A Three- way ANCOVA of species (S, df = 9), water (W, df = 1) and light (L, df = 1) as main factors and relative growth rate, biomass allocation, morphological and leaf physiological traits as dependent variables.

Plant dry mass was included in the ANOVA as a covariate for all variables but RGR, and beta is the regression coefficient of the slope. F-value, significance levels and R2 of the model are shown. *:p ≤ 0.05 **: p ≤ 0.01 ***: p ≤ 0.001 ND = not determined. Leaf mass fraction, stem mass fraction and root mass fraction were arcsine transformed and all other traits were log10 transformed prior to analysis.
