The tale of two Ions Na⁺ and Cl^-: unraveling onion plant responses to varying salt treatments.

ABSTRACT:

Background

Exploring the adaptive responses of onions (Allium cepa L.) to salinity reveals a critical challenge for this salt-sensitive crop. While previous studies have concentrated on the effects of sodium (Na⁺), this research highlights the substantial yet less-explored impact of chloride (Cl^-) accumulation. Two onion varieties were subjected to treatments with different sodium and chloride containing salts to observe early metabolic responses without causing toxicity.

Results

The initial effects of salinity on onions showed increased concentrations of both ions, with Cl^- having a more pronounced impact on metabolic profiles than Na⁺. Onions initially adapt to salinity by first altering their organic acid concentrations, which a
