Epicotyl - Wikipedia
An epicotyl is important for the beginning stages of a plant's life. It is the region of a seedling stem above the stalks of the seed leaves of an embryo plant. It grows rapidly, showing hypogeal germination, and extends the stem above the soil surface.
Epicotyl | plant anatomy | Britannica
An epicotyl, which extends above the cotyledon (s), is composed of the shoot apex and leaf primordia; a hypocotyl, which is the transition zone between the shoot and root; and the radicle. Angiosperm seed development spans three distinct generations, plus a new entity: the parent sporophyte, the…

Epicotyl Emergence: Understanding the Key Stage of Seed …
Epicotyl emergence refers to the process in which the epicotyl breaks through the surrounding seed coat and soil, enabling the aboveground growth of the seedling. It marks the transition from the underground seed phase to the establishment of the seedling in its aboveground environment.
4.6.3: Mature Embryos and Seed Structure - Biology LibreTexts
The portion of the embryonic axis between the cotyledon attachment and the shoot tip is the epicotyl (epicotyl means "above the cotyledons; Figures \(\PageIndex{2-3}\))). Some embryos lack a visible epicotyl because the cotyledons are attached to the embryonic axis at the shoot tip.
Epicotyl vs. Hypocotyl - What's the Difference? | This vs. That
The epicotyl is responsible for the growth of the shoot system, including the stem, leaves, flowers, and fruits. In contrast, the hypocotyl is primarily involved in the growth and establishment of the root system, as well as the emergence of the seedling from the soil.
