Table 2.

VOCs induced by the commercial elicitors Bastid®, Redeli®, and Romeo ®. List of the VOCs induced (FC > 1.5 compared to the water control) at least twice by Bastid®, Redeli® or Romeo ® treatment (three replicates/treatment). Coloured boxes indicate average elicitor/H2O induction ratios 1, 3, and 5 days post treatment (D1, D3, and D5), with ■ fold change (FC) < 1.5 (not induced); ■ 1.5–102; ■ 102–103; ■ 103–104; ■ 104–105; ■ > 105, □ not detected. For each elicitor, fold changes were determined from the three replicates and averaged. For each elicitor, the frequencies of the FC > 1.5 ratios were summed from the three replicates for each day post-treatment (D1, D3 and D5), and represented as follows: none = never detected; ◯ = 1, detected in one replicate with FC > 1.5 on the corresponding day post treatment; ● = 2, detected in two replicates with FC > 1.5 on the corresponding day post treatment; and ● = 3, detected in three replicates with FC > 1.5 on the corresponding day post treatment. Bold type, VOCs significantly induced by Bastid® (Table 1). The CAS number (CAS #) of each VOC is indicated. “Group” indicates the elicitor(s) when the VOC fitted at least two ◯ and/or one ●.
