EFFECT OF SINGLE AND CONCOMITANT INOCULATIONS OF HETERODERA CAJANI AND FUSARIUM SOLANI ON TRE ACTIVITIES OF NITRATE REDUCTASE AND GLUTAMINE SYNTRETASE IN COWPEA

K. S. Varaprasad, P. A. Kumar

Abstract


Two hundred juveniles of Heterodera cajani and 2 g of Fusarium solani mycelial pieces in single inoculations significantly reduced nitrate reductase and glutamine synthetase activity in cowpea cv. Pusa Dophasli, 70 days after planting in a pot experiment. However, concomitant inoculations of nematode and fungus mitigated their individual effects on enzymes activity, which is also evident tram the reduction in nematode populations in presence of the fungus.
