| Abstract/Contents: | "Increasing the capacity of low maintenance turf to recover nitrate efficiently from the soil has become an important research objective for economic and environmental reasons. Understanding cultivar variation among turfgrass species in their capacity for nitrate absorption is essential to achieving this goal. We measured the kinetic parameters of nitrate absorption (Vmax, Km and Cm) for six cultivars each of Kentucky bluegrass (Poa pratensis L.), perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea Schreb.). Grass cultures were grown in a greenhouse and nitrate uptake kinetics were measured via a solution depletion technique. Root affinity for nitrate and capacity for nitrate uptake varied significantly among cultivars of the three turfgrass species. Variation among cultivars exceeded that among means of the three species. Field plots of the same grasses were used to measure rates of clipping production and nitrogen delivery to leaves. These measures of leaf growth and nitrogen transport to leaves did not correlate well with parameters describing nitrate absorption by roots. Reasons for these poor correlations are discussed as are the opportunities for evaluating the nutrient uptake efficiency of turfgrass genotypes based on kinetic analyses of nutrient absorption." |
