WebEpigeal germination implies that the cotyledons are pushed above ground. The hypocotyl elongates while the epicotyl remains the same in length. In this way, the hypocotyl pushes the cotyledon upward. Normally, the cotyledon itself contains very little nutrients in plants that show this kind of germination.
WebHypogeal germination. In this type of germination, the cotyledons remain below the soil due to rapid elongation of epicotyl. It is found in many dicotyledonous seeds and monocotyledonous seeds.
