Biostimulants such as seaweed extracts are emerging crop management products that can enhance productivity and nutritional quality under abiotic stress conditions. Therefore, this study aimed to assess the effectiveness of a seaweed-derived biostimulant (Kelpak®) in alleviating salinity spinach. A greenhouse experiment which consisted five treatments (T1 = Control plants (no NaCl or extract (SWE), T2 subjected 300 mM without SWE, T3 + 1% dilution T4 2.5% T5 5% SWE) was conducted. The results showed addition SWE reduced growth, relative water content, chlorophyll, quality. Similarly, induced severe oxidative stress, indicated by excessive amounts superoxide radicals, malondialdehyde upregulation catalase, peroxidase, polyphenols, flavonoids. Interestingly, treated with displayed substantial enhancement performance, reduction improved quality, characterised considerable minerals, proximate constituents, vitamins. These support use enhancing growth spinach saline cultivation.

In this study, 20-day-old soybean plants were watered with 100 mL of mM NaCl solution and sprayed silica nanoparticles (SiO2 NPs) or potassium silicate every 3 days over 15 days, a final dosage 12 mg SiO2 per plant. We assessed the alterations in plant's growth physiological traits, responses bacterial microbiome within leaf endosphere, rhizosphere, root endosphere. The result showed that type silicon did not significantly impact most plant parameters. However, communities endospheres had stronger response to NPs treatment, showing enrichment 24 13 microbial taxa, respectively, compared which led 9 8 taxonomic respectively. rhizosphere less sensitive NPs, enriching only 2 clades, clades enriched by treatment. Furthermore, treatment beneficial genera, such as Pseudomonas, Bacillus, Variovorax likely enhancing salinity stress resistance. These findings highlight potential for foliar application sustainable farming plant-microbe interactions improve tolerance.

Salt stress disrupts ionic homeostasis and induces oxidative damage, leading to reduced plant growth development. Determining the lethal dose of NaCl is essential for developing effective mitigation strategies. Potassium other antioxidant regulatory compounds often prove insufficient in addressing salt-induced toxicity, especially wheat. This laboratory experiment aimed determine concentration that reduces by 50% evaluate effectiveness different approaches involving potassium thiourea supplementation at 0 mM, 10 15 mM under identified condition.

Six new cultivars of Petunia × hybrida Grandiflora (‘Aphrodita White’, ‘Success Salmon Morn’, ‘Dreams Red Picotee’, ‘Hulahoop Blue’, ‘Limbo ‘Falcon Burgundy’) were studied in urbanized areas the Arctic zone (the city Polyarnye Zori, Polar-Alpine Botanical Garden-Institute Kirovsk). Phenological analysis showed that flowering duration was almost same, 90–100 days, except for Morn’ (74 days) and Picotee’ (104 days). Biometrical maximum diameter flowers found Cv. minimum typical Burgundy’. In general, varieties with a flower 6–8 cm predominated. The number per plant low Burgundy’ (1–3) high Blue’ (12–16).
