Figure 2.
The relationship (initial slope) between JO2 and the A in Arabidopsis wild type (WT), TL46, and TL25. The plants were grown under a PPFD of either 100 (•, ▪) or 350 (○, □) μmol m−2 s−1. CO2 assimilation was conducted under various PPFD regimes at 25°C, an O2 partial pressure of 20 kPa, and a CO2 partial pressure of either 31 Pa (○, •) or 80 Pa (□, ▪). Symbols represent means of measurements of two plants.
