Different Methods of Vegetation
Different types of vegetation
Besides natural methods of vegetative propagation, artificial modes of propagation are also being used. Farmers, gardeners and horticulturists have adopted several such methods like grafting, layering, cutting and tissue culture for propagating plants in gardens and nurseries.
1. Grafting:
In horticultural practices this method is commonly used. In this method the cutting of a plant (scion) is attached to the stem of another rooted plant (stock). After some time the attached cutting becomes an integrated part of the rooted plant. The scion and stock are placed in such a way that no gap remains between them. After some time the attached cutting becomes an integrated part of the rooted plant. The scion and stock are placed in such a way that no gap remains between them Because of the arrangement of their vascular bundles, grafting experiments are successful only in divots and not in monocots. This method is commonly applied to improve the variety of fruits like mango. Wax is used to cover the place where grafting is being done. This is to avoid infection.
3. Cutting:
In rose, sugar-cane, Coleus, Bougainvillea, etc., this method is used to produce new plants. In this process stem cuttings with some nodes and internodes are placed in moist soil which gives rise to adventitious roots and a new plant subsequently. It is a very common method of vegetative propagation. Farmers divide up the rhizomes, tubers or roots stocks at the end of flowering or growing season. Each part grows into a separate plant in the following year. Some plants like dahlia are propagated by root cuttings.
4. Layering:
In some plants one or more branches are bent close to the ground and covered with moist soil. After some time, the underground portion of those branches produce new roots and develop into a separate plant as in jasmine, Rhododendron, Magnolia, etc. The stem or branch that develops adventitious roots while still attached to the parent plant is
