Characteristics of 13 unidentified lipids species that strongly discriminated leaf groups of Vitis vinifera L. ‘Malvasia Fina’ affected by ESCA. White color = p > 0.10 for unaffected levels; dark green = p ≤ 0.05 for decreased levels, light green = p ≤ 0.10 for decreased levels; red = p ≤ 0.05 for increased levels; and rose = p ≤ 0.10 for increased levels (Welch’s two-sample t-test).

CTL = healthy leaves from healthy unaffected control vines, ASY = healthy leaves from foliar-asymptomatic and wood-symptomatic vines, SY1 = chlorotic leaves from foliar-symptomatic and wood-symptomatic vines, SY2 = spotted/scorched leaves from foliar-symptomatic and wood-symptomatic vines.
