The Interaction Of Ultraviolet-B Radiation Stress And Plant Competition In Agricultural Plant Populations, Warren Glenn Gold
The Interaction Of Ultraviolet-B Radiation Stress And Plant Competition In Agricultural Plant Populations, Warren Glenn Gold
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effect of ultraviolet-B radiation enhancement upon the competitive interactions of two species pairs was studied in the field. Wheat (Triticum aestivum L. 'Bannock') was paired with wild oat (Avena fatua L.) and jointed goatgrass (Aegilops cylindrica Host) to represent competition between species pairs in agricultural situations. Specially modulated ultraviolet lamp systems provided either low ultraviolet-B enhancement (simulation of a 16 % ozone layer reduction based upon the generalized plant action spectrum), high ultraviolet-B enhancement (40 % ozone reduction) or control (ambient solar ultraviolet-B) irradiance.
Ultraviolet-B radiation enhancement significantly altered the competitive interactions of the species pairs. …
