Abstract

Abstract Suaeda salsa serves as an excellent species for environmental remediation in saline-alkali areas. However, its ecological differentiation in different habitats is not clear. Therefore, plant samples of S. salsa from two main habitats in northern China, including populations of saltmarshes and inland were collected, and their differences in external morphology, gene and chemical composition were comprehensively compared. The results showed 1) the basic composition of various organs of S. salsa plants in two habitats was consistent, but there were certain differences in height, color, size, etc. 2) 102 psbA-trnH sequences of S. salsa under different habitats belonged to two distinct haplotypes, with a high level of intraspecific genetic variation. The NJ phylogenetic tree analysis revealed the psbA-trnH sequence successfully distinguished 105 samples of S. salsa from two different habitats. 3) A total of 699 differential metabolites were detected in the two different habitats of S. salsa. The results showed that S. salsa populations were morphologically, genetically and chemically differentiated in different habitats, but there was no substantial difference in the characteristics of reproductive organs. Based on the above analysis, we concluded that S. salsa produced different ecotypes at morphological, genetic and chemical levels to adapt to different habitats.
