“…Application of Ca 2+ was able to reverse the effects of salt stress on sorghum seed germination especially at low concentrations (5 mM Ca 2+ ). Similarly, Ca 2+ also improved seed germination of Festuca ovina L. [ 24 ], Phragmites karka [ 39 ], Triticum aestivum [ 40 ], Urochondra setulosa [ 41 ], Pisum sativum [ 42 ], Solanum lycopersicon [ 43 , 44 ], and Vigna radiata [ 45 ].…”

Salinity is a major constraint limiting plant growth and productivity worldwide. Thus, understanding the mechanism underlying plant stress response is of importance to developing new approaches that will increase salt tolerance in crops. This study reports the effects of salt stress on Sorghum bicolor during germination and the role of calcium (Ca2+) to ameliorate some of the effects of salt. To this end, sorghum seeds were germinated in the presence and absence of different NaCl (200 and 300 mM) and Ca2+ (5, 15, or 35 mM) concentrations. Salt stress delayed germination, reduced growth, increased proline, and hydrogen peroxide (H2O2) contents. Salt also induced the expression of key antioxidant (ascorbate peroxidase and catalase) and the Salt Overlay Sensitive1 genes, whereas in the presence of Ca2+ their expression was reduced except for the vacuolar Na+/H+ exchanger antiporter2 gene, which increased by 65-fold compared to the control. Ca2+ reversed the salt-induced delayed germination and promoted seedling growth, which was concomitant with reduced H2O2 and Na+/K+ ratio, indicating a protective effect. Ca2+ also effectively protected the sorghum epidermis and xylem layers from severe damage caused by salt stress. Taken together, our findings suggest that sorghum on its own responds to high salt stress through modulation of osmoprotectants and regulation of stress-responsive genes. Finally, 5 mM exogenously applied Ca2+ was most effective in enhancing salt stress tolerance by counteracting oxidative stress and improving Na+/K+ ratio, which in turn improved germination efficiency and root growth in seedlings stressed by high NaCl.

“…Salinity irrevocably affects plant length, dry weight, and growth of tomato plants. Salinity also reduced the fresh and dry shoot and root weight of tomato [ 80 , 81 ]. The reduction of dry weights due to increased salinity may be a result of a combination of osmotic and specific ion effects of Cl and Na [ 82 ].…”

Population growth and food necessity envisaged the dire need for supplementation to a larger community balance in food production. With the advent of the green revolution, agriculture witnessed the insurrection of horticultural fruit crops and field crops in enormous modes. Nevertheless, chemical fertilizer usage foresees soil pollution and fertility loss. Utilization of biocontrol agents and plant growth promotion by microbial colonization enrooted significant restoration benefits. Constant reliability for healthy foods has been emancipated across the globe stressing high nutritive contents among indigenous field crops like tomato (Solanum lycopersicum). However, stress tolerance mechanisms and efficient abatement require deeper insights. The applicability of arbuscular mycorrhizal fungi (AMF) poses as an ultimate strategy to minimize the deleterious consequences of abiotic stress such as salt, drought, temperature and heavy metal stress sustainably. The rational modality employing the application of AMF is one of significant efforts to lessen cell damages under abiotic stress. The novelty of the compilation can be redressed to cohesive literature for combating stress. The literature review will provide agricultural scientists worldwide in providing a rational approach that can have possible implications in not only tomato but also other vegetable crops.

“…Recent studies have shown that calcium added to the saline solution was significantly improved plant species affected by high salinity (Levent Tuna et al, 2007;Tanveer et al, 2020). The aim of this study was to determine the negative effect of salt concentrations in the cultivation of ornamental cabbage in greenhouse conditions, and as a solution to salt stress, it was determined what change in direction of some stress parameters by applying of different concentrations of calcium nitrate.…”

Ornamental plants are used to improve the aestheticquality of urban and rural landscapes, recreational areas, interiorscapes and commercial sites. Any negative effects of salts on ornamental plant growth have to be taken into consideration mainly for their negative influences on aesthetic value of ornamental plants. The research was conducted to determine the effects of different concentrations of calcium nitrate on some stress parameters (i.e. leaf relative water content, chlorophyll, stomatal conductance, ion leakage in the leaf tissues) and some plant growth parameters (total leaf number, number of dried leaf, main stem diameter, plant crown diameter, plant height, fresh and dry weight of root) of ornamental kale (Brassica oleracea L. var. acephala) plant grown under saline conditions. Four doses of NaCl (NaCl1:30, NaCl2:60, NaCl3:90, NaCl4:120 mM), three doses of Ca(NO3)2 (CaN1:5, CaN2:10, CaN3:15 mM), groups combined together in all doses of NaCl and Ca (NO3)2 and control (NaCl0:0 + CaN0:0) were applied into the pots with three replications. Ca (NO3)2 was applied to the leaf surface of the plants in the pots to be applied as Ca (NO3)2 spray. When the plants reached a certain maturity (two weeks after transfer to the pot), salt stress applications were started. Ca (NO3)2 treatments have applied after one week from salt stress applications. Calcium nitrate treatements applied under salt stress conditions had positive effects and increasing in effect on all parameters examined except for chlorophyll and ion leakage in leaf tissues of the plant. With increasing in calcium nitrate concentration, morphological and physiological characteristics of plants were observed increases in general. It was concluded that the increase of the number of leaves by NaCl2+CaN3 application can be minimized with CaN3 (with 15 mM Ca (NO3)2) stress caused by 60 mM salt concentration According to the results of the research, calcium nitrate applications can be recommended for ornamental kale plants grown under salt stress conditions especially limiting the negative effects of stress and to minimize such damage.
