The effects of phosphorus (P) deprivation on the changes in the contents of reduced nitrogen (N) and P in the shoots of young maize plants (Zea mays L.) were investigated for up to 30 days after planting (DAP). P deprivation decreased the fresh weight and the contents of Chl, total P, esterified P, acid-soluble P_i, total reduced N, soluble protein N, and insoluble protein N in the en-tire shoot. Thirty DAP, in the fifth leaf blade, which was expanding, P deprivation greatly de-creased the concentration of acid-soluble P_i but had a smaller effect on the concentration of esterified P and little or no effect on the concentrations of Chl, total reduced N, soluble protein N, and insoluble protein N. By contrast, in the fully expanded second leaf blade, P deprivation greatly decreased the contents of acid-soluble P_i, esterified P, Chl, total reduced N, soluble protein N, and insoluble protein N at 30 DAP. It is concluded that P deprivation induced the early initiation and accelerated remobilization of N from old leaf blades. Since this phenomenon is a critical feature of leaf senescence, it is suggested that the P status of leaves is involved in the regulation of leaf senescence in maize.
