Definition of Germination
Process of imbibition and absorption of water, hydration of tissues, absorption of oxygen, activation of enzymes and digestion, transport of nutrients to embryo axis, increase in respiration, cell division & growth and embryo emergence
4 key points of Germination
Hypogeal Germination
Occurs in Grass, Maize, Wheat, etc
Involves the elongation of the epicotyl(cotyledons remain below soil surface)
Epigeal Germination
Occurs in Beans
Involves the elongation of the hypocotyl (cotyledons push above soil surface)
