One of the predicted consequences of the depletion of stratospheric ozone is an increase in the amount of ultraviolet light reaching the surface of the earth, in particular UV-B (320-280nm). Although the real effects are as yet unknown, this change in radiation could have profound consequences for plant growth and productivity. The need for information concerning the relationship between plants and UV-B is therefore pressing. This volume brings together authoritative contributions from leading experts in UV-B/plant studies and is unique in considering interactions at various scales, ranging from the level of the cell through to the level of the community. Information concerning ozone depletion and physical aspects of UV-B radiation complements the biological information to provide a thorough and comprehensive review of the present status of knowledge.
