![]() Plants that show epigeal germination grow relatively fast, especially in the first phase when the leaflets unfold. Therefore they can be found more often in the field, at the border of forests, or as pioneer species. The plants also need relatively more sunlight for photosynthesis to take place. Plants that show epigeal germination need external nutrients rather quickly in order to develop, so they are more frequent on nutrient-rich soils. The evolutionary strategy is that the plant produces a large number of seeds, of which statistically a number survive. īecause the cotyledon is positioned above the ground it is much more vulnerable to damage like night-frost or grazing. ![]() Instead, the first leaflets are already folded up inside it, and photosynthesis starts to take place in it rather quickly. Normally, the cotyledon itself contains very few nutrients in plants that show this kind of germination. In this way, the hypocotyl pushes the cotyledon upward. The hypocotyl elongates while the epicotyl remains the same in length. | Epi: Above + Geo: Earth | + GerminationĮpigeal germination implies that the cotyledons are pushed above ground. The opposite of epigeal is hypogeal (underground germination). An example of a plant with epigeal germination is the common bean ( Phaseolus vulgaris). Epigeal germination ( Ancient Greek ἐπίγαιος 'above ground', from ἐπί 'on' and γῆ 'earth, ground') is a botanical term indicating that the germination of a plant takes place above the ground.
