Protonated masses, tentative identification, molecular formula, emission value (ncps) for treated and untreated plants with standard deviation (SD) and references of the investigated volatile compounds. Significant differences between the means appear with different letters, small for intra-treatment and capital for inter-treatment comparisons (at least p < 0.05).
