Hypogeal Germination

Germination is the fundamental process in which the sown plant seeds are grown into young plants or seedlings. Based on their growing conditions and the fate of the cotyledons, the process of germination is classified into two main types:

  1. Epigeal Germination
  2. Hypogeal Germination

What is Hypogeal Germination?

Hypogeal germination is a type of seed germination, which is typical for both the monocot and dicot seeds, where the cotyledons remain inside the soil.

The term Hypogeal germination is derived from the ancient Greek word, which refers to the below ground.

Hypogeal Germination

The Process of Hypogeal germination is described as:

During hypogeal germination:

  • The cotyledons – a significant part of a seed embryo, remains under the soil.
  • The plumule– the rudimentary shoot tip arising from the seed embryo emerges above the ground.
  • The plumule arises out by pushing itself in the upward direction.
  • This continues with the epicotyl- the seedling stem above the cotyledon, which rapidly elongates its structure.

Pros and Cons of Hypogeal Germination

The advantage of hypogeal germination is that the plant or the seedlings are protected from early grazing and the drawback or the disadvantages of hypogeal germination is that the plant cannot begin to synthesize its own food or photosynthesize until the true leaves have completely appeared.

Hypogeal germination occurs in both monocotyledons seeds including paddy, wheat, maize, etc. and dicotyledons seeds, including pea, mango, groundnuts, etc.
