Dominic Petrella, Ph.D. is Postdoctoral Associate, Department of Horticultural Science, University of Minnesota. He received his PhD from The Ohio State University in Horticulture and Crop Science. He works in diverse areas of turfgrass physiology that have common goals of selecting and evaluating the regulation of improved traits among fine fescue turfgrasses including allelopathy, nitrification inhibition, rhizome occurrence and development, and tolerance to poor light conditions. His research interests revolve around the physiological acclimation and adaptation of turfgrasses to sub-optimal environmental conditions under low-input management. In particular, he is interested in better understanding the interactions of light and abiotic stresses.
