Internode numbers at the start and the end of treatments (means ± S.E. n = 20).

Submergence depth (m)	Internode numbers		New internode numbers
	Before submergence	After submergence
0	12.50 ± 0.21a	14.40 ± 0.22a	1.85 ± 0.08b
2	12.30 ± 0.25a	14.60 ± 0.29a	2.40 ± 0.11a
5	12.20 ± 0.25a	14.00 ± 0.25a	1.85 ± 0.13b
9	12.40 ± 0.22a	12.75 ± 0.27b	0.30 ± 0.11c

Different lower-case letters indicate significant differences (p < 0.05) between submergence depths.
