Understanding Quiescence

Quiescence refers to a resting phase in which a non-dormant seed halts its development and shows no signs of activity. This phase is triggered by the lack of favourable conditions such as light, moisture, and suitable temperature. However, when these conditions improve, the seed's growth is resumed and the rate of cell division is restored.

Defining Dormancy

Dormancy, on the other hand, is a phase where viable seeds are stopped from growing due to harsh conditions. It acts as a protective measure, shielding seeds from potential damage caused by unfavourable conditions. This phase is seen as an adaptation of the seed. While it's a beneficial adaptation for the plant, it's not so favourable in the field of agriculture. The dormancy phase can be artificially reversed through chemical treatments.

Comparing Quiescence and Dormancy

Both dormancy and quiescence are phases that postpone the germination process to increase the seed's survival rate. Let's dive deeper into the distinctions between these two phases.
