About participation of oxidoreductases in mechanisms of dormancy and germination in wheat corn

The authors estimated the activity of glucose-6-phosphate dehydrogenase, isocitrate dehydrogenase (NAD+), alcohol dehydrogenase and peroxidase in wheat corn and seedlings (Triticum aestivum L.). It was established, that these dehydrogenases are required for the retention of seed viability and for the initiation of processes, related with seed germination. The peroxidase, catalyzing the reactions with participation of oxygen and hydrogen peroxide, regulates the content of these substances in dormant corn. Considerable increase of peroxidase activity during germination of corn seeds can suggest about participation of this enzyme in activation of starting mechanism of respiration.
