Table 1.
Results of two-way ANCOVA on total dry weight and stem height, and results of two-way ANOVA on leaf size with aquatic adventitious root (AR) removal (Vaseline and removal treatments vs. intact and wounding treatments) and damage (Vaseline and intact treatments vs. removal and wounding treatments) as main effects; for the analysis of total dry weight and stem height, initial stem height was included as a covariate
