It also includes the sectioning of stems to include active leaves, tip or leaf/ eye cuttings, or dormant apical or axillary buds known as dormant cuttings. Vegetative propagation encompasses a range of techniques: softwood (leafy) stem cuttings, hardwood (leafless) stem cuttings, leaf cuttings, root cuttings, micropropagation of meristematic or other regenerative tissues, layering, stooling, grafting (budding), and propagation by … The adventitious buds are borne on such structures.
