Other claims from this paper (9)
- Observation Salinity-induced growth reduction differed substantially among accessions.
- Observation Salt-tolerant accessions controlled gas exchange better and had higher tissue tolerance.
- Observation Salt-tolerant accessions had higher tissue tolerance.
- Observation Salt-tolerant accessions retained higher potassium content despite higher leaf sodium accumulation.
- Observation Salt-tolerant accessions accumulated higher sodium in leaves.
- Observation Wild rice maintained lower and steadier xylem sodium content over three weeks.
- Mechanism Wild rice's sodium profile suggests better control of xylem loading and shoot delivery with efficient vacuolar sequestration.
- Observation Sensitive genotypes avoided initial sodium loading but failed long term and had higher sap sodium.
- Mechanism Wild rice genotypes rely on tissue tolerance and sodium-mediated rapid osmotic adjustment.
