Types of Germination: Epigeal and Hypogeal
Epigeal Germination:
Epigeal germination occurs when the radicle emerges from the seed coat and grows upwards. The radicle then breaks through the soil surface and develops root hairs. Epigeal germination is observed in most vascular plants, such as grasses and lilies. Examples of epigeal germination include:
Seeds of corn and wheat
Seeds of milkweed
Seeds of foxglove
Hypogeal Germination:
Hypogeal germination occurs when the radicle emerges from the base of the seed coat and grows downward. The radicle then grows down through the soil and develops root hairs. Hypogeal germination is observed in some non-vascular plants, such as ferns and mosses. Examples of hypogeal germination include:
Seeds of oak and maple trees
Seeds of sedum and cattails
Seeds of certain ferns and mosses
