DENDROLOGY

Detailed explanation-1: -Stem. Runners grow horizontally above the ground. Roots. New plants emerge out of swollen, modified roots known as tubers. Leaves. Leaves of a few plants get detached from the parent plant and develop into new plants. Bulbs. Cutting. Grafting. Layering. Tissue Culture.

Detailed explanation-2: -Vegetative Propagation by Roots In this process, new plants grow out of the modified roots called tubers. In fact, in some plant species, roots develop adventitious buds. These buds grow and form new plants/sprouts under the right conditions. For example, Sweet potato and Dahlia.

Detailed explanation-3: -Plant structures allowing natural vegetative propagation include bulbs, rhizomes, stolons and tubers.

Detailed explanation-4: -Vegetative propagation methods include: • rooting of cuttings, • layering or marcotting, • grafting, • micropropagation. Propagation is the natural mechanism by which plants regenerate. Propagation by seeds is the main method by which plants reproduce in nature.
