WebOct 16, 2024 · These are called hypogeal cotyledons. Epigeal Cotyledons: Meaning and Function Epigeal cotyledons are cotyledons that emerge from the ground while the stem is growing after germination. WebThe germination in this species is hypogeal – i.e., in normal seedlings the cotyledons remain beneath the germination medium, while the plumage pushes upwards and emerges above. The seedlings are raised in seedbeds or polypots. Mulching of the beds is helpful. Seedlings attain a height of 25–30 cm in a year. how to scroll sideways excel
