Fig. 3. — Relationship between leaf nitrogen concentration (LNC) and leaf photosynthetic parameters. The correlation study was performed for high-nitrogen (HN) treatment (n=17) and low-nitrogen (LN) treatment (n=21). The leaf photosynthetic parameters used include light-saturated photosynthetic rate A_sat (A), maximum apparent quantum yield for CO₂ (Φ_CO2) (B), and curvature factor (θ) of the response of photosynthetic CO₂ uptake to incident photosynthetic photon flux density (A-PPFD) (C). LNC was calculated as LNC=(leaf nitrogen dry weight)/(leaf dry weight)×100%.
