Answer» Cutting GRAFTING LAYERING Natural Methods of Vegetative Propagation1. From RootTuberous roots of sweet potato and asparagus become swollen due to storage of food. This forms the new plants in the next season.Vegetative Propagation2. From StemUnderground and subaerial stems are modified for vegetative propagation. ExamplesTuber of potato is an underground stem which stores food. It has buds in the depression called eye which can give rise to a new plant.Vegetative PropagationRhizome is an underground stem that bears buds. Ex ginger, turmeric.Vegetative PropagationBulb is a small disk-like stem surrounded by scale leaves.It is found in onion. In this, a new plant can arise from the stem.Vegetative PropagationAn aerial stem of grass mint and strawberry may give rise to new plant by vegetative propagation.Vegetative Propagation3. By leavesleaves of bryophyllum bear adventitious buds in the Notches in the margin of the leaf. When leaf follows the ground beef buds grow to form the independent plant.Artificial Methods of Vegetative Propagation1. CuttingIn this method, the healthy branch having leaf Buds is planted in the moist soil. The cutting develops roots and grows into a new plant. Example Rose, bougainvillaea, sugarcaneVegetative Propagation2. Layering In this process lower branch of the plant is bent towards the ground and covered with moist soil. The tip of the branch comes out of the soil. After some days the roots are developed. The branch is cut and allowed to grow at a new place. Example JasmineVegetative Propagation3. GraftingThis is a common method used to develop new varieties. In this method, a branch of desired variety of a plant called scion is grafted with a plant of the same type having a well-developed root system (stock).After some days the tissues of the stock and scion join to form a new plant.
