The last ANOV table was constructed for the variable
representing leaf area missing, in which case this was the
dependent variable. Leaf area was significant at .01 in
both analyses, i.e. in both the limited model and when all
independent variables were included in the model (Table 18).
The partial sums of squares indicated that the following
independent variables were significant sources of variation
at the .01 probability level: Alkalinity, iron, nitrates,
Vogtia and Agasicles. Turbidity and phosphates were
