Abstract: he redox state of cytochrome c_ oxidase during in situ respiration of seventeen promising sugarcane cultivars was monitored by examining the reaction of this enzyme with carbon monoxide, as expressed by production of nitrite during aerobic assay of in_ vivo nitrate reductase. All the seventeen sugarcane cultivars thus tested were found to be completely sensitive to CO, indicating thereby that the cytochrome a-, in these cultivars was in a highly reduced state during the steady state respiration. The salt stress induced by two sodium salts, viz., NaCl, Na2S04 and the equimolar mixture of NaCl and Na2S04 decreased the nitrate reductase activity, more pronounced decrease being observed by Na2So4 than either by NaCl alone x iv ABSTRACT...(CONTD.0.) or its combination with Na2S04,The salt stress also decreased the reducing and non-reducing sugars and chlorophyll and potassium content, but increased the proline content of sugarcane leaves„ Amongst the four sugarcane cultivars studied, Co-7527 had the highest nitrate reductase activity under stressed conditions, and could retain maximum in vivo NR activity under the stressed condition,. On the basis of increase in accumulation of proline in leaves and retention of chlorophyll content, the cultivar Co-419 appeared to be more salt tolerant than the other cultivars of sugarcaneo The increased response of these cultivars to carbon monoxide due to salt stress could possibly be due to decreased mitochondrial respiration.
