This study was conducted to investigate the effect of different concentrations (0, 1500, 3000, 4500 mg/L) of Indole-3-butyric acid (IBA) on propagation of three cultivars of Rosa hybrid L. ('Dolce Vita', 'Samurai' and 'Utopia') by stenting (simultaneous cutting and grafting) method under greenhouse conditions. The cultivars were grafted onto Rosa hybrida L. 'Natal Briar' rootstock. The factorial experiment was performed in a completely randomized design with three replications. The stentings were cultured in coco peat and perlite medium at 1:2 ratio in a greenhouse under mist system. After 60 days, the percentage of grafting, rooting percentage, root number, longest root length and fresh and dry weights of roots and shoot traits (including leaf number, shoot number, and longest shoot length) were determined on the stentings. The highest rate of rooting in Dolce Vita cultivar was obtained at 1500 mg/L IBA and in Samurai and Utopia cultivars at 4500 mg/L IBA. Among the three cultivars of roses, highest percentage of rooting (93.75%), healing percentage (93.75%), root length (12.47 cm), fresh weight (0.84 g) and dry weight (0.07 g) of roots were observed in stentings treated with 4500 mg/L of IBA in Rosa hybrida L. cv. Samurai. Interaction between IBA concentrations and cultivars on chlorophyll (a, b and total) and carotenoid contents were significant in all the three cultivars of roses.}, keywords = {Cutting-graft,Indole-3-butyric acid (IBA),root,Rootstock,Roses}, url = {https://ijhst.ut.ac.ir/article_75265.html}, eprint = {https://ijhst.ut.ac.ir/article_75265_9e18d33756c1b7fa0ffd6aa913cb0b36.pdf} }
