Theme III. Agricultural use of peat and peatlands
Phenol oxidase has been found to be one of the scarce enzymes capable of decomposing phenolic compounds. Different types of peat and commercial substrates for rooting of cuttings and various concentration of IAA (200 μg kg-1, 300 μg kg-1, 400 μg kg-1) were tested in this experimental trial. Following commercial growing media was used: “Klasmann Steck Medium” (Kronen Klasmann) for rooting cuttings. Phenol oxidase activity was determined in commercial growing media. The obtained results revealed the impact of the IAA content on phenol oxidase activity. However, an increase phenol oxidase activity with IAA content of 200 μg kg-1, 300 μg kg-1 and 400 μg kg-1 was observed. In control combination (without IAA) lower the phenol oxidase activity was confirmed.
