Table I. Emission of the four major volatile compounds from leaves of 27 Arabidopsis accessions in response to treatment with coronalon (coron).
Volatiles were collected for 8 h from single intact plants (see “Materials and Methods”). Emission was determined in ng g−1 fresh weight h−1. Mean values ± se are shown (n = 3). The order of accessions corresponds to increasing (E)-β-ocimene emission rates. 0.0 indicates values below 0.01 ng g−1 fresh weight h−1. n.d., Not detected.
