What role does far-red light play when light intensity is high?
By Dominic Petrella
I am continually amazed by the impact that light has on turfgrass growth and development. We know that the quantity (intensity) of light impacts photosynthesis as well as alters overall growth and development, and we know that the quality or composition of light also alters gene expression, growth, and developmental responses in all plants.

Check out our team’s latest efforts in educating the public about our work. Dominic Petrella, Sam Bauer, Brian Horgan, and Eric Watkins wrote Fine fescues for golf course putting greens for Golf Course Management magazine (GCM). Learn more about fine fescues' performance as putting greens under minimal management.
New research publications from our team - 11/12/20
Learn more about our research! Two new research articles from our group have been published in Crop Science. Florence Sessoms and Eric Watkins have published an article on heat stress in cool season turfgrasses, and Dominic Petrella and Eric Watkins have published an article on the differences in shade responses in the fine fescues.
Sunflecks on shaded turfgrass: Good, bad, or of no consequence?
By Dominic Petrella
When we think about turfgrass shaded by trees we as researchers often focus on reductions in light intensity, reductions in the red to far-red ratio (R/FR ratio) along with other changes in spectral quality, competition for water and mineral nutrients, and alterations to temperature compared to full sun environments. However, another challenge for turfgrass plants under shade is exposure to sunflecks.

Turfgrass Science Team at the 2019 ASA-CSSA-SSSA Annual Meeting
The Turfgrass Science team from the University of Minnesota was well-represented at this year’s ASA-CSSA-SSSA Annual Meeting held on November 10-13, 2019 in San Antonio, TX. Seven people gave oral presentations and five people presented posters. Additionally, congratulations go to two members of our group who placed in the graduate student oral presentation contests:
