- Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.
What are the 5 stages of germination?
Such five changes or steps occurring during seed germination are: (1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators and (5) Development of Embryo Axis into Seedling.
How does germination start?
Germination begins with imbibition , a big word for taking in water. This is the major trigger to start the period of waking up from dormancy. As the seed takes in water, it gets bigger and produces enzymes. ... The seed grows, and the radicle, or first stage of the root, emerges from the seed.

What is germination explain with diagram?
1) Imbibition: water fills the seed. 2) The water activates enzymes that begin the plant's growth. 3) The seed grows a root to access water underground . 4) The seed grows shoots that grow towards the sun. 5) The shoots grow leaves and begin photmorphogenesis.
What are 2 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.
Why is germination important?
Seed germination starts with imbibition, when the seed takes in water from the soil. This triggers root growth to allow the seed to get more water. ... Seed germination is important for natural plant growth and growing crops for human use .
What is not needed for germination?
