“…Other studies corroborated in that while no significant difference was identified, in some instances, chlorophylls a and b concentrations and carotenoids were lower in the saline conditions than t control [43,44,46,47,[49][50][51]. Accordingly, other evidence of reduced chlorophyll and carotenoid contents resulting from salinity was noted in wheat [42,52,53], Salvinia molesta and Pistia stratiotes [54], pea [55,56], mangrove [57], bean [58,59], cotton [60], oats [34] and olive saplings [61].…”

Chenopodium quinoa is a promising species for future food security and combating climate change due to its nutritional content and halophytic nature. This study focuses on the temporal differential responses of the salt-tolerant (Chadmo) and the salt-sensitive (Kankolla) under control (CK) and 400 mM NaCl arranged under the randomised block designed (RBD). Biochemical features assessed and results indicate a significant difference (p<0.05) being identified by ANOVA and Tukey analyses in total chlorophyll (CHL), carotenoids (CAR), proline, glycine betaine (GB), soluble sugars, K+, Na+, K+/Na+ ratio, Mg2+ and Ca2+ in both genotypes between the CK and 400 mM NaCl. Na+ increased while K+ and the bivalent ions Mg2+ and Ca2+ decreased progressively with time points (CK and 24 h) in both genotypes but more pronounced in Kankolla. Proline increased by 24.45 and 18.63% between the CK and 24 h after exposure to 400 mM NaCl in Chadmo and Kankolla, respectively. Similarly, significant increases were observed in ABA, glycine betaine and soluble sugars from the CK to 24 h after exposure to 400 mM NaCl in both genotypes. Using these biochemical responses to salinity, Chadmo proved to be the better-performing genotype when exposed to 400 mM NaCl and hence identified as the salt-tolerant genotype.

“…KRL1-4, a promising salt-tolerant genotype, was developed in Northern India via the crossing of Kharchia 65 and WL711 [23]. This genotype showed improved yield performance under saline soil in Northern India; however, it recorded low yield output when grown in Pakistan because of heavier soils and waterlogging events [24].…”

In recent years, the progressive escalation of climate change scenarios has emerged as a significant global concern. The threat to global food security posed by abiotic stresses such as drought, salinity, waterlogging, temperature stress (heat stress, freezing, and chilling), and high heavy metal accumulation is substantial. The implementation of any of these stresses on agricultural land induces modifications in the morphological, biochemical, and physiological processes of plants, leading to diminished rates of germination, growth, photosynthesis, respiration, hormone and enzyme activity disruption, heightened oxidative stress, and ultimately, a reduction in crop productivity. It is anticipated that the frequency of these stresses will progressively escalate in the future as a result of a rise in climate change events. Therefore, it is crucial to develop productive strategies to mitigate the adverse effects of these challenges on the agriculture industry and improve crop resilience and yield. Diverse strategies have been implemented, including the development of cultivars that are resistant to climate change through the application of both conventional and modern breeding techniques. An additional application of the prospective and emerging technology of speed breeding is the acceleration of tolerance cultivar development. Additionally, plant growth regulators, osmoprotectants, nutrient and water management, planting time, seed priming, microbial seed treatment, and arbuscular mycorrhiza are regarded as effective methods for mitigating abiotic stresses. The application of biochar, kaolin, chitosan, superabsorbent, yeast extract, and seaweed extract are examples of promising and environmentally benign agronomic techniques that have been shown to mitigate the effects of abiotic stresses on crops; however, their exact mechanisms are still not yet fully understood. Hence, collaboration among researchers should be intensified to fully elucidate the mechanisms involved in the action of the emerging technologies. This review provides a comprehensive and current compilation of scientific information on emerging and current trends, along with innovative strategies to enhance agricultural productivity under abiotic stress conditions.

“…The development and selection of new amphiploid lines of cereals are crucial to identify the most performing ones in terms of crop production and survival in harsh environmental conditions [1,2]. Nowadays, one of the main factors reducing plant productivity is the poor seedling establishment in dry and semi-arid areas due to different abiotic stresses, such as rare annual precipitation, high evaporation, water scarcity, and soil salinity [3,4]. Primary Trans Chromosomal Tritipyrum (PTCT) lines, derived from the natural hybridization of Triticum aestivum L. and Thinopyrum bessarabicum, are recombinant chromosomal lines of hexaploid Tritipyrum, a new salt-tolerant species of cereal [5,6].…”

Primary Trans Chromosomal Tritipyrum (PTCT) amphiploid is a new cereal grown in saline soil and brackish water for grain and forage production. We evaluated the tolerance to seed deterioration in 13 promising PTCT lines, assessing accelerated aging (AA) tests by using AA boxes with 100% relative humidity at 40 °C for 72 h. The (Ma/b)(Cr/b)F4 and (St/b)(Cr/b)F4) PTCT lines, more sensitive to seed aging, were primed with NaCl, Salicylic Acid (SA), and Polyethylene Glycol (PEG) to increase the seed vigor of artificially aged seeds. Germination and emergence traits, biochemical parameters, and chromosomal abnormalities induced by artificial aging were measured in deteriorated and not-deteriorated seeds. The highest reduction percentages related to seed vigor were observed in (Ka/b)(Cr/b)F2 (34.52) and La(4B,4D)/b (28.15) lines, while the lowest was found in (Ma/b)(Cr/b)F4 (7.65) and (St/b)(Cr/b)F4 (7.46) lines. Seed aging also increases electrolytes, potassium, and protein leakages. Chromosomal abnormalities are caused by seed aging that interferes with chromosome behaviors during cell division. Seed priming on aged seeds revealed an increase in the germination percentage (GP) with PEG treatment, while the priming by SA showed an increase in seedling traits, such as the seedling length (SL2). In conclusion, we highlighted the potential use of different PTCT lines and the effective use of seed priming on deteriorated seed to enhance seed viability and seedling vigor as a useful tool for sustainable agriculture.
