Effect of methyl jasmonate on ethylene and volatile production by Summerred apples depends on fruit developmental stage.

Pre- and postclimacteric Summerred apples, harvested 91, 99, 106 and 113 days after full bloom (DAFB) from a research orchard near Wenatchee, WA, USA, were exposed for 12 h to a low concentration of atmospheric methyl jasmonate (2 x 10-7 mol/litre at 20 deg C). Ethylene and volatile production by fruits were measured at harvest and for 15 days at 20 deg after treatment. Responses to methyl jasmonate treatment depended on the stage of fruit development. Methyl jasmonate stimulated ethylene, ester, alcohol and acetic acid production in preclimacteric fruits (91 and 99 DAFB), while little or no response was elicited from postclimacteric fruits (106 and 113 DAFB). Ketone and aldehyde emissions were not affected by methyl jasmonate regardless of developmental stage.
