Definition of hypogealCategorized under "General"
Definition as written by bluespiral:
Hypogeal refers to seeds that will not form leaves unless they first experience a period at 40*F, after which they will produce a leaf at 70*F. Generally, the seed is exposed to a sequence of 70*F-40*F-70*F for 3 months each, during which the root (radicle) forms during the first 70*F period and the leaf during the second 70*F period.
Definition as written by Mitchella:
Hypogeal refers to any seed (not just lilies) whose cotyledon germinates and remains under the surface of the soil, e.g. corn. It is the opposite of epigeal, where the cotyledons emerge from the soil upon germination, e.g. beans. It has nothing to do with temperature requirements for germination.
