Characterisation of phosphorus uptake by perennial ryegrass(Lolium perenneL.) during regrowth

Abstract: The leaf regrowth stage of perennial ryegrass (Lolium perenne L.) is an effective and generic measure to determine the optimum time for defoliation and reflects important physiological processes. Previous research suggests that uptake of phosphorus (P) fertiliser by perennial ryegrass during regrowth may vary with leaf development stage, however little research has been undertaken in this area. The current study aimed to characterise P uptake with sequential leaf development, in order to provide knowledge whic… Show more

“…Accordingly, it is most likely that P remobilization was more critical to sugarcane regrowth immediately after shoot harvesting, when internal P reserves have a pronounced influence on new biomass production (Kim et al , 2003). For instance, P uptake was found to be low just after defoliation, but an increasing amount of P was removed from the soil during the regrowth of ryegrass (Burkitt et al , 2009). In addition, as sugar remobilization and translocation from roots is affected by P nutrition (Berg et al , 2009), it could be argued that the compromised shoot regrowth of the P-inefficient varieties was also associated with impaired utilization of root sugar reserves under low P availability.…”

“…Indirectly, conclusions about it can be drawn based on the biomass, since the P accumulation throughout the growing period had a positive correlation with the above-ground biomass accumulation. Brink et al [75] also indicates a strong correlation between P uptake and the dry matter of Lolium multiflorum, while Burkitt et al [76] explain such a relationship for Lolium perenne. Italian rye-grass is sensitive to water scarcity and primarily responds with poor tillering [77], which can result in lower biomass.…”
