| Abstract/Contents: | "Cytokinins and ethylene are two major plant hormones that mediate signaling events involved in plant senescence, and a positive correlation between ethylene and leaf senescence in creeping bentgrass. In this study, we hypothesized that exogenous application of cytokinin and an ethylene inhibitor may partially compensate for the change of cytokinin and ethylene during heat stress, resulting in delayed leaf senescence. Creeping bentgrass (Agrostis stolonifera) cv. Penncross was exposed to either heat stress (35°C) or control temperature (20°C) for 35 days in growth chambers. Chemical treatments applied on plants in each chamber included cytokinin [50 ml of 25 μM trans-zeatin riboside (tZR)], ethylene inhibitor [30 ml of 25 μM aminoethoxyvinylglycine (AVG)] and non-treated control (50 ml of distilled water0. Turf quality and chlorophyll content were measured at weekly intervals to indicate heat-induced leaf senescence. Antioxidant enzyme activities and lipid peroxidation levels were also examined to determine whether the differences in leaf senescence and heat tolerance resulting from the applications were related to changes in antioxidant defence mechanisms." |
