Response of saline water irrigation on Rangpur lime seedlings

The effect of saline water on nine Rangpur lime strains was evaluated in glasshouse conditions. The salinity ranged from 0.8 dSm⁻¹ (control), 1.5, 3.0 and 4.5 dSm⁻¹. The strains of Rangpur lime seedlings could survive salinity of 1.5 dSm⁻¹ but at 3.0 and 4.5 dSm⁻¹ mortality was observed. Shrirampur performance in both the salinity levels of 3.0 and 4.5 dSm⁻¹ was the same, while MO had the lowest mortality of 3.0 dSm⁻¹ and it increased at 4.5 dSm⁻¹. At all the salinity levels, Shrirampur and MO were the best chloride excluder because of their low chloride content in leaf and growth nature. RLL-2 and RLF had the lowest uptake of sodium in leaves followed by Shrirampur and MO.
