Photosynthetic rate (Pn) of leaves of plants grown with normal or low phosphorus. Seedlings (after germination) were treated with 1.0 mM phosphorus (CK), 0.2 mM phosphorus and 0.02 mM phosphorus (LP) for 15 days under sand-culture system. The photosynthetic rate was measured by the CIRAS-3. Values are means ± SD. n = 6 for each genotype. Asterisks indicate significant differences compared with WT plants (Student’s t-test). ∗P < 0.05; ∗∗P < 0.01.
