Is pollen morphology of Salix polaris affected by enhanced UV-B irradiation? Results from a field experiment in high arctic tundra.
This study tested the hypothesis that the thickness of the pollen wall will increase in response to enhanced UV-B irradiation, by examining the effect of enhanced UV-B irradiance on the pollen morphology of Salix polaris Wahlem. grown in a field experiment on the Arctic tundra of Svalbard.
