Fig. 4.Relative abundance of the top 20 fungal operational taxonomic units (OTUs) classified by genus in control and symptomatic Vitis vinifera cv. Sauvignon blanc trunk samples (healthy wood) from the three nitrogen levels. Each bar represents one sample. Note the absence of samples from symptomatic plants in the [NH4NO3]low level, as only two plants were symptomatic (not included).

✍️ Dell’Acqua et al.

A deficit in nitrogen nutrition reduced esca leaf symptom expression in mature grapevines, probably through lower transpiration and higher secondary metabolism.

Fig. 3.Mean leaf chlorophyll concentration and fluorescence values. (A) Mean leaf chlorophyll concentration in µmol m–2 of leaf tissue. Data represent averages for the two sampling dates [6 and 8 months post-inoculation: 12 August (12-Aug) and 2 September (2-Sep)] per cultivar and treatment. Bar graphs for the first sampling date represent averages of inoculated (INOC) (n=22–25) and non-inoculated wounded control plants (NIW) (n=5). The second sampling date represents averages of INOC (n=5) and NIW plants (n=5). Chlorophyll content significantly differed between Cultivar and Treatment. (B) Fluorescence values (Fv/Fm) taken on the same sampling date. There were significant interaction effects of Cultivar and Treatment on Fv/Fm. SY stands for Syrah and -INOC refers to the inoculated treatment group. ZN stands for Zinfandel and -INOC refers to the inoculated treatment group. The mock-inoculated control group is labeled NIW.
