Leaf initial rubisco activity (A), PI_abs (B) and Chl content (C) in relation to CO₂ assimilation in tea leaves. All the values were expressed relative to the sample treated with 6000 μM N set as 1. Regression equations: A y = 1.07 + ln^x (r² = 0.9317); B y = 1.54x − 0.65 (r² = 0.9329); C y = 1.6x − 0.63 (r² = 0.9932)
