Furthermore, individual amino acid contents in grapes are related to the final aromatic composition of wines.
Hyphenated chromatographic/spectroscopic techniques such as LC NMR/MS were also used for the analysis of the aromatic composition of wine phenolic extracts, with their combination being able to provide more information on the aromatic profile of the wines than standalone methodologies [40].
To investigate whether nest aromatic composition is repeatable across years, we tested whether similarity in nest composition was higher within than among individual females.
Sun exposure strongly influences the aromatic composition of grapes.
Control of the main phenological events, berry size and aromatic composition are target traits for viticulturists and wine makers.
In warm environmental conditions, heat and sunlight stress can reduce the aromatic content of grapes, as confirmed in Sicily by Costanza et al. [[ 25], who showed there was negative effect of early cluster zone defoliation on the flavour compounds of the Grillo cultivar and on glycosylated aromatic composition.
Nutrients (NH4-N and PO4-P) supplementation applied upstream of one of the two-stage biofiltration trains (called engineered biofiltration) stimulated the growth of microorganisms, and showed a modest effect on promoting the biological removal of small non-aromatic compositions in NOM.
In addition, for a given territory, the aromatic plant composition of nests varied according to female identity, which indicates that the nest aromatic plant composition results from individual preferences.
The weak observed relation between changes in territory and changes in plant species composition of nests confirms that plant availability in the territory is only a marginal determinant of nest aromatic plant composition.
Aromatic plant composition was indeed significantly more similar within than among females (Anosim, N = 14, P = 0.002) and was not more similar within than across breeding stages (egg laying, incubation, chick rearing) (Anosim, N = 14, P = 0.31) (Table 1).
The similarity in aromatic plant composition between two breeding attempts in the same nestbox was significantly higher when both attempts were made by the same female than when female identity differed (t-test, d.f. = 33, P = 0.02) (Figure 2) (Table 2).
