Physiological adjustment in response to stress. (A) Osmolality (π), (B) Carbon/Nitrogen ratio (C:N) and (C) leaf water potential (Ψl) of Cabernet Sauvignon (Cs) and Shiraz (Sh) on day 34 of the experiment. Columns represent means ± SE (n = 6) and different letters represent significant difference between irrigated (IR) and water deficit (D) treatment as tested by the Student’s t-test (p-value < 0.05).
