ABSTRACT
The adsorption of water on the surface of hydrophylls is known as hydration or imbibition. Besides, this process is the function of the viability of seeds. The imbibition of water in a dry seed induces a sequence of chemical reactions which induce the germination and subsequent seedling development. The germination of the seeds of wild plants is frequently limited by this or other internal factors or only for the absence of moisture and or hot. Carefully weigh in analytical balance exactly 10.0 g of seeds of the lot assigned and place the seeds in one beaker. The layers cover the embryon may interfere with the entry of water and oxygen or both, and may impede the emergence of radicle acting as mechanical barriers. In other seeds, it seems that it impedes the escape of inhibitors of embryo or these themselves contain inhibitors of germination.
