Fig. 3From: Gas exchange, biomass and non-structural carbohydrates dynamics in vines under combined drought and biotic stressPhotosynthetic rate (A) measured in 5C (a) and Riesling grafted on 5C (b) during treatments application (n = 4–7). W = well-watered plants; D = drought-stressed; C = control, non-phylloxerated; P = root phylloxerated. Letters denote statistically significant differences within Irrigation (Factor I; W and D), while n.s. indicates the lack of differences. A significant interaction between factors (Irr x Inf) was observed in 5C on 15th and 22nd day after stress imposition, i.e. within C level: W > D; within P level: W > D. No statistically significant differences within factor Infestation were observedBack to article page
