Table I.

VOCs in the headspace of JA-treated and BTH-treated plants

Amounts are given in nanograms released per gram leaf dry weight in 24 h (±se). Asterisks mark VOCs that after BTH treatment were released at significantly higher rates than after JA treatment (P < 0.05 according to Wilcoxon pair tests conducted for individual compounds; n = 7 plants per treatment).
