Table 5

Pearson correlation coefficients between soil hydromechanical characteristics and root tissue width at 5% risk of the error.

		K (cm s^−1)	n	ρ d (g cm^−3)	ρ sat (g cm^−3)	WHC (%)
Width (µm)	Epidermis	−0.118	−0.705	0.537	0.431	−0.555
	Cortex	−0.425	−0.887	0.770	0.681	−0.860
	Vascular bundle	−0.157	−0.833	0.738	0.662	−0.704

K: permeability, n: porosity, ρ_d: bulk density, ρ_sat: density at saturation, and WHC: water-holding capacity. Bilateral correlation is significant at the () or () level.
