Seed germination is a complex physiological process through which the embryo is passing from the latent to active life. The germination process starts with water uptake by imbibition of seeds, the water been necessary for enzyme system activation in view to breakdown the complex substances stored within the seed, as well as for translocation and use by the embryo of the substances resulted from the enzyme activity. After this first germination stage, the germination process continues with embryo growth, and finishes with the radicle emergency from the seed, during these stages the water continuing to be uptake by the seed after a specific curve. The main aim of the present study is to determine the water uptake by different cereal seeds (wheat, durum wheat, triticale, barley, and maize) during the germination process, this been expressed through the seed water content and water absorbed by seeds reported to their dry matter content in different germination stages. Also the study is aiming to find out the time needed for the germination process, as well as how the process of water uptake is going on from the begging up to the end of the germination process.
