Abstract
    Uptake dynamics of dissolved inorganic phosphate (DIP) and dissolved inorganic nitrate (DIN) in young Palmaria palmata (n = 49), cultivated in a range of DIP concentrations (0.0–6.0 µmol · L−1) and nonlimiting DIN concentration (50 µmol · L−1) under fully controlled laboratory conditions, were quantified in a ‘pulse‐and‐chase’ approach over 5 weeks. Two different uptake rates were specified: (1) surge uptake (VS) after starvation and (2) maintenance uptake with filled nutrient pools (VMS−2 · d−1 and DIN of 15.6 ± 4.3 µmol · cm−2 · d−1 , as well as VM−2 · d−1 and DIN of 5.6 ± 2.1 µmol · cm−2 · d−1 were calculated. In addition, an absolute size of the internal storage capacity (ISC) for DIP of 22 µmol · cm2 and DIN of 222 µmol · cm2 was determined. A DIP‐to‐DIN uptake ratio of 1:10 under VMSP. palmata and allow for an optimization in cultivation.
