Question

Air layering is performed in the case of
A. Jasmine
B. Grapevine
C. Gooseberry
D. Litchi

Answer 1

Layering is a method of vegetative propagation in plants. It involves induction of root formation while the branch is attached to the mother plant. Since, the daughter plant is attached to the mother plant in the initial stages of propagation, the transfer of water and nutrients is easily done and thus the success of the process is very high. Layering can be of two types – ground layering and air layering.

Complete step by step answer: Air layering is also known as marcotting. In this process, the stem is cut and a strip of the bark is removed. On this a layer of moss or soil is wound and covered with a plastic. The moss layer helps to retain moisture and the plastic inhibits too much moisture accumulation on the region. Often, root inducing hormones are applied. When sufficient growth in roots takes place, the plant is planted in the soil. The name air layering is derived from the fact that the process takes place in branches suspended above the ground – in the air. Litchi is propagated by air layering.
Jasmine, Grapevine and Gooseberry are all propagated by simple layering or ground layering. In this process, a branch of high vigor is chosen, bent and buried into the ground. The ground should be kept moist. Once the roots emerge and grow, the stem is cut and planted at a distance from the mother plant.
Therefore, the correct option is (d).

Note: Air layering is a technique of vegetative propagation of plants. The stems are cut and strips are removed from the bark and wound by moss and plastic. Once roots develop from the stem, the daughter plants are cut and planted separately. layering is a common method of asexual propagation used by horticulturists to produce desirable plants. The process of layering has a high rate of success.
