Abstract/Contents:"Phosphorus (P) is an important nutrient in turfgrass culture and many soils do not contain sufficient available P to maximize turfgrass growth. Although P is generally required in substantially smaller amounts than either nitrogen (N) or potassium (K), wide ranges in tissue P have been reported in turfgrasses. Variation in P-absorption kinetics of roots among turfgrass genotypes and its inheritance are important in the development of genotypes that are more efficient in P absorption. Therefore in 1990 and 1991, field studies of six cultivars each of Kentucky bluegrass (Poa pratensisL.), perennial ryegrass (Lolium perenneL.), and tall fescue (Festuca arundinacea Schreb.) were conducted comparing clipping production rate, leaf blade P concentration, P-recovery rate in clippings, and visual quality under a moderate P fertilization rate of 37 kg/ha/year. Phosphorus-uptake kinetics of the same cultivars were compared under greenhouse conditions. Significant differences between species and cultivars were observed for both absorption kinetics and field recovery of P. Significant correlations between some P-uptake parameters and field performance were identified. These results indicate that genetic differences in P absorption may exist among turfgrasses at both the interspecific and intraspecific levels and further suggest that studies involving larger numbers of turfgrass cultivars are needed to assess the full range in P-use efficiency."
