Figure 3

Metabolic responses to progressive water deficit in leaves of Cabernet Sauvignon and Shiraz. Values are the logarithmic transformed fold change (water deficit/irrigated) of selected leaf metabolites on days 18, 26, and 34 of the experiment. Bolded figures represent significant difference between irrigated and water deficit treatments as tested by the Student’s t-test (p-value < 0.05). Different colors represent the increase (green) or decrease (red) in metabolite logarithmic fold change as indicated in the color index (n = 6).
