| Abstract |
Pollen in unopened flowers of most species is totally screened from solar ultraviolet-B radiation by imbricated petals that are largely opaque to UV-B. Following flower opening but before another dehiscence, the anther walls of the species investigated filter out over 98% of the UV-B radiation. Reflectance of UV from corollas of open flowers does not generally appear to add significantly to the solar UV-B radiation environment of pollen. |
