectarine triploidy germplasm ‘05-22-49’ as material，key factors were selected by orthogonal test，types and content of auxins were decided by double factor test，in order to establish the propagation method of triploidy nectarine from hardwood cuttings.The results showed that culture condition was the most important factor for rhizogenesis，and water rushing was more important for survival rate of transplanting.Optimized integrative protocol for triploidy nectarine propagation form hardwood cutting was as follows：cutting basal tissues be washed for 24 h in running water，then be treated as follows：diped in 1 000 mg/L IBA solution，inserted into mix medium (perlite∶peat=3∶1)，maintain a temperature of 19℃ around the basal portion of the cuttings and upper part remains exposed to the cooler ambient temperature for 6 days，cultured in solar greenhouse without heating facilities.By the protocol，cuttings survival rate could up to 82%.Immersing cutting basal tissues in low content IBA solution was not better than dipping.ABT（1） rooting powder was an alternative type auxin of IBA for their similar rooting rate.
