Q.What is artificial method of vegetative propagation? Describe:

Layering is an asexual/vegetative propagation technique where a branch is induced to develop roots while still attached to the parent, before being cut off as a new plant; its two common methods are simple (ground) layering and air layering.

Layering is a method of vegetative propagation in which a stem or branch, while still attached to and nourished by the parent plant, is induced to develop adventitious roots at some point along its length (typically by bending it and covering that portion with soil, or by wounding the bark). Once roots have formed, the rooted portion is severed from the parent plant and grown independently as a new plant genetically identical to the parent.

Two methods of layering:

1. Simple (ground) layering: A low-growing, flexible branch is bent down to the ground; a portion of it is notched or wounded and covered with moist soil, leaving the growing tip exposed above the soil surface. Roots develop at the buried, wounded portion over time; once well-rooted, this portion is cut away from the parent plant and can be grown separately. Example: jasmine, grapevine. …
