1Average obtained from nine plants ± SEM (ng/h/g fresh plant weight).

2The KI (Kováts index) values were obtained on a non-polar HP-1 GC column.

3P values are from ANOVA (df = 2, α = 0.05) on log-transformed data. Different letters within each row indicate significant differences by Fisher`s LSD post hoc test.

4Unidentified terpene.
