Abstract

To determine the appropriate concentrations of nutrients and growth regulators for shoot proliferation and root initiation, several rose hybrid tea cultivars were cultured. Cultured shoot tips and lateral buds from different cultivars proliferated multiple shoots on Murashige and Skoog (MS) medium supplemented with 0 to 4 mg/L BA and 0 to 0.05 mg/L NAA. The ability of the explants to proliferate shoots and initiate roots was affected by genotype, the nodal position of explant, the strength of MS basal medium and growth regulators used. The buds nearest the apex exhibited the slowest rate of development. Most cultivars had the highest shoot proliferation when cultured on MS medium with 2 mg/L BA and 0.01 mg/L NAA, but the degree varied by cultivars. Root development was enhanced by lowering the concentration of MS salts.
