Phenotypic plasticity of four Chenopodiaceae species with contrasting saline-sodic tolerance in response to increased salinity-sodicity.

ABSTRACT: It is unknown whether phenotypic plasticity in fitness-related traits is associated with salinity-sodicity tolerance. This study compared growth and allocation phenotypic plasticity in two species with low salinity-sodicity tolerance (Chenopodium acuminatum and C. stenophyllum) and two species with high salinity-sodicity tolerance (Suaeda glauca and S. salsa) in a pot experiment in the Songnen grassland, China. While the species with low tolerance had higher growth and allocation plasticity than the highly tolerant species, the highly tolerant species only adjusted their growth traits and maintained higher fitness (e.g., plant height and total biomass) in response to increased soil salinity-sodicity, with low biomass allocation plasticity. Most plasticity is "ap
