TABLE 2.

Fine root morphology obtained from IG_total.

Position	Treatment	Root diameter (mm)	SRL (m g–1)	RTD (g cm–3)
Top part	Control (n = 9)	0.45 ± 0.03a	27.0 ± 2.0a	0.25 ± 0.02a
	Partial-WL (n = 10)	0.52 ± 0.01a	23.7 ± 4.0a	0.24 ± 0.03a
	Full-WL (n = 7)	0.52 ± 0.02a	22.5 ± 1.7a	0.22 ± 0.01a
Bottom part	Control (n = 10)	0.42 ± 0.01a	26.0 ± 2.0a	0.29 ± 0.02a
	Partial-WL (n = 10)	0.49 ± 0.02b	23.3 ± 1.1a	0.24 ± 0.01ab
	Full-WL (n = 9)	0.50 ± 0.02b	22.3 ± 2.0a	0.24 ± 0.01b

Mean (±SE) root diameter, specific root length (SRL), and root tissue density (RTD) obtained from IG_total (n = 7–10) of control, partial waterlogging (partial-WL), and full waterlogging (full-WL). Values in black show results obtained from non-waterlogged soils, and values in blue show results obtained from waterlogged soils. Statistical difference among treatments was tested at the top part and the bottom part, respectively. Results of the Tukey–Kramer’s multiple comparison test or Steel–Dwass multiple comparison test (top and bottom of RTD) are shown with different italic letters indicating statistical differences between treatments (p < 0.05).
