Extended Data Fig. 5: Relationships of net photosynthesis and leaf conductance to soil water content for different VPG classes and leaf temperatures.
From: Effects of climate warming on photosynthesis in boreal tree species depend on soil moisture

Relationships are shown for two temperature treatments, for three VPG classes (left four panels) and three leaf temperature classes (right four panels). Data are pooled across all species and show the regression line for Anet and gs in relation to VWC in three VPG classes (0.4–1.6, 1.6–2.8, 2.8–4.0 kPa; red, green and blue lines, respectively) and for ambient and warmed (+3.4 °C) treatment plants; and in relation to VWC in three Tleaf classes (8–20, 20–32, 32–38 °C; dashed, dotted, and solid black lines, respectively) for ambient and warmed (+3.4 °C) treatment plants. Sample sizes in each panel, around 950–995. A few data points are out of the y-axis range and therefore not visible.
