摘要

One of the essential factors for plants is the light, particularly that from 400 to 700 nm, this is used for the photosynthesis process, thus, is known as photosynthetically active radiation. However, not all of the light spectrum is used for photosynthesis, but also other wavelengths can induce changes in plant growth and development through their perception and subsequent signaling. Below 400 nm is the UV radiation (100–400 nm), which is classified as UV-A, UV-B and UV-C. This type of radiation is important for plants, as it can induce a variety of responses that can be positive or negative, in dependence of the amount of radiation they receive and the specific wavelength. UV radiation is perceived by specific photoreceptors, and therefore, the plants can respond in a variety of ways, either morphologically, physiologically, biochemically or genetically. Ultimately, plants can respond positively to UV radiation, and enhance growth, development and productivity, but also, tolerance to stress conditions can be induced. Therefore, the use of this type of radiation in plants could be interesting, since it has a variety of potential applications in agriculture. For this reason, a review about UV radiation in plants is presented, with the objective of using it as a tool in agriculture, to improve the growth, productivity, and quality of crop plants, especially when they develop under stress conditions.
