Abstract

The effect of two N forms ( NH+4 and NO-3) and NaCl on accumulation of some essential mineral nutrients was examined in canola (Brassica napus L.) cv. ‘SLM046’. Eight-day- ld plants of were subjected for 21 day to Hoagland’s nutrient solution containing 10 mM NH+4 and NO-3 and salinized with 0, 50, 100 and 150 mm NaCl. N form and addition of NaCl to the growth had no significant effect on total N. However, root N of NH+4 supplied plants decreased significantly with increase in NaCl concentration, whereas that of NO3- supplied plants remained unaffected. Salinity of the rooting also did not show any significant effect on Na+ concentration of leaves or roots of plants subjected to two different forms of nitrogen. NH+4 treated plants generally had greater concentration of Cl- in leaves and roots and lower K+ content in leaves than NO3- supplied plants. Ca2+ concentration of leaves and roots concentration of leaves decreased in NH+4- supplied plants due to NaCl, but they remained unaffected in NO3- treated plants.
