Imbibition is a special type of diffusion that takes place when liquid is absorbed by solids-colloids causing an increase in volume. Water surface potential movement takes place along a concentration gradient; some dry materials absorb water. A gradient between the absorbent and the liquid is essential for imbibition. For a substance to imbibe a liquid, there must first be some attraction between them. Imbibition occurs when a wetting fluid displaces a non-wetting fluid, the … WitrynaAbstract. Water is essential for the rehydration of seeds as the initial step towards germination. The amount of water taken up by an imbibing seed depends upon a number of factors (e.g. size, hydratability of contents, etc.) but in absolute terms it is quite small and often may not exceed 2–3 times the dry weight of the seed. chubb and corvel https://insegnedesign.com
