Question

Name three common methods which are used for the artificial propagation of plants.

Answer 1

To solve this question we have to know about artificial propagation. We know that cutting plant stems and placing them in compost is also a form of artificial reproduction. The process of growing many plants from one plant by man-made methods is called artificial propagation of plants. Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants.

Complete answer:
We know that artificial reproduction or propagation is the creation of new life other than the natural means available to an organism. The three common methods for the artificial propagation of plants are- i) Cutting
ii) Layering
iii) Grafting.

Propagation by stem cuttings is the most regularly utilized strategy to propagate numerous woody ornamental plants. Stem cuttings of numerous most loved shrubs are very simple to root. Normally, stem cuttings of tree species are harder to root. In any case, cuttings from trees, for example, crape myrtles, a few elms, and birches can be roots.

Layering is a method to engender organic fruit-bearing and flower plants, like apple, maple, cherry, and orange trees, to make smaller clones of the parent. Select one of the more new branches on the tree and remove a ring of bark. Wrap wet sphagnum greenery and plastic wrap around the presented wood to secure dampness and help the roots structure.

Grafting includes any cycle whereby a section (called the scion) taken from one plant, is made to unite with and develop upon another plant or some portion of a plant (called the stock). The scion might be a single bud, a little twig bearing a couple to a few buds, a piece of stem (as a cactus), a terminal shoot (as of an evergreen), or a part of roots of a desirable variety.

Note: We know that, in cutting, a particular stem is cut taking care of its nodes. The part that is cut is treated with auxins and lowered into the soil. This results in the formation of a new plant. A plant variety that develops inadequately creates attractive items, for example, palatable natural products can be united onto the stem of a plant that develops well and has attributes like illness or obstruction.
