NITRATE RED UCTASE ACTIVITY IN DALBERGIA SISSOO AND EUCALYPTUS HYBRID SEEDLINGS UNDER THE INFLUENCE OF ARBUSCULAR MYCORRHIZAL PHOSPHORUS AND NICKELManoj Tiwari
Toxicity of nickel on nitrate reductase activity of ar"buscular mycorrhiza inoculated Dalbergia sissoo and Eucalyptus hybrid seedlings was studied at three leveWeach of nickel (0.5, 5.0 and 50 pM) and phosphorus (0.5, 1.0 and 2.0 mM) in sand culture. E. hybrid had Higher nitrate reductase activity than D. sissoo, with almost equal level of reduction in both species by nickel. Reduction in nitrate reductase activity by phosphorus was observed only in D. sissoo. Arbuscular mycorrhizal inoculation did not show any significant effect on nitrate reductase activity of both spek:ies, but interacted significantly with phosphorus and increased nitrate reductase activity in both species.
