What are the 2 types of germination?

There are two types of germination:

  • Epigeal Germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil.
  • Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil.

What are the examples of Hypogeal germination?

In peas and corn (maize) the cotyledons (seed leaves) remain underground (e.g., hypogeal germination), while in other species (beans, sunflowers, etc.)

What is germination give example?

Epigeal and hypogeal are two types of germination in which epigeal is germination that brings cotyledons out of the soil surface, one example of plants that experience epigeal germination is green beans, while hypogeal is germination which perpetuates cotyledons in the soil, one example of plants that have germination …

What is Vivipary germination?

In plants, vivipary (precocious or premature germination) involves the germination of seeds while still on the parent plant. It is a widespread phenomenon in plants characterized by the lack of seed dormancy.

Why don t seeds germinate inside the fruit?

The phenomenon of seeds not germinating until some condition is fulfilled is called dormancy. Sometimes, a component of the fruit flesh actually maintains the dormancy and needs to be cleaned off well to allow germination.

Why do seeds germinate inside fruit?

Vivipary happens when the hormone controlling the seed dormancy is exhausted or runs out, letting the seed grow in the moist environment inside the fruit. This warm, moist environment is perfect for germinating seed to grow. Check out the seeds inside your fruit or vegetable the next time you slice into it.
