On the Relationship between Pollen Size and Genome Size
Table 2
Contribution index scores (with rank) for divergences in pollen width and 1C DNA content for the species in our sample.
| Rank | Pollen width contribution | Divergences making the largest contribution | 1C DNA | 1C DNA | content | content | rank | contribution |
| 1 | 0.134 | Angiospermae versus Acrogymnospermae | 1 | .384 | 2 | 0.050 | Polytomy at the origin of Coniferae | 194 | <.001 | 3 | 0.046 | Divergence at the origin of Papilionoideae | 99 | <.001 | 4 | 0.041 | Divergence between Lythraceae and Onagraceae | 138 | <.001 | 5 | 0.036 | Magnoliidae versus Eudicotyledonae | 3 | <.001 | 6 | 0.032 | Divergence of Fagaceae and the rest of Fagales | 81 | .002 | 7 | 0.031 | Polytomy at the origin of eurosid II | 127 | .002 | 8 | 0.030 | Divergence between Zingiberales and Poales | 175 | .002 | 9 | 0.026 | Divergence between Solanales and Lamiales | 35 | <.001 | 10 | 0.026 | Divergence at the origin of Malvaceae | 136 | .002 |
