  1. Values represent means ± SE (n = 3).
  2. Partitioning among C6 alcohols, benzenoids, terpenes and C13-norisoprenoids is expressed as percentages (%).
  3. Lowercase letters indicate statistically significant differences at a 5% level of significance.
  4. (Tukey’s HSD test); n.s. = not significant.
