Table 3.
ANOVA of the effects of pollination type (selfed vs. open) and host species mixture on the biomass of R. alectorolophus
| Source of variation | d.f. | Parasite biomass |
|
|---|---|---|---|
| MS | F | ||
| Pollination | 1 | 0·114 | 0·53 |
| Mixture | 14 | 1·421 | 6·61*** |
| Pollination × mixture | 14 | 0·335 | 1·56+ |
| Pollination × number of legumes | 1 | 0·110 | 0·513 |
| Pollination × number of functional groups | 1 | 1·072 | 4·991* |
| Rest | 12 | 0·292 | 1·359 |
| Residual | 136 | 0·215 | |
For a better understanding of the pollination × mixture interaction, the effect of mixture was partitioned into the three linear contrasts number of legumes in the mixture, number of functional groups and the residual variation among mixtures.
