Salinity stress induced changes in onion genotypes: biochemical and physiological traits, ion homeostasis, and bulb formation.

ABSTRACT:

Background

Soil salinity disrupts several physiological, biochemical, and metabolic processes essential for onion growth and development.

Materials and methods

A pot experiment was conducted to examine the effect of salinity (0.12, 0.5, 0.85, 1.85, 3.55, and 5.0 dS m⁻¹) on plant growth, physiological traits, biochemical properties, ionic balance, and bulb formation of four onion genotypes grown in clay loam soils during the winter season at ICAR-DOGR, Pune.

Results

salinity levels at 0.5 and 0.85 dS m⁻¹ increased plant height, maintained leaf number, leaf area index, and dry matter accumulation of Bhima Shakti and Bhima Red, leading to a slight increase in bulb yield (1.3% ;1.8% respectively) at 0.5 dS m⁻¹, while a decline in yield (2.1% ;2.2% respectively) was observ
