Abstract
Barley genotypes grown in nutrient solution under P nutrient stress and sterile conditions were compared in activity of root-associated and root-released extracellular phytase. The activity of root-associated phytase of all genotypes was about 10 times higher than that of root-released phytase and the genotypes performed differently with regard to the activity of the enzymes. The winter barley genotype, Marinka had the highest activity of root-associated extracellular phytase which differed significantly from Alexis and Senate, but not from Regatta. Alexis showed the lowest activity of root-released extracellular phytase which differed significantly from those of Marinka and Regatta, but not from Senate. Generally, there was a significant correlation between the activity of root-associated and released extracellular phytase.
