“…In both seasons, the lowest values of leaves dry weight were obtained in the case of Giza 2 under 200 mM concentration which recorded 0.144 and 0.543g, respectively. These results are in line with those obtained by Carilloet al et al (2018)andRezende et al (2018) and they mentioned that, the depressive effect of salinity on plant growth may be due to the increase in the osmotic potential of the soil which caused in a reduction in the availability of water to the plant.…”

Quinoa is a halophytic species emerging as a potential new crop in many regions of the world because of the nutritional composition of their seeds. This study has been carried out at the Faculty of Environmental Agricultural Science, Arish University, Egypt during the two successive growing seasons 2016/2017 and 2017/2018. The experiment has been done at the shad net house of the experimental crop farm using quinoa seedlings (one month old), which grow in pots. Seedlings have been irrigated every two days using four treatments of irrigation water (control, 100, 150, 200 mM), where control was tap water 85 mM. It was observed that vegetative parameters of quinoa seedling were significantly decreased with increasing water salinity concentration .The highest value for each of plant height, root length, number of leaves, leaf dry weight, shoot dry weight, root dry weight, water relative content was obtained with low saline control, followed by 100, 150 and 200mM which gave the lowest values in this respect. Concerning growth analysis, the maximum value for each of leaf area duration, relative growth rate, crop growth rate and net assimilation rate was achieved by control, followed by the other respected studied concentration which gave the lowest values. The obtained results cleared that the concentration of nitrogen, phosphorus and potassium, pigments decreased in plant tissue with increasing water salinity concentration. However, sodium and proline concentrations increased in plant tissue with increasing salinity concentration. It worthy to note that there were significant differences between Giza1 and Giza2 in most studied parameters.

“…9-13). The total pigments, for example, decreased by about 8.22 and 13.0% at 200 & 300 mM NaCl respectively comparing to control, the same result was observed in cultivars of rice as well as cape goosebelly regenerated in vitro grown in presence of NaCl (Rezende et al, 2018). The decrease in chlorophyll contents in salt-stressed plants can be attributed to insufficiency of essential nutrients and inhibition of nutrients uptake (Srinieng, 2015).…”

Salt stress is one of several major abiotic stresses that affect plant growth and development, and there are many evidences that silicon can ameliorate the injuries caused by high salinity. This study presents the results of an assay concerning: (1) the effect of NaCl induced salt stress in barely plant (cultivar Giza 123) and (2) the possible mitigating effect of silicon in saline conditions. In these study, different concentrations of NaCl (200 & 300 mM) used singly or in combination with silicon (0.5&1.0 mM potassium silicate). Morphological characters of shoot and roots, membrane stability index, relative water content, sodium, potassium, silica, photosynthetic pigments content and some antioxidant enzymes, as well as leaf electron microscope were evaluated. The results showed that, all parameters analyzed decreased except antioxidant enzymes and sodium content were drastically increased by increased salt levels. The supply of silicon (1mM) has successfully mitigated the effect of salinity at 300 mM NaCl. In conclusion, we affirmed that, salt stress is harmful for cape barley plants and the addition of silicon showed effective in mitigating the saline effects.

“…Indeed, excessive salt concentrations in the root zone impedes the regulation of the net uptake of essential ions or harmful ions, and an imbalance in either of them causes a reductions in leaf chlorophyll concentration and photosynthetic efficiency [ 78 , 79 , 80 ]. Furthermore, overproduction of ROS, including H 2 O 2 , O 2 − , and OH as a result of salinity stress contributes to corrupted chlorophyll levels and pigment degradation, which is considered as an oxidative harm marker [ 20 , 81 , 82 , 83 ].…”

Field-based trials and genotype evaluation until yielding stage are two important steps in improving the salt tolerance of crop genotypes and identifying what parameters can be strong candidates for the better understanding of salt tolerance mechanisms in different genotypes. In this study, the salt tolerance of 18 bread wheat genotypes was evaluated under natural saline field conditions and at three saline irrigation levels (5.25, 8.35, and 11.12 dS m−1) extracted from wells. Multidimensional evaluation for salt tolerance of these genotypes was done using a set of agronomic and physio-biochemical attributes. Based on yield index under three salinity levels, the genotypes were classified into four groups ranging from salt-tolerant to salt-sensitive genotypes. The salt-tolerant genotypes exhibited values of total chlorophyll, gas exchange (net photosynthetic rate, transpiration rate, and stomatal conductance), water relation (relative water content and membrane stability index), nonenzymatic osmolytes (soluble sugar, free proline, and ascorbic acid), antioxidant enzyme activities (superoxide dismutase, catalase, and peroxidase), K+ content, and K+/Na+ ratio that were greater than those of salt-sensitive genotypes. Additionally, the salt-tolerant genotypes consistently exhibited good control of Na+ and Cl− levels and maintained lower contents of malondialdehyde and electrolyte leakage under high salinity level, compared with the salt-sensitive genotypes. Several physio-biochemical parameters showed highly positive associations with grain yield and its components, whereas negative association was observed in other parameters. Accordingly, these physio-biochemical parameters can be used as individual or complementary screening criteria for evaluating salt tolerance and improvement of bread wheat genotypes under natural saline field conditions.
