Abstract/Contents:"Creeping bentgrass (Agrostis stoloniferia) experiences quality decline during summer in the United States transition zone and other regions with similar climate. Various bioproducts have been used to improve creeping bentgrass performance to mitigate effects of summer stress. The yeast cell wall mainly consists of polysaccharides such as polymers of glucose (╬▓-glucan) and polymers of mannose (mannoproteins), which is known to act as microbe- or pathogen-associated molecular patterns (MAMPs or PAMPs) and subsequently induce plant defense responses. This growth chamber study was designed to investigate the effect of decomposed yeast cell wall-based bio-stimulant made from a by-product of beer brewing on physiological fitness and quality of creeping bentgrass under heat and drought stress conditions. The biostimulant "CW1+Fe+Mn" was applied at 1 mL m-2 weekly for 10 applications, and untreated grass served as the control. The treated grass was subjected to heat stress (35/25 ┬░C, day/night) and drought stress via deficit irrigation beginning 10 days after initial biostimulant application. Foliar application for CW1+Fe+Mn at 1 mL m-2 weekly improved turf quality, photochemical efficiency, superoxide dismutase activity, proline content when compared to the control. In addition, the CW1+Fe+Mn treatment also increased root length, surface area, root volume, and biomass relative to the control. The results of this study suggest that foliar application of the decomposed yeast cell wall-based biostimulant could improve physiological adaptation, root growth and turf quality of creeping bentgrass under summer stress environments."
