Vegetative Propagation In Flowering Plants – It is process of asexual reproduction, which involves the vegetative parts of a flowering plants such as stem, leaves etc.
Following are different types of vegetative propagation in flowering plants.
(a) By stem (b) by leaves
(a) By stem
Common methods of vegetative propagation by stem are by runners and suckers.
Runners: some stems from which new offspring can be produced are runners. A runner is a long, thin, stem which is spread along the surface of soil. It gives adventitious roots at nodes, which grow into the soil. The nodes may separate giving rise to new plants. Examples are grasses, strawberry etc.
(Fig 16.4) Runner and sucker
Suckers: these 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. Examples are mint (podina) and banana. (Fig. 16.5)
(b) By leaf
In some plants like bryophyllum, vegetative propagation is by leaf. The leaves of this plant have notches on their margins with adventitious buds. When a leaf falls on the ground the adventitious buds grow in to new plants.
