- •
We provide an example of wide variability in seed germination traits for an aluminium accumulator species.
- •
Variability was detected for germinability, coefficient of variation of germination time and uncertainty.
- •
We provide an example of one calcifugous, Al and Mn accumulator species with high content of iron in the leaves.
- •
We hypothesize that endogenous Al of the seeds could be sufficient to trigger germination in Al-accumulators
