Abstract

The majority of the plants secrete their enzymes in the soil, where they can decompose various organic compounds. Extra cellular plant enzymes can be effective against a number of contaminants. To estimate the plants, their enzymes and micro-organism effect on hexadecane content in the soil, the sterile soil samples was amended with 0.5 % hexadecane and sowed with accordingly prepared rye seeds. Till increasing the quantity of micro-organisms and the formation of rye seedlings, hexadecane content remained practically unchanging in all samples. After 21 days hexadecane content in the soil with rye seedlings was about 5 % of the contributed content. The intrinsic soil processes through 21 days to shrank the hexadecane content in the soil without rye seedlings up to 17 %. Oxidases, catalases and peroxidases were detected in rye biomass during all test period. As shown by the results, polyphenoloxydases were detected only in root biomass, the early germs of germination and roots formation stages.
