| Abstract/Contents: | "A greenhouse study was conducted to evaluate the partitioning of nitrogen (N) in roots and shoots of four widely utilized warm season turfgrass species ('Celebration' bermudagrass, 'Argentine' bahiagrass, 'Empire' zoysiagrass and 'Floratam' St. Augustinegrass) grown in a greenhouse at Gainesville, Florida. Studies suggest that warm season grass species respond differently to applied N and that N partitioning varies among species. The objective of this research was to compare N partitioning of four turfgrass species for shoot growth, root growth, and root architectural parameters (root length, and diameter). Rooting parameters (root length and diameter) were analyzed using Win-Rhizo software (Regent Instrument Inc., Canada) and root and shoot tissue was analyzed for total nitrogen content. Based on total root length, root shoot ratio (R/S) and N content in roots, Floratam St. Augustinegrass had greater N partitioning to roots than the other species with a total of ~108 kg N ha-1 in 2011 and ~94 kg N ha-1 in 2012. In comparison to other species, Floratam St. Augustinegrass demonstrated potential for improved N retention in roots, thus Floratam St. Augustinegrass might be able to absorb more nutrients that could enhance its persistence in unfertile soils. Rooting characteristics and N partitioning mechanisms are important to avoid nutrient stress and selection for these characteristics may improve breeding efforts for more N efficient cultivars." |
