Fig. 1. Original (left) and adjusted (right; by removing
effects of total mass) mean values (± SE) of plant root mass (grey) and
shoot mass (white) at low, medium and high densities in infertile and
fertile soil conditions at 30, 50 and 70 d of growth. Different letters
denoted significant differences between density treatments (p
< 0.05) within each soil condition and stage.
Fig. 2. Original (left) and adjusted (right; by removing
effects of total mass) mean values (± SE) of root:shoot ratio for
individuals at low (white), medium (grey) and high (black) densities
under infertile and fertile soil conditions at 30, 50 and 70 d of
growth. Different letters denoted significant differences between
density treatments (p < 0.05) within each soil condition and
stage.
Fig. 3. Original (left) and adjusted (right; by removing
effects of total mass) mean values (± SE) of main root diameter (MRD),
lateral root length (LRL) and number (LRN) at low (white), medium (gray)
and high (black) densities under infertile and fertile soil conditions
at 50 and 70 d of growth. Different letters denoted significant
differences between density treatments (p < 0.05) within each
soil condition and stage.
