DENDROLOGY

Detailed explanation-1: -During the beginning stage of germination, the seeds take up water rapidly and this results in swelling and softening of the seed coat at an optimum temperature. This stage is referred to as Imbibition.

Detailed explanation-2: -Imbibition in Plants Imbibition causes swelling of the seed which leads to the rupture of the seed coat or testa. Imbibition forms the first step in seed germination. Imbibition aids in the flow of water to the ovules, which mature into seeds. Imbibition is required in the early stages of root water absorption.

Detailed explanation-3: -Imbibition is a type of diffusion where the water is absorbed by the solid particles called colloids, causing an enormous increase in volume. The solution is not formed in the process. In other words, water absorption by colloids is known as imbibition.
