| Abstract/Contents: | "Nitrate uptake and reduction, as well as biomass partitioning, was compared among nine cultivars each of perennial ryegrass and creeping bentgrass as these factors might contribute to preventing summer decline in cool-season turfgrasses. Nitrate uptake rates for solution-grown perennial ryegrass cultivars averaged 2.5 times greater than those for creeping bentgrass. Turf cultures of creeping bentgrasss partitioned more than twice as much of their total biomass to roots as did perennial ryegrass cultures. Root specific nitrate reductase activity (NRA) was similar for both turfgrass species, but shoot-specific NRA in perennial ryegrass was more that twice that of creeping bentgrass. These findings demonstrated that creeping bentgrass metabolized 13.5% of the nitrate it absorbed within its roots while perennial ryegrass metabolized only 4% of its nitrate within its roots. If partitioning more total biomass and nitrate metabolism to its roots makes a turfgrass more tolerant of summer conditions, creeping bentgrass should experience less summer decline than perennial ryegrass. |
