Uses of biological spectral weighting functions and the need of scaling for the ozone reduction probe: calculating the increase of biologically effective solar ultraviolet-B radiation (UV-B.) due to ozone reduction, assessing current latitudinal gradients of UV-B., and comparing solar UV-B. with that from lamps and filters in plant experiments. Plant UV action spectra (usually determined with mono

Beneficial effects of enhanced UV-B radiation under field conditions: improvement of needle water re al. 1995) were investigated with seedlings of .. Plants received ambient or ambient plus supplemental UV-B radiation (biologically equivalent to a 15% ozone depletion over Patras, 38.3° N, 29.1° E) and natural precipitation or additional irrigation. Treatments started on 1 February, 1994 and lasted

Morphological and physiological responses of bean plants to supplemental UV radiation in a Mediterraat may occur because of stratospheric ozone depletion; most of them were performed in controlled environment conditions where plants were exposed to low photosynthetically active radiation (PAR) levels and high UV-B irradiance. Since environmental radiative regimes can play a role in the response of

Leaf thickness and UV-B absorbing pigments of plants in relation to an elevational gradient along thed UV-B are increasing leaf thickness and increasing concentrations of UV-B absorbing compounds. In some (UV-B resistant) plant species increased leaf thickness and UV-B absorbance may form part of mechanisms protecting plants from UV-B damage. However, in UV-B sensitive plant species leaf thickness
