Randomized trial assessed salt-removal potential of preconditioned Casuarina glauca in saline soils, indicating its effectiveness for land rehabilitation.
Key Points
This study evaluates the phytodesalination potential of Casuarina glauca, focusing on the impact of preconditioning in saline conditions.
Cultivated Casuarina glauca saplings for 12 months in saline soils.
Compared preconditioned versus non-preconditioned plant performance.
Analyzed biomass, soil conditions, and ion uptake (sodium and chloride).
Preconditioned plants showed enhanced biomass and improved soil conditions compared to non-preconditioned plants.
C. glauca demonstrated a high bioconcentration factor for sodium and chloride, with low sodium translocation and high chloride translocation.
Chloride accumulation in shoots did not negatively impact biomass, indicating effective chloride compartmentalization.
