Table 2. Photosynthesis rates, photosynthetic phosphorus-use
efficiency (PPUE), photosynthetic nitrogen-use efficiency (PNUE), foliar
mass per area (LMA) and the foliar ratio of nucleic acid phosphorus (P)
to organic P of Banksia attenuata and B. sessilis grown in
three substrates. Values are means ± SE (n = 10); asterisks show
significant differences between the two species by t test.ns not significant, * P< 0.05, ** P < 0.01,*** P < 0.001. Different letters
represent significant differences for the two species among the
substrates (P < 0.05). SLAT: sand plus laterite, SLIM:
sand plus limestone.
