| Abstract/Contents: | "Heat stress is a major factor contributing to summer bentgrass decline in creeping bentgrass (Agrostis stolonifera L.), a cool-season turfgrass susceptible to premature leaf senescence when exposed to elevated temperatures for prolonged periods. The objective of this study was to determine the physiological effects of small molecules (SMs) that potentially have plant growth-regulator (PGR) properties on creeping bentgrass exposed to heat stress. Plants were maintained in environmentally-controlled growth chambers under non-stress (22/18 °C, day/night) or heat stress (35/30 °C, day/night) temperature conditions for 25 d, and turf quality, electrolyte leakage, and chlorophyll content were measured. Plants were foliar sprayed with several PGR-SMs prior to and during heat stress. At 25 d of heat stress, all treated plants had significantly higher levels of chlorophyll a and b as well as total chlorophyll content in comparison to the untreated controls. Electrolyte leakage was affected differentially by PGR-SMs under heat stress. The current results suggest that the PGR-SMs compounds applied may have had roles in suppressing leaf senescence and improving membrane stability." |
