Abstract

Plant extracts have emerged as promising biostimulants in agriculture, offering natural and sustainable alternatives to traditional inputs. Derived from various plant species, these extracts contain bioactive compounds that positively influence seed germination, enhance plant growth, and improve both productivity and nutritional composition. Their application has also shown potential in extending fruit shelf life by suppressing pathogen growth. However, challenges remain in standardizing extraction processes, and significant knowledge gaps exist regarding their optimal application. This review provides an overview of recent findings on the use of plant extracts as biostimulants or edible coatings, focusing on their application methods for vegetables where the edible part is the fruit. It emphasizes the reasons behind observed differences in results among similar studies, highlighting the need for further research to maximize the effectiveness of plant extracts as eco-friendly biostimulants in sustainable agriculture.
