Sensitivity of Rice to Ultraviolet-B Radiation [PDF]

open access: yesAnnals of Botany, 2006
Depletion of the stratospheric ozone layer leads to an increase in ultraviolet-B (UVB: 280-320 nm) radiation reaching the earth's surface, and the enhanced solar UVB radiation predicted by atmospheric models will result in reduction of growth and yield of crops in the future.
