2.2 Volatile Infochemicals from Plants
2.1.1 Composition of Volatile Bouquets from Intact and Damaged Plants
In the headspace of intact plants generally between 10 to over 100 volatile compounds occur (Schoonhoven et al. 1998). The major groups of compounds
released are six-carbon alcohols, aldehydes and esters of acetate and other short-
