In the course of germinating plant seeds - if the deuterium (D) concentration in the germinating medium (water) is lower or higher than in natural water (150 ppm) - the length and mass of seedlings (coleoptil, epicotyl, root) proportionally decrease. The cause of the decrease owing to the changed D concentration is explained partly on energetic - partly on free radical basis and proved by measuring. In waters with lower or higher than natural D concentration the energy supply decreases while the free radical formation increases. Free radicals exert their influence by inactivating the bios substances (e.g. auxin) through oxidation. This seems to explain the mechanism of the ensuing changes.
