Note. SE: standard error, LL/HT: lesion length/seedling height, OL/HT: occlusion length/seedling height, HTI: height increase, BB: new bud-break, and Ny: needle dry biomass. Different letters indicate Tukey pair-wise differences between all watering treatment and inoculations within each variable at α = 0.05.
