Figure 6: The schematic diagram of tree dieback processes.
From: The dynamics of carbon stored in xylem sapwood to drought-induced hydraulic stress in mature trees
When the amount of NSCs in the sapwood decreases due to drought, xylem hydraulic dysfunction does not recover following water supply, resulting in tree dieback induced by hydraulic failure. On the other hand, when the amount of NSCs is still remained at above a threshold level during drought, xylem dysfunction is recovered following water supply, resulting in survival after the drought.
