The dataset included analytical values from all volatile components
measured. Principal component analysis (PCA) in Unscrambler
9.7 from Camo (Woodbridge, NJ) was used to evaluate the
data set. Analysis of variance was employed to identify those volatiles
that would be most differentiating between major citrus species.
ANOVA was performed using Statistica 5 from StatSoft (Tulsa,
OK). Means were separated using Tukey’s HSD test at a = 0.05.
