Propagation of rose varieties by cuttings under the effect of different rooting hormones

Roses are one of the oldest and perhaps most noble and beautiful plants in the world. The propagation of roses by stem cutting is the simplest and a largely used method to multiply them. For the present experiment, seven varieties of roses were selected as follows: ‘Monika’, ‘Mr. Lincoln’, ‘Queen Elisabeth’, ‘The Fairy’, ‘Peace’, ‘King’s Ransom’, and ‘Don Juan’. To assess the differences between the varieties, growth, root length, root number, and frost damage were determined. The aim of the experiment is to determine which rose varieties are better suited to propagation by cuttings, which varieties have a higher rooting tendency, and to what extent the rooting could be influenced by rooting hormones [Incit-8 (0.8% of 1-Naphthaleneacetic acid) and Radi-Stim^®]. From our results, it could be determined that the Incit-8 positively influenced the number of roots of all varieties. In conclusion, our research suggests that the rooting hormones increase the rooting of the rose varieties; moreover, that proper rooting could also be depending on the appropriate conditions.
