Scarification is a pretreatment of seeds that aims to break seed dormancy and accelerate the occurence of uniform seed germination.
- Scarification involves weakening, opening or altering the coat of a seed to encourage the germination. It can be done mechanically, thermally and chemically. This will make the seed coat permeable for water and air, which will help in germination of seed.
- The process by which plants use a prolonged cold period-winter-to promote flowering is known as vernalization
Somewhere, all these processes are used to break the dormancy the seeds naturally as well as artificially.
