| Abstract/Contents: | Presents a study with the following objectives: "1. To quantify each step in nitrate metabolism for ten Kentucky bluegrass, nine perennial ryegrass, and five creeping bentgrass genotypes. 2. To determine which of these steps correlates best with nitrogen use efficiency under field conditions. 3. To assess the potential for increasing nitrogen use efficieincy [efficiency] by optimizing the activity and location of those steps which are limiting." Reports that "perennial ryegrass and creeping bentgrass allocate most of their photosynthetic resources to shoot growth and little to root growth," and that "both grasses metabolize most nitrate they absorb from the soil in their shoots." Also, "creeping bentgrass metabolizes more nitrate in its roots and partitions a greater portion of its biomass to root growth than perennial ryegrass." This three-year study began in 1998. |

| USGA Summary Points: | Perennial ryegrass and creeping bentgrass allocate most of their photosynthetic resources to shoot growth and little to root growth. Both grasses metabolize most nitrate they absorb from the soil in their shoots. Creeping bentgrass metabolizes more nitrate in its roots and partitions a greater portion of its biomass to root growth than perennial ryegrass. |
