Fig. 2

Photosynthetic light–response (a) and CO2–response curves (b) in the leaves of hot pepper plants under different levels of irrigation water salinity (ECiw) and leaching fractions (LF) (the measurements were made at a CO2 concentration of 400 μmol mol−1 and at a PPFD of 1200 μmol mol− 1, respectively for light–response curves and CO2–response curves). The three regression curves are made for the leaves of ECiw of 0.9, 4.7 and 7 dS m− 1, respectively, across the two LFs
