Fig. 7

Total glutathione concentration (GSH + GSSG) and ratio of oxidised to total glutathione (GSSG%) in the roots 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. GSH + GSSG: Effects of sampling day, species and treatment as well as their interaction (day by species) were statistically significant (p < 0.05). GSSG%: Effect of sampling day was statistically significant (p < 0.001)
