Salinity tolerance and growth response of redroot pigweed <i>(Amaranthus retroflexus</i> L.): a comprehensive evaluation.

ABSTRACT: Amaranths (Amaranthus L.) are multi-use crop species known for their nutritional quality and tolerance to salinity stress. As soil salinity has become an increasing issue globally, we conducted a study to test the salinity tolerance of one cultivar of Amaranthus retroflexus L. (Redroot pigweed). The plants were grown for 30 days in pot culture conditions at different salinity levels: non-saline, slightly saline, moderately saline, highly saline, and extremely saline (using two different rates: extreme₁ and extreme₂ . We assessed various growth parameters including plant height, stem diameter, root, stem and leaves fresh (FW) and dry weight (DW), water content (WC), photosynthesis rate (P_n), transpiration rate (E), water use effic
