A.
layering
Layering is a means of plant propagation. In layering middle part of a soft basal branch is defoliated, slightly injured and pegged in the soil to develop adventitious roots. Later on, the branch of layer is separated and planted. It has evolved as a common means of vegetative propagation of numerous species in natural environments.
