Question

Distinguish mound layering and air layering.

Answer 1

• Mound Layering:
  In mound layering, a lower flexible branch with leaves is bent to the ground and a part of the stem is buried in the soil and the tip of the branch is exposed above the soil. After the roots emerge from the buried stem, a cut is made in the parent plant so that the buried plant grows into a new plant.

• Air Layering:
  In air layering, the stem is girdled at the nodal part and hormones are applied and covered with moist soil using a polythene sheet. Roots emerge in these branches after 2-4 months. Such branches are removed from the parent plant and grown separately.
