Abstract: | The growth and nodulation ofTrifolium alexandrinum were compared at six levels (0 - 1.2 % NaCl) of salinity. Dry mass of shoots and roots, 14 and 20 weeks after the commencement of salinity treatment, increased at low levels of salinity (0.1 - 0.2 % NaCl) but decreased with higher NaCl concentrations (0.4 - 1.2 %). Nodulation occurred at NaCl concentrations up to 0.8 %. Nodule mass decreased with increasing salinity levels. The nodule size remained unaffected at NaCl concentrations up to 0.4 % but was reduced at higher concentrations. |
