Propagation of rose species in vitro Academic Article uri icon


  • Several rose species (Rosa rugosa, R. wichuraiana, R. setigera, R. laevigata, R. banksiae, R. roxburghii, R. odorata) and interspecific hybrids were cultured to determine the appropriate concentrations of nutrients and growth regulators for shoot proliferation and root initiation. Cultured shoot tips and lateral buds from different genotypes proliferated multiple shoots on a basal medium [Murashige and Skoog (MS) salts, vitamins, glycine, sucrose, and agar] supplemented with 0 M to 17.8 M (4 mg l-1) 6- benzyladenine (BA) and 0 M to 0.54 M (0.1 mg l-1) naphthalene acetic acid (NAA). The ability of the explants to proliferate shoots and initiate roots was affected by the genotype, the nodal position of the explant, the strength of the MS basal salts, and the growth regulators used. The buds nearest the apex exhibited the slowest rate of development. Most species had the highest shoot proliferation when cultured on basal MS medium supplemented with 8.9 M (2 mg l-1) BA, but the degree varied by species. Root development was enhanced by lowering the concentration of MS salts. With difficult-to-root species, rooting was improved by supplementing the media with 11.4 M (2 mg l-1) indole-3-acetic acid (IAA) or by giving them a 7-d dark treatment at 10 C.
