Other claims from this paper (10)
- Intervention effect Lower NaCl treatments did not affect relative growth rate.
- Intervention effect Primary root length increased at all NaCl concentrations.
- Intervention effect Total lateral root length increased at 50 mm NaCl.
- Intervention effect Total lateral root length was unaffected at 100 mm NaCl.
- Intervention effect Total lateral root length decreased at 200 mm NaCl.
- Intervention effect At 50 and 100 mm NaCl, the numbers of first, second and third order lateral roots fell.
- Intervention effect Third order laterals did not form at 200 mm NaCl.
- Intervention effect Mean lateral root length increased at all NaCl concentrations and was highest at 200 mm.
- Mechanism Authors attribute the total lateral root length increase at 50 and 100 mm to greater length growth.
- Mechanism Authors attribute the total lateral root length decrease at 200 mm to inhibited primordia or apical meristem activation.
