Efficacy of Different Concentrations of NAA on Selected Ornamental Woody Shrubs Cuttings

Ornamental woody shrubs are used in landscape design worldwide. Their propagation can be made generatively and vegetatively. Vegetative propagation methods are mostly used by nurseries, as such methods are quick and the newly propagated plants inherit the genetics of the mother plant. However, rooti...
