Abstract:
Grafting is a technique of vegetative propagation in plants where two plant parts, viz., scion and rootstock are joined together through tissue regeneration so as to develop into a single composite plant. The lower portion of the graft that provides the root system of the composite plant is known as the rootstock whereas the upper portion of the graft that develops into the shoot system is known as the scion. The main objective of vegetable grafting is to physically merge positive qualities of both the parts in an individual plant and harness an integrated result. Among the major vegetable crops, grafting is mainly adopted in Solanaceae and Cucurbitaceae family. The major factors that lead to the increased adoption of this technique in vegetables are to achieve resistance against soil borne pathogens, tolerance to abiotic stresses and potential increase in yield of the crops. It also helps to minimize the cost of production of crops and reduces the enormous use of fertilizers and pesticides, thus, maintaining the soil fertility.
