Summary:
During this study, a chlorophyll fluorescence technique was used to document rapid, diurnal changes in epidermal UV transmittance (TUV) on three herbaceous plant species that grow naturally in high solar UV environments. This was done in the subalpine area of Mauna Kea, on this island of Hawaii. The objective was to determine if the changes occur in these species and to test whether manipulation of the solar radiation regime could alter these diurnal patterns. Additional field studies were conducted at Logan, Utah, USA, to determine if solar UV was causing diurnal TUV changes and to evaluate the relationship between diurnal changes in TUV and UV-absorbing pigments.
