Alcohol dehydrogenase and glucose-6-phosphate dehydrogenase activity in leaves and roots of barley (Hordeum vulgare) seedlings under combined action of low temperature and excessive humidity
It is shown that under combined action of low temperature and excessive humidity there are changes in respiratory exchange by means of intensification of glycolysis and pentose phosphate pathway of glucose oxidation through activation of key enzymes - alcohol dehydrogenase and glucose-6-phosphate dehydrogenase respectively. Thus increased alcohol dehydrogenase activity in roots and leaves is associated mainly with excessive humidity effect. Increased glucose-6-phosphate dehydrogenase activity in roots is due to low temperature action and in leaves is caused by excessive humidity effect.
