Effects of enhanced UV-B radiations on crops
Emmanuelle Bournay, UNEP/GRID-Arendal
Experiments on food crops have shown lower yields for several key crops such as rice, soy beans and sorghum. The plants minimize their exposure to UV by limiting the surface area of foliage, which in turn impairs growth. However the observed drop in yield does not seem serious enough for scientists to sound the alarm.
