Kinetic parameters K_m and V_max for NO₃⁻ absorption as determined at 35 DAG in rice plants (Piauí variety) with and without inoculation with different dark septate fungal isolates.

Treatment	Vmax (μmol g−1 h−1)	Km (μmol L−1)
Control	56.5 ± 4.4 a	88.6 ± 4.1 a
A101	55.1 ± 3.0 a	49.7 ± 10.8 bc
A103	46.8 ± 3.2 a	22.0 ± 3.4 c
A104	60.6 ± 16.5 a	76.4 ± 14.8 ab
A105	48.4 ± 2.7 a	96.1 ± 11.9 a
CV (%)	25.81	26.21

Means ± SE (n = 4) followed by the same lower-case letters in the column do not differ significantly (t-test (LSD), p < 0.05). The means of four composed repetitions (each repetition had four plants per pot). SE, standard error.
