“…Saline conditions can increase succulence as was earlier observed by Debez et al (2006), Boughalleb et al (2009) and Akcin et al (2015) in halophyte plants. Increased succulence may aid in storing additional water by increased vacuolar volume and better survival at higher salt levels (Hameed et al 2010).…”

A salt-tolerant population of Salicornia freitagii Yaprak and Yurdakulol (naturally adapted) from saline soils of Bahşili village, Sungurlu, Ç orum, Turkey, was evaluated for root and succulent stem modifications. Salttolerant populations from low (2.3 dS m-1), medium (20.7 dS m-1) and highly (46.3 dS m-1) saline soils were collected for comparisons. Decreased parenchyma in roots is critical for enhancing water loss. However, the thickness of parenchyma in roots of S. freitagii collected from the edge of the stream was not more affected by the increase in salinity levels. Stem anatomical characters as thickness, length and width of water-storing tissue significantly increased in highly saline environments. The thickness of xylem and the diameter of the vessels decreased at higher salinity. There was an increase in the diameter of pith in stem with increasing salt levels. Additionally, it was observed that stomatal index was considerably reduced under high salinity. Our results report root and stem anatomical features of S. freitagii resulting from adaptation to salinity stress.

“…Halophytes develop specific morpho-anatomical and physiological features and modifications which help them survive saline conditions and minimize negative effects of salt stress (Waisel 1972;Akcin et al 2015). The most obvious adaptations manifest in the organization of plant body as a whole, as well as in the morphology of vegetative organs.…”

“…In general, anatomical adaptations to salt stress include increased cell volume due to which leaf thickness increases, whereas vessel diameter decreases (Akcin et al 2015(Akcin et al , 2017Rancic et al 2019). Formation of narrower vessels improves water-use capacity and reduces risk of xylem embolism and cavitation in saline habitats (Polle and Chen 2015).…”

Halophytes have developed different types of adaptive strategies, which enable them to survive in salt stress and physiological drought conditions common to saline habitats. Anatomical adaptations at cellular, tissue, or organ level play a crucial role in the development of a wide range of salt tolerance. Succulence is one of the most prevalent adaptations, along with an increased cell volume, welldeveloped water storage parenchyma, Kranz leaf anatomy, strong lignification, successive cambia formation, formation of salt secretory structures, tracheoidioblasts and bulliform cells. Halophytes found in dry saline habitats tend to develop xerohalomorphous anatomical adaptations, which affect mostly epidermal, vascular, and mechanical tissue. The present investigation focuses on the diverse mechanisms employed by halophytes inhabiting continental halobiomes of the southern Pannonian plain region.

Potential of herbaceous vegetation as animal feed in semi‐arid Mediterranean saline environments: The case for Tunisia

With the depletion in arable land due to climate change, the use of naturally salt‐tolerant species to provide forage resources in arid and saline environments has become an emerging strategy. This study surveyed and determined the nutritive value of selected Tunisian vegetative species for use in Mediterranean saline environments. Eighteen wild species were analyzed for their nutrient contents and antinutritional factors. Chenopodiaceae accumulated more NaCl than Poaceae. Arthrocnemum indicum had the highest crude protein (CP) content, and Stipa roterta had the lowest. Poaceae had the highest fiber constituents (neutral and acid) and the lowest oxalate contents. Daily net gas production (GP) in the Chenopodiaceae and Poaceae ranged from 9.5 to 14.5 and from 13.8 to 37.9 ml per 0.2 mg dry matter (DM), respectively. Total phenol content and organic matter digestibility were species dependent. The metabolizable energy (ME) in the tested species ranged from 4.6 to 9.4 MJ kg−1 DM, with Catapodium rigidum and Arthrocnemum indicum having the lowest and highest ME values, respectively. In crux, Chenopodiaceae had the highest NaCl, CP, ME, and oxalate contents but had the lowest fiber and net GP. Sodium chloride content was positively correlated with CP and oxalate and negatively correlated with net GP. In arid and saline environments, where high salinity prevails and fodder resources are scarce, salt‐tolerant plants such as Suaeda fruticosa, Arthrocnemum indicum, and Halocnemum strobilaceum could be included in ruminant feeding calendars.
