Fig 4. Evolution of stomatal conductance and leaf transpiration in asymptomatic and symptomatic Cabernet Sauvignon grapevines.

Fig 4

(A) Average stomatal conductance in asymptomatic and symptomatic grapevines. (B) Average foliar transpiration in asymptomatic and symptomatic grapevines. The first Esca-foliar symptoms were observed on July 13th (stage 76 on the BBCH scale). Error bars represent SE and a different number of stars for a given date indicates a significant difference between asymptomatic and symptomatic grapevines at p<0.05.
