Benefits of using plant growth regulators to enhance fruit production

Abstract

Phytohormones are organic compounds naturally produced by plants that regulate growth and other functions at distant locations from their origin, even in minimal quantities. Examples of these plant growth regulators include auxins, gibberellins, cytokinins, and ethylene. Often, fruit production results in fruits of suboptimal quality. Therefore, applying plant growth regulators to fruit crops can significantly improve both yield and quality. For many cultivated plants, especially fruit-bearing ones, the use of growth regulators has become essential in agricultural practices. They are now applied externally to mitigate excessive fruit drop. Auxins and gibberellins, in particular, are commonly used to decrease fruit drop and enhance fruit quality. Various agents influence the transition of fruits from set to ripening and eventual consumer readiness. This review focuses on how plant growth regulators contribute to improving fruit development and production.
