Vegetative Propagation in Flowering Plants



In plants, vegetative propagation takes place both naturally and artificially.
Natural vegetative propagation (asexual method) involves the vegetative parts of a flowering plant such as stem, leaves etc.
Natural vegetative propagation takes place by these two methods a) By stem and b) By leaves
BY STEM: common methods of vegetative propagation by stem are runners and suckers.
RUNNERS: A runner is a long and thin stem, which creeps along the surface of the soil. It gives off adventitious roots at nodes, which may separate from the parent plant to give rise to a new plant.
Examples are grasses, strawberry etc.
SUCKERS: Suckers are lateral branches of the stem with terminal buds and grow from the base of underground stems of certain plants. They grow obliquely to the soil level and produce new aerial shoots with adventitious roots, establishing new daughter plant e.g. mind, and banana.
