Abstract EN
We compared potential germination success (i.e., percentage of produced seeds that germinate under optimal conditions), the percentage of empty and insect-damaged seeds, germinability (Gmax), and time to germination (Tgerm) between the exotics Ailanthus altissima, Robinia pseudoacacia, and Ulmus pumila and two coexisting native trees (Fraxinus angustifolia and Ulmus minor) in the riparian forests of Central Spain.
Additionally, we tested the effect of seed age, seed bank type (canopy or soil) and population on Gmax and Tgerm of A.
altissima and R.
pseudoacacia, which are seed-banking species.
Species ranked by their potential germination success were A.
altissima > U.
pumila > R.
pseudoacacia > U.
minor > F.
angustifolia.
The combination of a high Gmax and negligible seed insect-damage provided A.
altissima with a potential germination advantage over the natives, which were the least successful due to an extremely high percentage of empty seeds or a very low Gmax.
R.
pseudoacacia showed high vulnerability to insect seed predation which might be compensated with the maintenance of persistent seed banks with high Gmax.
Gmax and Tgerm were strongly affected by seed age in the seed-banking invaders, but between-seed bank variation of Gmax and Tgerm did not show a consistent pattern across species and populations.
