Other claims from this paper (9)
- Observation Leymus arenarius tolerated sodium salts.
- Intervention effect Both salts reduced root biomass.
- Intervention effect Nitrate increased LA2 leaf number and biomass.
- Intervention effect Chloride decreased tiller and leaf sheath biomass.
- Intervention effect Salinity increased water content in leaf blades, sheaths and roots, most in LA2.
- Intervention effect Photosynthesis decreased at high salinity, particularly in LA2.
- Observation Nitrate-treated leaf Na+ reached 30 g kg−1.
- Observation Nitrate-treated root Na+ reached 20 g kg−1.
- Intervention effect Chloride-treated leaf and root accumulation was significantly lower, about 10 g kg−1.
