Abstract :

Lilac (Syringa vulgaris) is a valuable shrub used in the landscape due to its beautiful leaves and flowers and pleasant fragrance. Grafting of lilac on wild privet (Ligustrum vulgare) was evaluated in this study to reduce the time required for propagation and the use of rootstock. Stenting or simultaneous rooting and grafting is a novel method for propagating of some woody plants. In this research, the stenting technique was applied to propagate lilac for the first time. Two stenting methods (splice and omega) and three concentrations of IBA (0, 1000 and 2000 mg L^-1) were evaluated. According to the results, stenting via the splice method significantly increased the percentage of rooted stentings and leafed scions and reduced the rate of dried stentings in comparison to the omega method. The percentage of rootstock callus formation, percentage of leafed scions, and fresh weight of produced roots and shoots were significantly enhanced by application of IBA. The best results were obtained with 2000 mg L^-1. In addition, the lowest percentage of dried stenting was observed in this treatment. Also, final success of stenting showed that the use of the splice method and IBA had the highest achievement. In conclusion, the application of 2000 mg L^-1 IBA in comparison with splice stenting method is recommended for propagation of Syringa vulgaris.
