Morpho-anatomical differentiation of Suaeda maritima (L.) Dumort. 1827. (Chenopodiaceae) populations from inland and maritime saline area

Abstract

Morphological analysis of four populations of Suaeda maritima was undertaken in order to examine the variation between populations from inland and maritime saline area, as well as between the two subspecies. Variability and significance of morpho-anatomical differentiation were examined using principal component analysis (PCA), discriminant component analysis (DCA) and cluster analysis. Plants of each population exhibited halomorphic and xeromorphic characteristics. The results of PCA and DCA showed that S. maritima subsp. prostrata and S. maritima subsp. maritima could be clearly separated based on their quantitative anatomical characteristics. Based on our analysis, climate and the amount of salt and ions in the soil, are important factors that enhance the adaptive potential of S. maritima.

Heavy metal content in halophytic plants from inland and maritime saline areas

“…Other soil properties such as percentage of salinity and concentration of cations also affected metal uptake by halophytes. The influence of climatic conditions on salt concentration was explained in detail in our previous work [32]. In this study a positive correlation was found between the percentage of salt in the soil and almost all the investigated metals in underground and aboveground organs of H. portulacoides as well as in the roots of S. maritima.…”

Anatomical features and SCoT profiles provide new insight into phenotypic plasticity in the halophyte Suaeda maritima in Thailand

“…Differing color appearances in vegetative parts such as stems, leaves, and shoot, reflecting this heteromorphism have been reported in Suaeda species (Alghamdi 2012;Raju and Kumar 2016). The variations in color morph characters could be situational depending on the nutrient and water levels, temperature, age, and other ecological factors such as the spectral quality of shade treatments (Ihm et al 2004;Polić et al 2009;Alghamdi 2012;Aluri et al 2016;Raju and Kumar 2016).…”

“…It is an annual, typically autogamous species with small and inconspicuous flowers that have only been reported of the genus Suaeda for Thailand. However, its taxonomic identity is problematic since it displays variations due to diverse stressful saline habitats (Wetson et al 2008;Polić et al 2009;Wetson et al 2012). Currently, very little study has been conducted on phenotypic variations within and between local populations of the salttolerant S. maritima in Thailand, even though the effects on the variation of the salt-marsh plant may be a key driver of reproduction, establishment, and existence in unpredictable and stressful environments.…”

Anatomical Adaptations of Halophytes Within the Southern Pannonian Plain Region

“…In Salicornia, vessel diameter decreases only locally, and the vessel is equally wide on both sides of the constriction, which might be the consequence of axillary bud development. Suaeda maritima is a succulent saltmarsh euhalophytic species, tolerant to high levels of salinity, found in Europe on sea coasts and inland salines (Polic et al 2009). Its stem has single-layered epidermis.…”

“…Eco-anatomical investigations of halophytes of continental salines in the Pannonian part of Serbia began in the 1980s and have continued until the present day (Janjatovic et al 1989(Janjatovic et al , 1990(Janjatovic et al , 1991(Janjatovic et al , 1992(Janjatovic et al , 1995Kneževic et al 1996Kneževic et al , 1998Polic et al 2009;Milic et al 2011Milic et al , 2012Milic et al , 2013aZoric et al 2013). These investigations have provided valuable information on the floristic and vegetation composition of salines, based on detailed analyses from ecological perspective.…”
