Fig. 2From: Seedlings of two Acacia species from contrasting habitats show different photoprotective and antioxidative responses to drought and heatwavesStomatal conductance (g s) of two Acacia species (A. aneura and A. melanoxylon) under well-watered (open circle) and drought-stressed (closed circle) treatments. Vertical line, shaded areas, letters and asterisks described as in Fig. 1. Values are means (±SE) of n = 5. Effects on all levels and their interactions were statistically significant (p < 0.001)Back to article page
