The seeds germinate above ground ( epigeal germination ) around 15 days after being sown.
2.
After the slower first phase, the plant develops faster than plants that show epigeal germination.
3.
Plants that show epigeal germination grow relatively fast, especially in the first phase when the leaflets unfold.
4.
Plants that show epigeal germination need external nutrients rather quickly in order to develop, so they are more frequent on nutrient-rich soils.
5.
In botany, a seed is described as showing "'epigeal germination "'when the cotyledons of the photosynthetic above the ground.
6.
In botany, a seed is described as showing "'hypogeal germination "'when the cotyledons of the photosynthetic above the ground, is "'epigeal germination " '.
7.
However, the seeds of " A . bidwillii " are much larger, long and wide, than the seeds of " A . mirabilis " . " A . bidwillii " also exhibits cryptocotylar hypogeal germination ( the cotyledons are non-photosynthetic and remain in the shell on germination ), while there is evidence that indicates that " A . mirabilis " and other extinct members of the section " Bunya " exhibited epigeal germination ( the cotyledons are photosynthetic and expand above-ground ).
