Abstract

Meloidogyne incognita beside being pathogenic to green gram, was found to interfere with the functioning of nodules and normal root biochemistry. Higher concentration of amino acids (except L-tryptophan) and total sugar were observed in nematode, rhizobium and both rhizobium and nematode inoculated roots. The chlorophyll content of leaves reduced only in nematode inoculated plants. Leghaemoglobin and nitrogenase activities were also reduced in nematode infected nodules.
