The effects of flufenamate and quinine on Na⁺ influx into 12-d-old excised roots of Arabidopsis

Values represent mean ± se (n = 18 for the controls, n = 6 for all other treatments). FM, Fresh mass.

Treatment	Na+ Influx
	0.05 mM Ca2+	0.2 mM Ca2+	3.0 mM Ca2+
	μmol g−1 FM min−1
Control	3.00 ± 0.26	1.88 ± 0.12	1.34 ± 0.19

1 mm Quinine	1.0 ± 0.09a	1.40 ± 0.14b	0.65 ± 0.08c

^a,b,c When statistically significantly different to the respective controls, P < 0.05.
