Which of the following options correctly identifies artificial and natural methods of vegetative propagation respectively?
Which of the following options correctly identifies artificial and natural methods of vegetative propagation respectively?
The correct option is B Layering, bulbils
Vegetative propagation is the formation of new plants from the vegetative parts of the plant (roots, stem, leaves). It can be further divided into natural methods and artificial methods.
In natural methods, the somatic part of the plant detaches from the body of the parent plant and develops into a new individual plant under suitable environmental conditions. Natural methods include roots, modified stems (tubers, bulbs, corms, rhizomes, suckers, runners, stolons, offsets, phylloclades), leaves, bulbils, etc. In artificial vegetative propagation, man-made techniques are employed in which a part of the somatic body of the plant can be made to develop into an independent plant.
The rhizome is a type of underground stem modification of plants that are meant to store food for perennation (it is the ability of the organism to survive from one germinating season to another during favourable conditions). They have distinct nodes and internodes. The nodes bear axillary buds that arise from the stem and can give rise to new plants.
Bulbils are multicellular fleshy buds that take part in vegetative propagation.
Various artificial or horticultural methods of vegetative propagation include cutting, layering, grafting, etc.
Cuttings can be cut pieces of root, stem or leaves based on which this method is further subdivided into root cutting, stem cutting and leaf cutting.
Layering is a type of rooting- cutting technique in which adventitious roots are made to grow on stems while it is still attached to the parent plant.
Grafting is a process in which a stem is cut and tied over the stem of another plant having roots to combine the characteristics of both plants into one.
Tissue culture refers to the culturing of the cells, tissues and organs for the purpose of propagation of plant species.
