Fig. 6From: Towards a scientific interpretation of the terroir concept: plasticity of the grape berry metabolomeoCPLS2-DA models using the volatile metabolites applied within each of the three geographical regions to distinguish the vineyards. For each model, the score scatter plot (a, c, e) and the correlation loading plot (b, d, f) are provided. Samples, corresponding to seven vineyards at three developmental stages are separated regardless of the vintage. Vineyards: ▼ = AM; ● = BA; ◼ = BM; ✦ = CS; ♦ = FA; ★ = MN; ▲ = PM. Yellow: Lake Garda macrozone (a, b); sky blue: Soave macrozone (c, d); fuchsia: Valpolicella macrozone (e, f). Groups of metabolites are shown in different colors. ui = unidentifiedBack to article page
