“…However, in the case of shoot, applying biochar as a sole treatment resulted in a highly significant amelioration of the harmful effects induced by salinity stress, causing a remarkable reduction in total soluble proteins and total soluble carbohydrate contents of salt-stressed seedlings. These results are in concurrence with the findings of Osman et al [46].…”

Aim: This study was conducted to determine if applying biochar made from fish waste to the soil can alleviate the adverse impacts of salinity stress on maize (Zea mays L.) seedling growth. Materials and Methods: Maize plants were cultivated in two groups of pots; the first group had the soil without any additions, and the second group had the soil mixed with biochar (1% w/w). Each group was irrigated with saline water (0, 50 and 150 mM NaCl). Results: According to the findings, Zea mays exposed to salt stress showed a significant decrease in growth traits such as shoot and root length, fresh weight, and dry weight of shoot and root, compared to untreated control. The addition of biochar significantly enhanced these attributes. As salinity levels increased, the value of photosynthetic pigments gradually declined. Applying biochar to the soil significantly increased the amounts of Chl a, Chl b, and carotenoid. Salt-stressed seedlings treated with biochar have lower levels of soluble sugars, soluble proteins, and total free amino acids at 150 mM NaCl + FWB of the shoot. The findings demonstrate that applying biochar to salt-stressed seedlings caused their proline content to increase noticeably at the highest salinity level (150 mM NaCl). The contents of Na+ and Cl- were positively affected by increasing salt stress. Increasing salt stress had a deleterious impact on K+, Ca2+, and Mg2+ levels. On the other hand, applying FWB raised the content of K+, Ca2+, and Mg2+ while decreasing the amounts of Na+ and Cl-. Conclusion: Biochar made from fish waste has the potential to reduce salinity stress significantly.

Maize, along with rice and wheat, is a popular staple food crop worldwide, and the most widely produced cereal crop. It is a versatile crop that may be utilized as a source of raw materials for human and animal fodders. Low agricultural yield and rapid population expansion significantly threaten future food security. Maize production is hampered by biotic and abiotic causes, with abiotic factors being the most critical limitation to agricultural output worldwide. Soil salinity is a key abiotic factor that reduces agricultural production by imposing negative impacts at several life cycle phases, including germination, seedling, vegetative, and reproductive development. Maize plants experience many physiological changes due to osmotic stress, toxicity of particular ions, and nutritional imbalance induced by salt stress. The degree and duration of stress, crop growth phases, genetic characteristics, and soil conditions influence yield reduction. Maize plants can tolerate salt stress involving a complex mechanism by changing their physiological, biochemical, and metabolic activities like stomatal functioning, photosynthesis, respiration, transpiration, hormone regulation, enzymes, metabolite generation, etc. After studying the salt tolerance mechanisms of maize plants under stress, integrated management techniques should be developed for maize agriculture in saline settings. Therefore, the study of plant responses to salt stress, stress tolerance mechanisms, and management strategies is one of the most imperative research fields in plant biology, and the study will focus on the effects of salt stress in different growth stages, plant tolerance mechanisms, and agronomic management practices for successful maize production all over the world.

“…Under saline conditions, the reduction of seedling root lengths was a common phenomenon in many plants (Ebeed et al, 2019;Osman et al, 2019;Budran et al, 2023), because roots were the first organs exposed to soil environments. Consequently, the extension of root systems was critical for many plants to maintain cellular hydration by avoiding water deficit (Huang, 2008;Wu, 2013).…”

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ 50 T HIS STUDY deals with the effects of tri-factorial interaction on some traits (elongation; weight and biomass accumulation efficiency of roots) and anatomical features of seedling Simmondsia chinensis roots. The obtained data indicated that, the moderate sodicity affected the root length which was enhanced by the sub optimal and optimal temperatures with low salinity stress. The decreased root elongation was inhibited under supra optimal temperature with decreased Ψ s . Statistically, the Ψ s had a dominant role while temperature effect was secondary on the root length and weight. It was found that, the temperature ranges from 20 to 28 was favorable for well development of the root anatomical structures and the root hairs formation, particular at low osmotic stress and moderate sodicity. Adversely, the elevated temperature had a deleterious effect on the root circulation which caused a wider vascular cylinder with narrower root cortex, as well as a distortion {lysis} of parenchymatous cells. The effect of the investigated factors and their combinations on the efficiency of cortical layer and xylem vessels was discussed.
