Peach (Prunus persica) was chosen as a model to further clarify the physiological role of jasmonates (JAs)
during fruit ripening. To this aim, the effect of methyl jasmonate (MJ, 0.88 mM), applied at a late stage (S3)
of fruit development under field conditions (in planta), on the time-course of fruit ripening over a 14-day
period was evaluated.
