SEED DORMANCY AND ITS IMPORTANCE

Seed is an important part of crop’s life cycle as it establishes the next generation. Seed dormancy defined as that time gap during which seeds will not germinating even in  the required favourable condition such like temperature, humidity, oxygen and light.This is due to lack of supply of certain enzymes that seed gets to dormant stage. Dormancy is an important factor limiting production in many field crops. In order to break the  dormancy we can try several chemical and physical pretreatments to seed and other propagation material.

Two type of dormancy can be there in a seed.

1. Seed coat (Physical) dormancy and

2. Internal dormancy

There are some of methods to breakdown the dormancy in the seed.

1. Natural breaking of dormancy and

2. Artificial overcoming of seed dormancy

Special treatment can also be given to seed to break down the dormancy like seed coat treatment, Embryo treatment and Chemical treatment.

Importance of seed dormancy

Dormancy helps the seed to live alive in soil for several years. Dormancy is very useful for desert plant because of inhibitors present in it. Therefore dormancy acts as survival mechanism for plant. Dormancy increases the seed vigor without any harm during cold or high summer temperature and drought condition.
