Introduction: The relevance of the investigated problem lies in the problem of improving the condition of degraded and saline soils, on which plants of representatives of Chenopodeaceae and Tamaricaceae families grow, adapted to life in such conditions. In this regard, the aim of this article is to study the ecology, salinity accumulation and salt excretion of Climacoptera lanata and Tamarix hispida, determining the adaptation abilities of Climacoptera lanata and Tamarix hispida in Kyzylkum Desert conditions. Material and Methods: The main methods that were used to achieve the goal: generally accepted methods of soil determination – spectrophotometric, potentiometric, manometric. Results and Discussion: The main results that were achieved in this study: salt balance of halophytes was revealed on the example of C. lanata and T. hispida species, groups on plant resistance, on the quality of salt accumulator and salt extractor, on dry residue (2-3.4; Cl- 0.1-0.3, SO42- 1.5-1.9%) were identified, saline soils were determined. Leaf respiration intensity ranged from 111-323 mm3 O2. Bioecological features of C. lanata and T. hispida, as well as chemical composition of soil and water in Central Kyzylkum and mineral composition of biomass of the studied plants, were revealed. Conclusion: The main ecological problems in the conditions of Uzbekistan were determined. The practical significance of the study is that methods of adaptation of Climacoptera and Tamarix species to saline soils in areas with low water level (2-3.5 m) can be used for similar biotypes in order to reduce damage from soil salinity.

“…The cultivation of halophilic plants holds great potential for advancing biosaline agriculture, as highlighted by Grigore and Vicente [ 11 ]. The increasing prevalence of stress conditions such as drought, salinity, and high temperatures has led to a growing interest in utilizing wild halophytes as crops.…”

(1) Background: This study provides novel insights into the elemental content and biomineralization processes of two halophytic species of the genus Arthrocnemum Moq. (A. macrostachyum and A. meridionale). (2) Methods: Elemental content was analyzed using ICP-MS, while biominerals were detected through electron microscopy (SEM and TEM) and X-ray diffraction. (3) Results: The elemental content showed significant concentrations of macronutrients (sodium, potassium, magnesium, and calcium) and micronutrients, especially iron. Iron was consistently found as ferritin in A. macrostachyum chloroplasts. Notably, A. macrostachyum populations from the Center of the Iberian Peninsula exhibited exceptionally high magnesium content, with values that exceeded 40,000 mg/kg d.w. Succulent stems showed elemental content consistent with the minerals identified through X-ray diffraction analysis (halite, sylvite, natroxalate, and glushinskite). Seed analysis revealed elevated levels of macro- and micronutrients and the absence of heavy metals. Additionally, the presence of reduced sodium chloride crystals in the seed edges suggested a mechanism to mitigate potential sodium toxicity. (4) Conclusions: These findings highlight the potential of Arthrocnemum species as emerging edible halophytes with nutritional properties, particularly in Western European Mediterranean territories and North Africa. They offer promising prospects for biosaline agriculture and biotechnology applications.

“…One of the reasons is related to the desire to reduce plant production losses caused by environmental salinization, and an understanding of salt tolerance could help greatly. In this sense, salt-tolerant wild plant species are interesting models for studies aimed at uncovering plant salt adaptation mechanisms [ 1 , 2 ]. On the other hand, there is interest in studying the properties of salt-tolerant plants in relation to their possible practical uses [ 3 , 4 , 5 , 6 , 7 ].…”

Mesembryanthemum crystallinum L. is an obligatory halophyte species showing optimum growth at elevated soil salinity levels, but the ionic requirements for growth stimulation are not known. The aim of the present study was to compare the effects of sodium, potassium and calcium in the form of chloride and nitrate salts on the growth, physiological performance, ion accumulation and mineral nutrition of M. crystallinum plants in controlled conditions. In a paradoxical way, while sodium and potassium had comparable stimulative effect on plant growth, the effect of calcium was strongly negative even at a relatively low concentration, eventually leading to plant death. Moreover, the effect of Ca nitrate was less negative in comparison to that of Ca chloride, but K in the form of nitrate had some negative effects. There were three components of the stimulation of biomass accumulation by NaCl and KCl salinity in M. crsytallinum: the increase in tissue water content, increase in ion accumulation, and growth activation. As optimum growth was in a salinity range from 20 to 100 mM, the increase in the dry biomass of plants at a moderate (200 mM) and high (400 mM) salinity in comparison to control plants was mostly due to ion accumulation. Among physiological indicators, changes in leaf chlorophyll concentration appeared relatively late, but the chlorophyll a fluorescence parameter, Performance Index Total, was the most sensitive to the effect of salts. In conclusion, both sodium and potassium in the form of chloride salts are efficient in promoting the optimum growth of M. crystallinum plants. However, mechanisms leading to the negative effect of calcium on plants need to be assessed further.
