Abstract Salt stress is a major threat to crop agricultural productivity. Salinity affects plants’ physiological and biochemical functions by hampering metabolic functions and decreasing photosynthetic rates. Salinity causes hyperosmotic and hyperionic stress, directly impairing plant growth. In this study, eggplant seeds primed with moringa leaf extract (5%, 10%, and 15%), nano-titanium dioxide (0.02%, 0.04%, and 0.06%), and ascorbic acid (0.5, 1, and 2 mM) at different NaCl salt (0, 75, and 150 mM) concentration were grown. The germination attributes (final germination percentage, germination index, mean germination time, and mean germination rate) and growth (root length, shoot… More >

Abstract Strontium has similar chemical properties to calcium and has recently been recognized as a non-essential beneficial element for plants. In order to compare the effects of strontium and calcium on improving salt tolerance of Chinese cabbage during the germination stage, 2, 4, and 8 mmol/L of SrCl₂, CaCl₂ or an equimolar mixture of both were added separately to a 150 mmol/L NaCl solution. The results showed that Ca-Sr addition significantly increased seed viability, seed vigor, seed germination rate and seed germination uniformity of Chinese cabbage compared with the salt-control group. The differences in germination percentage (GP)… More >

Abstract Soil salinization is a prominent global environmental issue that considerably affects the sustainable development of agriculture worldwide. Maize, a key crop integral to the global agricultural economy, is especially susceptible to the detrimental impacts of salt stress, which can impede its growth and development from the germination phase through to the seedling stage. Soil salinity tends to escalate due to improper irrigation methods, particularly in arid and semi-arid environments. Consequently, it is essential to evaluate potential genotypes and select those with high salt tolerance. In this study, 39 popcorn kernel genotypes were examined under varying… More >

Abstract The Northeast region is the main producer of guava in Brazil, generating employment and income. However, water availability means that producer’s resort to using water with high salinity, which harms plant development, especially during the seedling formation phase. The adoption of techniques that mitigate the deleterious effect of salinity is increasingly necessary, such as the use of elicitors such as ascorbic acid. The purpose of this study was to analyze the morphophysiology of guava seedlings under saline and ascorbic acid levels. The study was carried out by applying treatments composed of five saline levels (SL… More >

Abstract Salinity stress is a major constraint on agricultural productivity, particularly in arid and semi-arid regions. This study evaluated the potential of Ascophyllum nodosum extract (ANE) in mitigating salinity-induced stress and enhancing the growth and physiological performance of Portulaca oleracea L. under NaCl concentrations of 0, 50, 70, and 100 mM for 50 days. A two-way ANOVA assessed the effects of NaCl concentration, ANE treatment, and their interaction. The results showed that ANE significantly increased plant height at 50 mM NaCl (p = 0.0011) but had no effect at higher salinity levels (p > 0.05). Shoot dry weight was… More >

Abstract Rice is a crucial food crop globally. Soil salt stress has adverse effects on the physiology and biochemistry of rice, leading to ionic toxicity and disrupted metabolism. Research aimed at improving salt tolerance and understanding its underlying mechanisms in rice is becoming increasingly important. Phytohormones are crucial in managing rice’s reaction to salt stress by controlling its physiological and biochemical functions. Some phytohormones can improve salt tolerance in rice by affecting gene programming, protein expression, and salt stress signaling, thereby helping rice adapt to salt-stressed environments. This review highlights recent advancements in understanding how various More >

Abstract Background: Aldehyde dehydrogenase (ALDH) genes constitute an important family of supergenes that play key roles in synthesizing various biomolecules and maintaining cellular homeostasis by catalyzing the oxidation of aldehyde products. With climate change increasing the exposure of plants to abiotic stresses such as salt and drought, ALDH genes have been identified as important contributors to stress tolerance. In particular, they help to reduce stress-induced lipid peroxidation. Objectives: This study aims to identify and characterize members of the ALDH supergene family in Phaseolus vulgaris through a genome-wide bioinformatic analysis and investigate their role in response to abiotic stressors such… More >

Abstract Globally, salinity is a brutal environmental constraint that poses a major threat to agriculture worldwide, causing nutrient imbalances and oxidative stress, leading to reduced crop yields and quality. Date palm waste from the agro-industry is a major environmental problem, but its conversion to biochar for soil amendment could help alleviate the effects of salinity stress. Pepper is a commonly grown horticultural crop that is sensitive to salinity. That’s why the current experiment was conducted with the novel idea of exploring the potential use of biochar-based fertilizer derived from date palm waste as a mitigation strategy… More >

Abstract Soybean (Glycine max) is a potential legume crop, but it cannot thrive in mild salinity. Salicylic acid (SA) is a renowned plant growth hormone that improves tolerance to saline conditions. Hence, the study was performed to understand the functions of priming seeds and supplementation of SA in modulating salt tolerance in soybean seedlings. When exposed to salt stress, soybean seedlings showed considerably higher contents of hydrogen peroxide (H₂O₂) and malondialdehyde (MDA) while having decreased germination and growth factors, water contents, and photosynthetic pigments. The germination rate, final germination percentage, germination index, germination energy, and seed vigor index… More >

Abstract Salt stress inhibits plant growth and affects the biosynthesis of its secondary metabolites. Flavonoids are natural compounds that possess many important biological activities, playing a significant role in the medicinal activity of Eucommia ulmoides (E. ulmoides). To investigate the mechanism by which salt stress affects the biosynthesis of flavonoids in E. ulmoides, a comprehensive analysis of metabolomics and transcriptomics was conducted. The results indicated that salt stress led to the wilting and darkening of E. ulmoides leaves, accompanied by a decrease in chlorophyll levels, and significantly induced malondialdehyde (MDA) and relative electrical conductivity. During salt stress, most metabolites in… More >
