Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. ... Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions.
Is dormancy an adaptation?
Dormancy in higher plants is an adaptive response, evolved in the species' origin environment, enabling survival during seasons when environmental conditions are most threatening (Vegis, 1964).
What are the two types of seed dormancy?
There are two different categories of seed dormancy: exogenous and endogenous (Scarification). Exogenous dormancy is caused by conditions outside of the seed's embryo. An example of exogenous dormancy is when the seed coat is too durable for moisture to infiltrate, effectively preventing germination.
What is seed and bud dormancy?
Importance and Significance • Physiology of Dormancy During the developmental cycle of the plant, at some phase or the other certain structures like buds, tubers, seeds, etc., go through a period of temporary suspension of growth activity. ... Such a state is called dormancy.
What is dormancy and its types?
The seed dormancy is of following types: Innate dormancy. It is the condition of seeds which is incapable of germination even if conditions suitable for seedling growth are supplied. This inability to germinate may be due in certain species to the embryo being immature at the time of dispersal. Enforced dormancy.

Is a seed alive or dead?
Seeds are living things as they contain an embryo that is capable of germinating to produce a new plant under optimum temperature, humidity and availability of water. If seeds were not alive, they would not have been able to germinate, give rise to seedlings and develop into mature plants.
How do you overcome dormancy?
Treatments to Overcome Seed Dormancy
- Mechanical Scarification.
- Hot Water Scarification.
- Drop into hot water (77 to 100oC), remove from heat, allow to cool and soak for 24 hours.
- Acid Scarification.
- Seeds, in small batches, are brought into contact with 93% Technical Grade sulphuric acid. ...
- Warm Moist Scarification.
Which chemical is used to break seed dormancy?
The chemicals which are used commercially in various places are including: potassium nitrate, thiourea, sulfuric acid, ethanol and cyanamid. All of these chemicals are inexpensive and can be used easily to break the true dormancy of seeds effectively (Chang and Sung, 2000).
