Note: SE: standard error, LL/HT: lesion length/seedling height, OL/HT: occlusion length/seedling height, HTI: height growth, Ny: needle dry biomass, Sy: stem dry biomass, and FRY: fine root dry biomass. Different letters indicate Tukey pair-wise differences among watering treatments within each variable at α = 0.05.
