Distribution of 3-Isobutyl-2-methoxypyrazine across Rachis Components of Vitis vinifera Shiraz and Cabernet Sauvignon

Figure 4

Estimated marginal means for IBMP concentration (ng/kg rachis ± SE) in Shiraz rachis for control ( yellow) and box ( charcoal) treatments at harvest (2022) considering the simple main effect of rootstock (Ramsey and own roots). Bars sharing the same letter within the same plot are not significantly different (linear mixed model, α = 0.05, Bonferroni-adjusted). Note. IBMP concentrations (ng/kg rachis) were calculated by adding the IBMP concentration of the respective components together for every biological replicate while considering component proportion (% w/w) (Figure S2 of the Supplementary Material).
