| Abstract/Contents: | "High temperature and drought stress are the primary abiotic stresses limiting the growth of cool-season grass species, such as creeping bentgrass (Agrostis stolonifera). Leaf senescence or chlorosis associated with summer bentgrass decline are symptomatic of heat and drought injury. Plant growth promoting rhizobacteria (PGPR) that produce ACC deaminase can help reduce the impacts of abiotic stress in plants. Four strains of endophytic Burkholderia sp. bacteria were isolated from the roots of native grasses from the New Jersey Pine Barrens and were found to possess ACC deaminase activity. Each individual strain, as well as a mixture of all four strains, were used to inoculate the roots of creeping bentgrass (cv. 'Penncross'). The plants were subjected to optimum conditions, heat stress, or drought stress treatments in growth chamber trials. Physiological parameters of inoculated plants were compared to non-inoculated controls by measuring turf quality (TQ), relative water content (RWC), leaf chlorophyll content (CHL), electrolyte leakage (EL), and photochemical efficiency (Fv/Fm) as indicators of leaf senescence. At the conclusion of the stress treatments, root morphological parameters (root volume, surface area, and diameter) were analyzed. While the plant response differed among individual PGPR strains, several strains were effective in improving physiological and morphological traits in creeping bentgrass under heat and drought stress conditions. Future studies focused on optimizing the bacteria/host/stress interaction and understanding the mechanisms involved in the bacteria-mediated stress tolerance response will facilitate the adaptation of PGPR inoculants for field application." |
