DW: dry weight; N: number; L length; D: diameter; Sd: seedling; Nd needles; St stem; PR: main root; LR: lateral roots; SR: short roots; K: permeability; n: porosity; ρ_d: bulk density; ρ_sat: density at saturation; WHC: water-holding capacity. Bilateral correlation is significant at the P < 0.01 () or P < 0.05 () level.
