Effects of ethylene and (Z)-hexen-3-al on production of volatiles in Populus simonii × P. pyramidalis ‘Opera 8277’ cuttings

Abstract

We studied the effects of ethylene, (Z)-hexen-3-al, combinations of ethylene and (Z)-hexen-3-al, methyl jasmonate on the release of terpenoids and green leaf volatiles (GLVs) of Populus simonii × P. pyramidalis ‘Opera 8277’ by fumigation. The results show that exposure to ethylene alone did not induce volatiles. However, it was induced by exposure to combinations of (Z)-hexen-3-al and ethylene, a large amount of hexenal and hexen-3-ol as compared to sole (Z)-hexen-3-al exposure, which indicated that the release of wounding signals of P. simonii × P. pyramidalis‘Opera 8277’ could be synergized by ethylene and (Z)-hexen-3-al.
