Abstract

The effects of elevated UV-B radiation and water limitation have been evaluated in terms of the biochemical, physiological, morphological and productivity responses of common buckwheat (Fagopyrum esculentum Moench) and tartary buckwheat (Fagopyrum tataricum Gaertn.). Research was carried out under semi-controlled conditions. Common and tartary buckwheat were exposed to UV-B radiation and water limitation in different combinations. Photosynthetic pigments, UV-absorbing compounds, potential and effective photochemical efficiency, stomatal conductance, plant morphology and biomass production were monitored. The negative effect of elevated UV-B radiation on growth parameters in common buckwheat was highly significant in watered plants but less pronounced in plants exposed to water limitation. However, in tartary buckwheat UV-B radiation mitigated the negative effects of water limitation, resulting in increased biomass production.
