Fig. 4. Additional additive and substitutive comparisons ('mixed additivesubstitutive design', MASD) for selected treatments from replacement series experiments, analysable with ANOVA. A hypothetical example is presented here where the intra- and interspecific effects on the yield of an initial 250 F, t.rsiculosus germlings (symbolized as black area indicated with an arrow) is given. 'A' compares the interspecific effect of adding 500 F. srrrutus, 'B' the intraspecific effect of adding 500 F. crsiculo.rus. 'C' and 'D' depict substitutive comparisons between intra- and interspecific effects at medium density = 500 and high density = 1000 shoots, 10 x 10 cm, respectively. E, F: included as 'unplanned comparisons' in one-way ANOVA but irrelevant, since total density and species combination are changed simultaneously. For meaning of abbreviations (e.g. "SV 0:4 High Density") see Table 1. Note that germlings of 2 species are interdispersed in mixtures and not clumped in separate corners as symbolized here.
