Fig. 1: Light response curves of foliar gas exchange under different soil treatments.
From: Foliar methane and nitrous oxide fluxes in Salix bebbiana respond to light and soil factors

Panels (a, b) show foliar CH4 oxidation (nmol·m−2·s−1), (c, d) net photosynthesis (µmol CO2 ·m−2·s−1), (e, f) N2O emission (pmol·m−2·s−1), and (g, h) transpiration (µmol H2O·m−2·s−1) with light intensity under 0, 50, 100, 200, 500, 750, 1000, 1250, 1500, 1750, and 2000 µmol·m-2·s-1. The “control” refers to plants in pots with soil only, without any amendments. Data are shown for leaf surface flux measurements for all treatments.
