Seed germination:
The fundamental process by which a seed grows into a new plant is called seed germination.
Sometimes even after providing appropriate conditions like oxygen, water, and temperature, several viable seeds do not germinate as they are in a state of dormancy.
Many seeds have developed a dormancy period.
Seed dormancy is a condition that prevents germination even when optimal environmental conditions are provided.
Different factors can break this dormancy – light is essential for germination.
Some plants require to break their physical or chemical dormancy factors. Seeds might have a hard or thick seed coat (physical dormancy).
The breaking through or scarring of the seed coat before seeds germinate.
