Higher Plant Acclimation To Solar Ultraviolet-B Radiation, Ronald Robberecht
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Plant acclimation to natural and intensified solar UV-B irradiance was investigated in three species, Oenothera stricta Ledeb., Rumex obtusifolius L., and R. patientia L. The objectives of this study were to determine: (1) the relationship between plant sensitivity and epidermal UV attenuation, (2) the effect of phenotypic changes in the leaf epidermis, resulting from UV-B exposure, on plant sensitivity to UV radiation, and (3) the plasticity of these changes in the epidermis leading to plant acclimation to UVB radiation.
Epidermal UV transmittance was found to differ in magnitude and spectral distribution among the three species examined in this study. Epidermal …
