Potential of grafting in vegetable crops: A review

Abstract

Grafting is a method of propagation that involves joining two pieces of living plant tissue together to form a single plant. Drought, excessive temperatures, salinity, flooding, low nutrients and heavy metal contamination, as well as biotic factors including soil-borne pests and diseases, are all limiting vegetable production around the world. Cropping patterns, environmental policies, and the negative effects of climate change have all exacerbated the situation. While genetic breeding can sometimes provide effective solutions to the aforementioned issues, it cannot always do so. Grafting is now seen as a quick alternative to the very slow breeding process. Because of their potential to give tolerance to biotic and abiotic challenges, the production and cultivation of grafted Solanaceous and Cucurbitaceous plants is on the rise all over the world. To reduce post grafting losses owing to incompatibility, the right rootstock and scion cultivars, as well as grafting processes, must be carefully chosen. The methods, physiological basis, and importance of vegetable grafting in biotic and abiotic stress tolerance, improved plant vigour promotion, yield increase, and enhancing quality features are discussed in this paper.
