Hi mate
Germination is the budding of a seed after it has been planted in soil and remained dormant for a certain period of time. For plants and fruits that reproduce through seeds and pollen, the seeds eventually grow into young plants through the process of seed germination. When seeds are planted, they remain inactive until conditions are suitable for germination.
For germination to occur various conditions must be met such as the proper amounts of water, oxygen, temperature, and light. When these conditions are met, the seed begins to enlarge as it takes in water and oxygen. The seed's coat breaks open and a root or radicle emerges from the seed, which is followed by a plant shoot. This initial stage of a plant’s development is germination.
There are two types of germination:
1. Epigeal Germination:
In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. Bean, cotton, papaya, gourd, castor and onion have germination of this kind.
2. Hypogeal Germination:
In this type of germination, the epicotyl elongates and the cotyledons remain below the soil. Pea, mango, maize, rice, gram and groundnut have germination of this kind.
