Photodormancy or light sensitivity affects germination of some seeds. These photoblastic seeds need a period of darkness or light to germinate. In species with thin seed coats, light may be able to penetrate into the dormant embryo.

What is the meaning of seed dormancy?

Seed dormancy is defined as the inability of intact viable seeds to complete germination under favorable environmental conditions (Gao and Ayele, 2014).

What is dormancy and why it is important?

Dormancy helps seeds to remain alive in the soil for several years and provides a continuous source of new plants, even when all the mature plants of the area have died down due to natural disasters.
