ANOVAs for the effects of area, site, burial height, nutrient availability and their interactions on morphological and growth variables of <i>Sporobolus virginicus</i> clones.

a, b, cDenote post-hoc pooling, P>0.25; new F-values are given for those tested against the pooled term. Results of SNK tests are also reported. NB = no burial, AC = artifact control, CB = complete burial, PB = partial burial. A1, A2 = area 1 or 2, S1, S2 = site 1 or 2, N− = no nutrient added, N+ = nutrient added. * = P<0.05, ** = P<0.01. § = variances were heterogeneous (Cochran’s C test, P<0.05) and α = 0.01 was adopted.
