“…Higher proline and total soluble sugar content accumulation was also observed in other plants exposed to salt stress 37,38 . According to Muchate et al 39 , this might be associated with higher energy consumption for osmolyte synthesis, which, could lead to growth decline.…”

Salt tolerance is a much-needed potential in cereal crops. To date, numerous research protocols have focused on establishing selection programs to increase tolerance and productivity of crops in salt-stressed areas. In this study, we aimed to induce callus from endosperm-supported mature embryos of five common wheat varieties (Nassim, Wissam, Wafia, Rajae, and Tigre) subject directly to various increasing NaCl concentrations (0–9 g/L) under in vitro culture process. We chose callus growth, organic solutes accumulation, and ion content as main traits to evaluate the impact of salinity on stressed calli. Our findings indicate that the accentuated salinity pressure leads to a substantial elevation of Cl−, Na+, proline and soluble carbohydrates content, along with a reduction in callus growth, potassium accumulation, and K+/Na+ ratio. Yet, the performance under salt stress was significantly dependent on the varietal effect. At the highest concentration, the marked values of these solutes (12.06 µmol/g FM of proline; 43 µmol/g FM of Total soluble sugar; 31.15 mg/ g DM Na+; 12.82 mg/g DM of Cl−, 12.61 mg/g DM of K+ and 0.40 K+/Na+) were respectively recorded by Rajae. Principal component analysis (PCA) first classified Rajae as the most tolerant followed by wafia as tolerant, while Wissam and Tigre were ranked as sensitive. Whereas, the variety Nassim showed a moderate tolerance. Besides the K+/Na + Ratio and salinity tolerance index (STI), the PCA analysis has shown that all the studied physiological criteria seem worthwhile for better discrimination of the varieties tested according to their reaction to salinity.

Salinity is a serious problem in the cultivation of ornamental plants. Chrysanthemum (Chrysanthemum × grandiflorum) ‘Palisade White’ was evaluated in order to examine its responses to long-term salt stress. Plants were grown in substrate supplemented with NaCl doses (g dm -3 of substrate) 0, 0.44, 0.96, 1.47, 1.98, 2.48, 2.99. The initial electrical conductivity (EC) of the substrates was 0.3, 0.9, 1.4, 1.9, 2.6, 3.1, 3.9 dS·m -1, respectively. Plant growth, relative water content (RWC), Na, Cl, K, N and P concentrations, membrane injury (MI), chlorophyll and proline levels, as well as on gas exchange parameters in leaves of chrysanthemum were determined. A dose-dependent significant reduction of growth and minor decrease of leaf RWC were observed. Foliar Na and Cl concentrations increased with the highest NaCl dose up to 6-fold. However, the concentration of K increased by about 14%, N by about 5% but P decreased by about 23%. Membrane injury was rather low (11%) even at the highest NaCl dose. Statistically significant decreases of stomatal conductance (20%), transpiration rate (32%) and photosynthesis (25%) were already observed at the lowest NaCl dose and about 40% decrease of all these parameters with the highest dose. A significant reduction in the intercellular CO2 concentration occurred at the lower NaCl doses and no changes with the highest dose. These results show that in plants grown with the highest NaCl dose, non-stomatal limitation of photosynthesis may occur. According to Maas and Hoffman tolerance assessment (1977) chrysanthemum ‘Palisade White’ may be considered as moderately sensitive to salt stress in term of growth inhibition. However, it is able to cope with long-term salt stress without any signs of damage, such as chlorophyll depletion, leaf browning or necrotic spots probably due to maintenance of K homeostasis and proline accumulation, which alleviate the toxic effect of chloride.
