  author={Peter S Searles and Stephan D Flint and Martyn M. Caldwell},
The potential effects of increased ultraviolet-B radiation (UV-B, 280–320 nm) simulating stratospheric ozone depletion in field studies with vascular plants have previously been summarized only in narrative literature reviews. In this quantitative synthesis, we have assessed the significance of solar UV-B enhancement for ten commonly measured variables involving leaf pigmentation, plant growth and morphology, and photosynthesis using meta-analytic statistical methods. Of 103 papers published… 
Solar ultraviolet radiation and ozone depletion-driven climate change: effects on terrestrial ecosystems.
Advances in knowledge of how UV-B radiation, together with other climate change factors, influence terrestrial organisms and ecosystems are summarized and key uncertainties and knowledge gaps are identified.
The increased ultraviolet-B (UV-B) radiation (280–320 nm) on the Earth’s surface is one of the most important concerns of global change. This concern is primarily because increased UV-B radiation has
Effects of enhanced UV-B radiation on plant physiology and growth on the Tibetan Plateau: a meta-analysis
Local climate conditions may regulate effects of enhanced UV-B radiation on alpine plants, as forests rather than grasslands exhibited a positive response of SOD and a negative response of Pn to enhanced UV -B radiation, which varied with ecosystem types.

Advances in knowledge of stratospheric ozone dynamics and climate change are summarized, and uncertainties and knowledge gaps are identified that limit the ability to fully evaluate the ecological consequences of these environmental changes on terrestrial ecosystems.
Growth and Defense Metabolism of Plants Exposed to Ultraviolet-B Radiation
Increases in ultraviolet (UV) radiation at the Earth’s surface due to the depletion of the stratospheric ozone layer are major concern for researchers, posing interest in the mechanisms of various
Integration and scaling of UV‐B radiation effects on plants: from molecular interactions to whole plant responses
The model showed significant interactions between UV‐B radiation effects and temperature and any factor leading to inhibition of photosynthetic production or plant growth during the midday, but the effects were not cumulative for all factors.
Effect of UV-B Radiation on Leguminous Plants
Sun is the primary source of energy for photosynthetic life on Earth. Ultraviolet-B (UV-B, 315–280 nm) radiation is a natural constituent of solar light reaching Earth’s surface due to the thinning


Stratospheric ozone reduction, solar UV-B radiation and terrestrial ecosystems
Stratospheric ozone reduction is occurring and will continue to increase in magnitude into the next century. Yet, the consequences for terrestrial ecosystems of the increased solar UV-B (280–320 nm)
Ozone depletion and increased UV-B radiation: is there a real threat to photosynthesis?
It is concluded that O 3 depletion and the concurrent rise in UV-B irradiance is not a direct threat to photosynthetic productivity of crops and natural vegetation.
Effects of ultraviolet‐B radiation on the growth and yield of crop plants
This paper reviews growth chamber, greenhouse, and field studies on the effects of ultraviolet-B (UV-B) radiation on agricultural crop plants, finding a considerable degree of variability exists in sensitivity to UV-B radiation between different species.
The effects of ultraviolet-B radiation on loblolly pine
The results suggest that the effects of UV-B radiation may accumulate in trees and that increased UV- B radiation could significantly reduce the growth of loblolly pine over its lifetime, and point to a need for multiple season research in any analysis of potential consequences of global change on the long-term growth of trees.
Morphological responses of crop and weed species of different growth forms to ultraviolet-B radiation
Under glasshouse conditions, UV-B exposure was found to reduce leaf blade and internode lengths and increase leaf and axillary shoot production in several species, suggesting changes in competitive balance more frequently when monocots are involved in mixtures, rather than mixtures of only dicots.
Effects of ozone depletion and increased UV‐B on terrestrial ecosystems
UV‐B effects on interactions between organisms are probably more important than the direct effects of UV‐B on the organisms, with the possible exception of direct effects on perennial plants.
Spectral balance and UV‐B sensitivity of soybean: a field experiment
Soybean [Glycine max (L.) Merr.] cultivar Essex was grown and tested for sensitivity to UV-B radiation (280–320 nm) under different combinations of UV-A (320–400 nm) and PFD (400–700 nm) radiation in
Effects of increased UV-B radiation and elevated levels of tropospheric ozone on physiological processes in European beech (Fagus sylvatica)
As a consequence of the ongoing reduction of the stratospheric ozone layer, the vegetation is exposed to increasing levels of UV-B radiation (280-320 nm). In addition ozone in the troposphere is a
Ultraviolet-B radiation and ozone effects on growth, yield, and photosynthesis of soybean
The projected increase in solar ultraviolet-B (UV-B) radiation due to depletion of stratospheric ozone (O 3 ) has caused concern regarding possible UV-B damage to crops. At the same time,
Changes in growth and pigment concentrations with leaf age in pea under modulated UV-B radiation field treatments
Pea was much less sensitive to enhanced UV-B than in previous growth-chamber and greenhouse studies, and in nearly all casesUV-B treatment effects were overshadowed by leaf-age effects, suggesting researchers may need to consider leaf age in UV- B experimental designs.
