Effect of hormones, light and media treatments on rooting of Juniperus oblonga cuttings

Due to several problems in natural regeneration of Juniperus oblonga, asexual reproduction has important implication in restoring the habitat of this species. The aim of this study was to investigate the effects of different treatments including hormones, bed composition and light on rooting of Juniperus oblonga cuttings. Cuttings were taken from young stands and treated with 2500, 5000 and 7500 ppm of IBA and then planted in two different beds (fine and harsh bed) under white and red light as split plots. Data was analyzed using SAS software package and tested by Duncan method. Results indicated that bed composition and light treatments were significant (p-value <0.01) and hormones treatments were very significant (p-value < 0.05) in rooting of J. oblonga cuttings. The average of rooting in combination of white light, fine bed composition and IBA treatments (0-5000 ppm) at 28% was remarkable and can be used in mass production of J. oblonga seedling in rehabilitation programs
