This study aimed to evaluate the effect of putrescine (PUT) on the rooting of GF677 cuttings under mist condition. Treatments used include PUT concentrations (2 and 4 mM for 5 minutes), indole-3-butyric acid (IBA) using the quick dip method (1500 nad 3000 mg/l for five seconds), and a commercial rooting powder and control (without any rooting substances). Treatments were applied at the end of the dormant season. Growth data were obtained 120 days after the treatments. The results showed that application of 1500 mg/l of IBA and commercial rooting powder improved GF677 rooting, but 3000 mg/l of IBA resulted in toxic effects on rooting anjd foliage of the cuttings. Cuttings treated with PUT solutions showed the best roots and shoots in terms of the number and quality. In conclusion, IBA may be replaced by PUT in the rooting process of GF677 cuttings.
