A bimodal radial growth (RG) pattern, i.e., growth peaks in spring and autumn, was repeatedly found in trees in the Mediterranean regions, where summer drought causes reduction or cessation of cambial activity.

A resumption of cambial activity after intense summer rainfall was not observed in this region. In a field experiment, w
