Abstract :

In order to study the effect of different indole butyric acid (IBA) concentrations and rootstocks on propagation of rose by stenting technique, an experiment was conducted as a factorial design based on completely randomized design with three replications. First factor was rootstock (Rosa canina L., R. indica var. Major, R. multiflora L.) and second factor was 11 IBA concentrations including 0, 25, 50, 250, 500, 1000, 1500, 2000, 3000, 4000, 5000 ppm. The results showed that in R. indica ‘Major’ rootstock and 25 ppm IBA had highest rooting percentage. Maximum root number was observed in R. Indica ‘major’with 25 and 500 ppm IBA and the minimum number belonged to the control. High callus production was observed in 0, 5000 and 2000 ppm IBA. R. multiflora L. had highest shoot length compared to other rootstocks. According to results R. indica ‘Major’ and 25, 250, 1000 ppm IBA improved the success of  stenting technique.
