Ultraviolet (UV) radiation can have various effects on plant growth. It is part of the electromagnetic spectrum beyond visible light. Plants can benefit from UV radiation through photosynthesis and the production of plant colours. In small amounts, it can help increase plant resistance to stress and promote antioxidant protection. However, excessive exposure can cause damage such as leaf burn and reduced yields. In addition, it can act as a natural defence for plants by repelling aggressive organisms. Therefore, exposing plants to small amounts of UV radiation can have positive effects on their health and growth. However, it is important to control exposure to it in order to avoid negative effects.
