In some forest systems, stomata have also been observed to reopen rapidly on recovery from drought, with delays in gas exchange recovery only observed once embolism-induced declines in hydraulic conductance occur ([29]). (B) When relief from a drought occurs after embolism has formed in the xylem then gas exchange recovery can take many months in species that must construct new xylem and organs to regain pre-drought gas exchange capacity ([3], [1]). [2] report that on rewatering from a drought severe enough to close stomata, the complete recovery of leaf gas exchange took >7 days, yet water potentials recovered within 12 h of rewatering.
