Increased soluble salts in soil and irrigation water threaten the sustainability of crops. This causes food insecurity directly by reducing staple crop yield indirectly limiting fodder forage production. Recently, plant-growth-promoting rhizosphere microorganism utilization improved productivity under stress. Therefore, this research was conducted to find Sorghum bicolor growth improvement potential exogenous application five different Pseudomonas strains salinity a pot experiment. The applied with 1/2-strength Hoagland's nutrient solution as 0 100 mM NaCl for 30 days. Results indicated that reduced vegetative parameters stress-responsive biochemicals nonbacterial treated plants.

Drought stress poses a significant obstacle to agricultural productivity, particularly in the case of oilseed crops such as sunflower ( Helianthus annuus L.). Selenium (Se) is fundamental micronutrient that has been recognized for its ability enhance plant resilience face various environmental stresses. The FH-770 variety was cultivated pots subjected three levels (100% FC, 75% and 50% FC) four Se application rates (0 ppm, 30 60 90 ppm). This research aimed investigate effect exogenously applied on morpho-physiological biochemical attributes improve drought tolerance. Foliar significantly lowered H 2 O (hydrogen peroxide; ROS) (20.89%) accumulation markedly improved glycine betaine (GB) (74.46%) total soluble protein (Pro) (68.63%), ascorbic acid (AA) (25.51%), phenolics (TP) (39.34%), flavonoids (Flv) (73.16%), anthocyanin (Ant) (83.73%), activity antioxidant system superoxide dismutase (SOD) (157.63%), peroxidase (POD) (100.20%), catalase (CAT) (49.87%), which ultimately growth by 36.65% during stress. Supplemental increased shoot content (93.86%) calcium (Ca 2+ ), potassium (K + sodium (Na ) ions roots 36.16%, 42.68%, 63.40%, respectively. supplements at lower concentrations (60 ppm) promoted growth, development, sunflowers controlled water-deficient circumstances. However, selenium treatment photosynthetic efficiency, enzymatic activities, osmoregulation, characteristics, nutrient balance. mechanisms molecular processes through induces these modifications need further investigation be properly identified.

NaHCO3 impairs the growth and fruit yield of tomato plants

Plant Stress, Год журнала: 2024, Номер 11, С. 100354 - 100354

Underground water enriched in NaHCO3 is used farms of the Buenos Aires province for tomato crop irrigation. This farming practice leads to salt accumulation and soil impairment after several seasons cultivation inside greenhouses. work assayed effect on fruit production. Plants Elpida variety Solanum lycopersicum L were grown a hydroponic system. The presence (from 5 mM, as measured underground 10 or 20 mM) reduced K+/Na+ ratio whole plant biomass yield; however, no was observed quality parameters. To test participation ascorbic acid tolerance this stress, two slggp1 Micro-Tom mutant lines deficient antioxidant used. In these experiments plants treated with 0, mM causing an ratio, photosynthesis, yield, leaf shoot dry weight (but without root biomass) delaying ripening time. Wild type mutants responses showed differences at stress conditions. Although treatments caused similar wild plants, results reinforced physiological importance levels optimize growth under non-stressful Taken whole, presented here demonstrated avoiding greenhouse soils

Salt Stress Induces Contrasting Physiological and Biochemical Effects on Four Elite Date Palm Cultivars (Phoenix dactylifera L.) from Southeast Morocco

Plants, Год журнала: 2024, Номер 13(2), С. 186 - 186

Опубликована: Янв. 10, 2024

Understanding the response of date palm (Phoenix dactylifera L.) cultivars to salt stress is essential for sustainable management phoeniculture in Tafilalet, Morocco. It offers a promising avenue addressing challenges presented by increasing salinity irrigation waters, especially because farmers these regions often lack necessary knowledge and resources make informed decisions regarding cultivar selection. This study addresses this issue investigating performance most relied on namely Mejhoul, Boufeggous, Nejda, Bouskri. These were exposed sodium chloride treatment 154 mM, their performances evaluated over three-month period. We examined growth rate, photosynthesis-related parameters, pigments, water status plants, biochemical compounds associated with oxidative stress, osmotic ionic stress. Principle component analysis (PCA) effectively categorized into two distinct groups: salt-sensitive (Mejhoul Nejda) salt-tolerant (Boufeggous Bouskri). findings provide valuable insights farmers, highlighting advantages cultivating Boufeggous Bouskri due superior adaptation conditions. exhibited moderate decrease shoot (25%), enhanced catalase activity, smaller increase anthocyanin content, greater enhancement organic osmolytes compared like Mejhoul (experiencing an 87% reduction elongation) Nejda (exhibiting highest leaf area). Furthermore, Na+/K+ ratio was positively influenced recording values, suggesting its potential as indicator sensitivity palms.

Priming effect of ascorbic acid on the growth and biomass of quinoa under saline conditions

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Май 30, 2025

Ascorbic acid (ASA) is often recommended to mitigate the effects of saline stress on crop growth. However, no such research exists its priming effect growth quinoa ( Chenopodium Willd.). Thus, main goal this study was evaluate potential benefits ASA (0.1 and 0.5 μM) against salt-induced in seedlings. The results showed that significantly improved germination, biomass, especially fresh weight (≥47.14%) dry (≥83.33%) even higher than CK, indicating enhanced plant vigor under salt 200 mM. Additionally, ASA-treated plants chlorophyll carotenoid biosynthesis, with low increased carotenoids by 95.45%, improving photosynthesis. Furthermore, gas exchange, non-photochemical quenching (NPQ), antioxidants enzymes activities, suggesting improve energy dissipation support for oxidative tolerance. Notably, metabolic indicators, proline (≥29.89%) levels, osmotic adjustment. Moreover, effectively mitigated sodium (Na + ) chloride (Cl − roots through potassium (K uptake at least 93.41% elevated K levels 99.76% shoots, underscoring role mediating ion homeostasis salinity. This provides first evidence could enhance biological, physiological biochemical responses quinoa. Applying 0.1 μM/L feasible effective as a concentration suitable conditions.
