Effects of AVG on shoot elongation of arrowhead tubers at different concentrations of oxygen

Treatment
Oxygen conditions	50 mm AVG	Elongation (mm)
Air	−	4·6 ± 0·8
	+	2·2* ± 0·4
1 % O2	−	10·2 ± 0·5
	+	7·4* ± 0·7
N2	–	10·5 ± 0·8
	+	9·1 ± 0·8

Elongation was measured after incubation for 2 d in the dark. Data are the means ± s.e. of 21–25 determinations in four different experiments. Asterisks show significant differences at P < 0·05 between treatments with and without AVG at the same oxygen concentrations.
