Abstract

Rosa damascena Mill. as a most important aromatic plants is the best commercial species of the fragrant roses in Iran and many countries. To study callus induction and proliferation in Rosa damascena Mill., axillary buds of five genotypes collected from different parts of Iran was used as explants. These were cultured on MS medium supplemented with growth regulator(s) and solifiled with 0.7% (w/v) agar, at 25±1 °C. Different concentrations of 2,4-D (2, 3 ,4 ,5 ,6 mg/l), IBA (0.1 mg/l), NAA (5 ,10 mg/l), PCPA (3, 5 ,7 ,9 ,10 mg/l) Kinetin (0.1, 1 mg/l) and BAP(1, 2mg/l) were used. Genotypes showed significant differences (P<0.01) for callus induction, Also, highest callus induction was observed in genotypes of Kashan cultured on MS cultured medium contained 1 mg/l Kinetin and 5 mg/l PCPA. The results emphasized on genotype, kind and concentration of growth regulators as key factors in callogenensis and proliferation of Rosa damascena.
