Effect of plant growth regulators on adventitious rooting of Rosa canina L. and Rosa hybrida L.
Plant growth regulators including Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA), 1-Napthalene acetic acid (NAA) and 2,4-dichlorophenoxyacetic (2,4-D) at different concentrations were used to induce adventitious rooting from the stem cuttings of Dog rose (Rosa cani...
