Jasmonic acid is widely used in agriculture as a plant growth regulator. It plays a crucial role in enhancing plant defense mechanisms against pests and diseases. Farmers apply it to crops to stimulate the production of defensive compounds, improving resistance to insect attacks and pathogens. Additionally, it is used to promote root growth and improve stress tolerance in plants, particularly under adverse conditions like drought or salinity. In horticulture, jasmonic acid is utilized to regulate flowering and fruit ripening, ensuring better crop yields and quality. Its application is also being explored in biotechnological research to develop genetically modified plants with enhanced stress resilience and productivity.
