ABSTRACT

Soil micrganisms represent one of the largest reservoirs of biodiversity in the world. Soil microorganisms are very important as almost every chemical transformation taking place in soil involves their active contributions. The study of soil dynamics in presence of phytotoxic agents is of great importance because of the role that microorganisms have in modifying the phytotoxic compounds and consequently affecting their biological properties. Possible biotransformation developed by soil microorganisms could yield compounds with modified biological properties. The aim of the present work is to study microbial respiration in soil cultivated with different varieties of Triticum aestivum L. by measuring the emission of carbon dioxide (CO2), and by correlating the results to the ability of the soil to degrade allelochemicals and to release CO2.


Keywords: Benzoxazinones, degradation, CO2 emission, microflora, allelopathy.
