Effect of salt stress on nitrate reductase activity in some leguminous crops



Effect of salt stress on nitrate reductase activity in some leguminous crops



Indian Journal of Plant Physiology 37(3): 185-187



The effects of increasing levels of NaCl and Na-2 CO-3 (0, 4, 8 and 12 dSm-1) on nitrate reductase activities (NRA) in Lentil (Lens esculentum L.), Chickpea (Cicer arietinum L.) and Pea (Pisum sativum L.) were studied. Salt stress caused a marked reduction in NRA in both root and shoot parts. NRA in shoot was inhibited to a greater extent than in the roots and Na-2 CO-3 inhibited more than NaCl. On the other hand, a foliar spray with triacontanol (CH-3 (CH-2)-28 CH-2 OH) in nanomolar concentrations stimulated NRA in both parts of the plants. This enhancement was attributed to the capacity of triacontanol to induce enzyme activity.
