Ultraviolet radiation (UV; 100–400 nm) is an important spectrum of solar radiation, with UV-A (315–400 nm) accounting for approximately 95% of all UV arriving at the Earth's surface. Currently, only a few reviews have been published on the effects of UV-A on plant growth and physiology, and these reviews indicate that knowledge of UV-A photobiology is limited.
This is partially because previous insights into UV-A effects on plants were obtained from measurements conducted in the field. In this thesis, UV-A wavelength, UV-A dose, and species were studied in a well-controlled environment, and the main findings were that UV-A radiation triggers wavelength-dependent photosynthetic performance and photoprotective acclimation as well as photoinhibition, with the net result that plant growth was barely affected by UV-A exposure.
This thesis filled some knowledge gaps around the effects of UV-A on plants, by using novel LEDs.
