Web29 aug. 2024 · Hypogeal germination is a type of germination whereby cotyledons or the seed leaves do not emerge on the surface, they just remain underground. This is usually due to the rapid development and elongation of the epicotyl. The epicotyl is generally the embryonic shoot above the cotyledons. The evolutionary strategy is that the plant produces a relatively low number of seeds, but each seed has a bigger chance of surviving. Plants that show hypogeal germination need relatively little in the way of external nutrients to grow, therefore they are more frequent on nutrient-poor soils.
