Table 3.

Relative allocation of starch, soluble sugars (SS) and nitrogen (N) to roots and shoots of species with different rooting and sprouting abilities

Disturbance response	n	Starch	SS	N
Shoot rooting ability:
Rooting	10	1·1 (0·5)	1·8 (1·2)	1·2 (0·3)
Non-rooting	8	1·4 (0·5)	1·8 (1·3)	1·2 (0·3)
Root-sprouting ability
Root-sprouters	6	1·3 (0·5)	1·9 (1·2)	1·2 (0·3)
Non-root-sprouters	12	1·2 (0·4)	1·7 (1·3)	1·2 (0·3)
Sprouting after clipping:
Non-sprouters	8	1·2 (0·5)	1·8 (1·5)	1·1 (0·2)
Resprouters	10	1·3 (0·4)	1·8 (1·2)	1·3 (0·3)
Root- versus stem-sprouters
Root-sprouters	6	1·3 (0·5)	1·9 (1·2)	1·2 (0·3)
Stem-sprouters	4	1·1 (0·3)	1·5 (0·9)	1·3 (0·3)

Mean values of the quotient between root and shoot concentrations are shown along with standard deviations (in parentheses). Values in bold indicate significant differences between groups after a nested ANOVA (P < 0·05; see text for further details on calculations).
