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 by triggering the production of defensive compounds. Additionally, it promotes root growth and improves stress tolerance in plants, making them more resilient to environmental challenges such as drought and salinity. In horticulture, it is applied to improve fruit ripening and flowering, leading to better crop yields and quality. Its ability to modulate plant signaling pathways also makes it valuable in research for studying plant physiology and stress responses.
