Plant growth and the absorption of P by Italian ryegrass from nutrient solution was affected by P supply, whereas the distribution and accumulation of P within the ryegrass was largely determined by the kind of, and age of, tissue sampled. Blade 1, the youngest blade that was fully open and had a ligule, and H2PO4-P were selected, from 6 plant parts sampled and 2 forms of P determined, as the best combination to diagnose the P status of Italian ryegrass. About 750 ppm of H2PO4-P in blade 1 tissue was tentatively set as the critical concentration for growth of the ryegrass.
