Figure 3.
Comparison of leaf photosynthetic related parameters in 9,311 and HHZ at 50 DAG. The leaf nitrogen content (LNC; a), leaf width (b) and specific leaf weight (SLW; c) of the newest fully expanded leaves. The photosynthetic light response curves (d) and CO2 response curves (e). Light saturated photosynthetic rate extracted from the photosynthetic light intensity response curves (Asat; f), maximum rate of Rubisco carboxylation (Vcmax; g) and maximum rate of electron transport for RuBP regeneration extracted from the photosynthetic CO2 concentration response curves (Jmax; h). Asat normalized by LNC (i), Vcmax normalized by LNC (j) and Jmax normalized by LNC (Jmax; k). Data presented are mean values with s.d. (n = 5). *, **P < 0.05 and P < 0.01 (Student’s t-test), respectively.
