Seed mass, germination percentages and rate of germination (Timson’s Index) of seeds from differed umbel (primary and secondary) and umbellet position (outer and central).
| Habitat | Umbel order | Umbellet position | Individual seed mass (mg)* | Final germination (%)* | Rate of germination (%)* |
|---|---|---|---|---|---|
| Roadside | Primary | Outer | 5.6 ± 0.3a | 81 ± 3a | 58 ± 3a |
| Central | 4.6 ± 0.2b | 64 ± 4b | 56 ± 2a | ||
| Secondary | Outer | 4.9 ± 0.2ab | 66 ± 3b | 55 ± 4a | |
| Central | 3.7 ± 0.3c | 53 ± 5c | 52 ± 3a | ||
| Forest | Primary | Outer | 6.9 ± 0.2a | 86 ± 3a | 66 ± 6a |
| Central | 5.1 ± 0.5c | 69 ± 5b | 65 ± 4a | ||
| Secondary | Outer | 5.9 ± 0.5b | 79 ± 6b | 67 ± 4a | |

Germination data (mean ± SD) are from laboratory trials at 22 °C/10 °C with 14/10 h light treatment.
*The values followed by the same letter within a column do not differ significantly by ANOVA followed by Tukey’s test at p < 0.05 in the same habitat.
