Abstract
By nitrogenase activity and diazotroph number determination, in the rh izosphere of several genetically divergent wheat genotypes, potential possibility of elementary nitrogen incorporation from the atmosphere b y Triticum aestivum L. was investigated. In most studied cultivars, a positive correlation was found between nitrogenase activity and diazot roph number. The highest nitrogenase activity was found in cultivar Sk opljanka (178.00 nmol C2H4/g Of root) after 48h of reduction, in which number of diazotrophs was also the highest (955.0 x 10(4)).
