what is artificial vegetative propagation? explain in brief the different methods of it.

can u plz explain cutting nd layering??

 okk!!

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

2. Bud grafting

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 called a layer. In many plants, layering can also be induced artificially.

5. Tissue Culture

thnkzz a lottt....

welcome!!
