Mean (±se) WP cis-α-bergamotene
trapped per hour, per liter air sampled from individual (eight per
treatment) N. attenuata (A) plants and mean
(±se) JA concentrations (n.d., not determined) of node two
leaves of four replicate plants per treatment 35 min (time of maximum
JA induction; B) after the node two leaf was wounded and treated with
20 μL of the following test solutions: water (W), oral secretions and
regurgitant from M. sexta larvae (M.s.) or M.
quinquemaculata (M.q.), exR, Triton X-100 in water (T), FAC in
concentrations found in R and FA in concentrations found in R in the
triton solution or in exR. Control plants (C) remained undamaged. Stars
represent significantly (P < 0.05) increased emissions
as compared with wounded plants treated with water (W) as determined by
Fisher's protected least significant difference from
ANOVAs.
