37. What is epigeal seedling growth?
38. What is hypogeal seedling growth?
Solution
Epi and hypo signify above and under as their literal meaning.
Epigeal: In epigeal germination, hypocotyl elongates and forms a hook. Hypocotyl extends and
the cotyledons and apical meristem are pushed out of the ground. After reaching the surface, the
cotyledons and the shoot tip are pulled up into the air. Here, the cotyledons become
photosynthetic and are also called seed leaves, examples are tamarind, papaya and beans.
Hypogeal: In hypogeal germination, the epicotyl elongates and forms the hook and the
cotyledons stay in the ground. The cotyledons eventually decompose and provide a food source
for the growing plant. The leaves start to form from the plumule and are also called as true
leaves. Examples are peas, gram, mango and faba bean..
