Leaf volatiles were obtained by extraction with pentane and analyzed by means of GC-MS (n = 6). The values indicate the means and ses of each volatile identified. The results were evaluated by means of ANOVA. P-values marked with an asterisk (^*) denote compounds that were found in significant different amounts. Compounds marked with footnote ^a designation were not available as pure standard and their amounts had to be estimated on the basis of the compound closest on the retention time scale of the chromatogram, providing it was of the same chemical class and a pure standard was available.
