What does imbibition refer to in plants?

Imbibition refers to the process where seeds or plant tissues absorb water, leading to their swelling and the initiation of germination. This is a crucial step for seeds because it activates metabolic processes that are essential for growth. When seeds imbibe water, they expand and become turgid, which prepares them for sprouting. The process also helps to soften the seed coat, allowing the embryo to emerge more easily.

Understanding imbibition is vital because it affects how a plant begins its life cycle. Without sufficient water absorption during this phase, seeds may not germinate effectively, impacting plant growth and development. This is particularly relevant in various agricultural contexts, as farmers must ensure that seeds receive adequate moisture for successful propagation.
