Abstract:
Damask Rose (Rosa damascene Mill.) is one of the most important aromatic roses that used in perfume, essence and medicinal products. This study was conducted to survey the effects of the plant growth regulators on proliferation and rooting capability of Damask rose. The collected samples were disinfected using 10% concentrations of sodium hypochlorite for 15 minute and 70% Alcohol. The treatments which used in this study were two kinds of cytokinin hormones (BA and BAP) in three concentrations (0, 0.5 and 1) for establishment stage and four concentrations of same hormones (0, 1, 2 and 3) for Proliferation stage and auxin hormone IBA in three concentrations (0, 0.5 and 1) for rooting stage. All of the samples were cultured in modified MS media with three replications, in a way that every replication included 3 explants that were based on randomized complete design (CRD). Results of data analysis showed that the highest establishment percentage was 88/89 percent which obtained at 0.5 mg/li BA and the lowest establishment percentage was 20 percent which obtained at 0.0 mg/li BAP. The mean comparison showed that the highest proliferation (3.83) and length of branch (5.34 cm) were achieved at 3 mg (BA), and the lowest proliferation percentage and length of branch were seen, respectively (1.96) at non hormone treatments. The highest rooting percentage was 85% that obtained in 1/2 MS medium containing 0.5 mg/li (IBA) and the lowest rooting percentage (%36) was seen at non hormone treatment.
