| Abstract/Contents: | Presents a study with the following objectives: "1. To quantify each step in nitrate metabolism for ten Kentucky bluegrass (Poa pratensis L.) and five creeping bentgrass (Agrostis palustris Huds.) 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 efficiency by optimizing the activity and location of those steps which are limiting." States that "our research has shown that cultivars of perennial ryegrass and creeping bentgrass allocate more of their photosynthetic resouces to shoot growth than to roots," and "generally, creeping bentgrass cultivars metabolize more NO3- in their roots than do perennial ryegrasses." Also states that "our findings with these two turfgrasses have so far supported our proposed linkage between root centered NO3- metabolism and greater root growth with less shoot production." This three-year study began in 1998. |
