WebJun 27, 2024 · Seed germination is a critical step in the life cycle of higher plants. During germination, viable seeds develop into plants upon imbibition in water, which then allows for embryo growth until the radicle breaks through the peripheral tissue structures (endosperm and seed coat; Bewley et al., 2013).
