Fig. 1From: Ethylene enhances root water transport and aquaporin expression in trembling aspen (Populus tremuloides) exposed to root hypoxiaNet photosynthesis (Pn, a), stomatal conductance (gs, b) and transpiration rates (Tr, c) in well-aerated trembling aspen (P. tremuloides) plants (A), well-aerated plants treated with ethylene (AE), plants exposed to hypoxia (H) and subjected to hypoxia and ethylene treatment (HE) for one week. Means ± SE (n = 6) are shown. Different letters indicate significant difference (P ≤ 0.05)Back to article page
