The term germination designates the overall processes showtime amongst the imbibition of H2O yesteryear dry out seed together with ending when a component of the embryo penetrates the seed coat. This procedure include prison theatre cellphone division, embryo enlargement together with increase inwards metabolic activities.
There are 2 types of germination: Epigeal together with Hypogeal
Example: Bean, Castor
1. In this type of germination, the seed /cotyledons emerge out of the reason or higher upwards the soil.
2. The cotyledons plow light-green (photosynthetic) together with deed equally firstly leaves of the plant.
3. There is greater elongation of the hypocotyl.
4.The lastly piece of occupation of hypocotyl is curved to protect the plumule from the friction of the soil.
5. Energy for growth primarily derived from cotyledon
Hypogeal Germination: (hypo (Gk) way below, geal (Gk): earth)
Example : Pea, Maize, Coconut
1. In this type of germination, the seed/ cotyledons rest within the reason or below the soil.
2. The cotyledons play no piece of occupation inwards photosynthesis.
3. There is greater elongation of the epicotyl.
4. The lastly piece of occupation of the epicotyl is curved to protect the plumule from friction.
5. Energy for growth primarily derived from endosperm
