A phytohormone is an organic compound produced spontaneously in plants that regulates development and other functions at a location far from its source in very small amounts. Auxins, gibberellins, cytokinins, and ethylene, are all examples of plant growth regulators. It is a typical occurrence for fruits to be produced that are of inferior quality. Therefore, it would be beneficial to apply plant growth regulators on fruit crops to increase output and quality. For the majority of cultivated plants, and particularly for fruit plants, the use of growth regulators has become a crucial part of agro-technical procedures. They can currently be used exogenously to reduce severe fruit drops in fruit crops. Auxin and gibberellins are frequently used to reduce fruit drop and enhance fruit quality. Several agents are in charge of removing certain fruits from the ontogenic progression from fruit set to fruit ripening and ultimate reach to the customer. In this review, we concentrate on the function of plant growth regulators in the fruit development.
