Answers
i) Cutting:
Cutting is a portion of stem, usually, with some buds. The stem cutting is placed vertically in the moist soil.
After sometime, the cutting gives rise roots and the cutting grows into a new plant. The cutting method of propagation is commonly used to grow rose, bougainvillea, sugarcane, pine-apple plants.
(ii) Layering:
In this method a branch of the plant that is bent towards ground. The bent portion of the branch is covered with the moist soil.
Sometimes pegs are used to keep the branch in the soil. The portion of the branch to be kept in the soil is injured by giving oblique cuts (tonguing) V-shaped cuts (notching) by removing rings of bark (ringing).
Many plants like raspberry, strawberry produce natural layers which can be separated from parent plant. After sometime, the adventitious roots develop from the branch.
