Means followed by the same superscript letter within columns are not significantly different (P < 0·05).

Ψleaf, leaf water potential; gs, stomatal conductance; Kpa, whole-plant hydraulic conductivity; Lp, root hydraulic conductivity.

In aerobic30 and aerobic80 treatments, irrigation was applied when the soil water potential reached –30 kPa and –80 kPa, respectively.
