“…However, Kanagaraj and Desingh [29] showed in seven varieties of sesame a reduction in chlorophyll accompanied by a decrease in photosynthesis and the activity of photosynthetic enzymes following an increase in salinity. This drop in chlorophyll is due to the suppression of the enzymes responsible for its synthesis [30].…”

Salinization is a global environmental problem. It is particularly prevalent in Africa in areas with a low rainfall trend such as the Senegalese groundnut basin where 20% of the land is affected. It reduces global food production by more than 10%. In Senegal, sesame (Sesamum indicum L.) moderately tolerant to drought and salinity is increasingly cultivated. It is an alternative to fight poverty in rural areas and allows the revaluation of salty land. The objective of this work is to evaluate at the early stage of reproduction the effect of salinity on the chlorophyll and ion (Na+ and Cl−) contents of four African varieties of sesame. The experimental device consists of randomized blocks with two factors and three repetitions. The sesame variety factor consists of four modalities (AS09, AS14, AS15 and AS25). The salinity factor or abiotic stress (NaCl) includes three modalities (0 mM, 17 mM and 34 mM). The parameters evaluated are the contents of Na+ and Cl− ions and of chlorophylls (Chl a, Chl b and total Chl). The results showed that the contents of chlorophylls (Chl a, Chl b and Chl) and Cl− and Na+ ions of sesame leaves increased with NaCl at 44 days after sowing. The Cl− contents of sesame leaves are higher than those of Na+ in all treatments. Chlorophyll increased with sesame varieties and salinity. Variety AS15 produced the greatest amounts of chlorophyll. Sesame, an inclusive-type plant, compartmentalizes Cl− and Na+ ions at the leaf level in vacuoles. He developed a tissue tolerance to salinity.

“…Salt stress was found to strongly inhibit the uptake and accumulation of N in different plant parts of green chireta, Andrographis paniculata [14]; cabbage, Brassica oleracea [19]; canola, Brassica napus [78]; cotton, Gossypium hirsutum [61]; gray poplar, Populus × canescens [20]; saltmarsh grass, Spartina alterniflora [65]; sesame, Sesamum indicum [79]; and wheat, Triticum aestivum [67]. However, the uptake and accumulation of N in response to salt stress depend on different plant and soil factors [80].…”

“…However, the uptake and accumulation of N in response to salt stress depend on different plant and soil factors [80]. Kanagaraj and Desingh [79] observed variations in foliar N among different varieties of sesame, where the maximum reduction was found at the highest dose of NaCl. The decline in the uptake of N by plants could be due to the increased uptake and accumulation of Cl.…”

Abiotic Stress in Plants

High salt concentration in soil is a major abiotic stress, which adversely influences the growth, overall development, and productivity of crops. More than 20% of the land of the world used for crop production is adversely affected by high salt concentration. The problem of salt stress becomes a major concern when previously fertile, productive agricultural lands are salinized more profoundly as a result of anthropogenic activities along with natural causes. Therefore, this review is focused on various aspects of salt-affected soils (SAS), their effects on plants, and different approaches for reclamation of SAS to enhance the potentiality for crop production. Salt-affected soils are categorized into saline, saline-sodic, and sodic soils based on the amount of total soluble salts as expressed by electrical conductivity (EC), sodium adsorption ratio (SAR), exchangeable sodium percentage (ESP), and soil pH. The inhibition of plant growth in saline soils is mainly induced by osmotic stress; reduced uptake of essential macro-and micronutrients, including nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu); and specific toxicities of sodium (Na) and chloride (Cl). Sodic soils adversely affect the plant through high soil pH and poor physical condition resulting from an excessive amount of exchangeable Na. Different plants respond to salt stress in different extents. Saltaffected soils must be reclaimed to restore their productivity for increasing food production. The approaches for the management of SAS include leaching, incorporation of different organic and inorganic amendments, mulching, and development of salt-tolerant crops. The suitability of approaches depends on several considerations such as cost of reclamation, the time required, the extent of the salt stress, soil properties, availability of technology, and other environmental factors. Among different strategies, the incorporation of organic amendments is beneficial, costeffective, environment friendly, and sustainable for amelioration of salt stress and enhancement of crop production due to the extensive roles of organic amendments in improving the soil's physical (structural stability, porosity, and permeability), chemical [pH, EC, ESP, organic matter, cation exchange capacity (CEC), and Na leaching], and biological and/or biochemical (microbial abundance, microbial activity, biomass carbon, and enzymatic activities) properties.

“…When there is a decrease in salinity, plant roots will typically respond by absorbing more nitrate. When there is a rise in the concentration of salt in the soil, this phenomenon takes place [22,23]. ROS are primarily found in the chloroplast, mitochondria, and peroxisome as a harmful consequence of aerobic metabolism [24,25], and others have shown that increased generation of these reactive oxygen species (ROS) leads to lipid peroxidation, which in turn disrupts photosynthesis and membrane permeability and destroys nucleic acids, inhibits enzymes, and activates programmed cell death [26].…”

The presence of salt in the soil is a major environmental factor that might reduce grapevine productivity. Excessive salt in the soil causes soil salinity, which in turn causes osmotic stress and toxicity to the grapevine’s root system. This can lead to stunted grapevine development, decreased harvests, and inferior fruit quality. Salinity can alter the physical characteristics of soil, making it less porous and less able to absorb water. This can amplify the negative impacts of salinity on grapevine development and harvest success. Numerous factors influence the severity of salinity’s impact on grapevines. The age and rootstock of the vine, as well as the grape variety, are other important factors. The effects of salinity on grapevine development and production vary with the grapevine’s developmental stage. The salinity of the environment can have a greater effect on the vegetative growth stage than the reproductive growth stage. The reproductive phase is brief and relatively immune to salt stress. Grapevines are especially vulnerable to the negative effects of salt stress during the vegetative growth stage, when the plant’s tissues are still developing. These factors can have a negative impact on grapevine health, leading to poorer yields. Grapevine production is less sensitive to salinity when the plants are in the reproductive phase. Salinity, which decreases sugar concentration, increases acidity, and alters flavor, can still have an impact on fruit quality. Growers can take many measures to reduce the negative effects of salt on grapevines. Choose salt-tolerant grape types and rootstocks, enhance drainage to cut down on salt buildup, and use irrigation methods that minimize salt leaching. In conclusion, salinity can significantly affect grapevine development and harvest success.
