Time was used as covariate to analyse leaf area (LA) and dry biomass (W_p). Vapour pressure deficit was used as covariate for shoot water potential (Ψ), sap pH, stomatal conductance (g_s), leaf specific hydraulic conductance (LSC) and the percentage loss of hydraulic conductance (PLC). Different letters denote significant differences at P <0·05.

*Values were arcsin transformed for the analysis.
