While salinity is increasingly becoming a prominent concern in arable farms around the globe, various treatments can be used for mitigation of salt stress. Here, effective presence Azotobacter sp. inoculation (A1) and absence (A0) was evaluated on Iranian licorice plants under NaCl stress (0 200 mM) (S0 S1, respectively). In this regard, 16 (Glycyrrhiza glabra L.) accessions were effects photosynthesis chlorophyll fluorescence. Leaf samples measured photosynthetic pigments (via spectrophotometer), stomatal trichome-related features SEM), along with several other morphological biochemical features. The results revealed an increase amount carotenoids that caused by bacterial inoculation, which 28.3% higher than non-inoculated treatment. Maximum initial fluorescence intensity (F0) (86.7) observed 'Bardsir' accession. Meanwhile, highest variable (Fv), maximal (Fm), maximum quantum yield (Fv/Fm) (0.3, 0.4, 0.8, respectively) 'Eghlid' Regarding anatomical observations leaf structure, reduced density but increased trichome density. Under effect mitigated. With stress, length width increased, compared to condition no inoculation. Minimum malondialdehyde content 'Mahabad' accession (17.8 μmol/g FW). Principle component analysis (PCA) showed 'Kashmar', 'Sepidan', 'Bajgah', 'Kermanshah', 'Taft' categorized same group while being characterized better performance aerial parts plants. Taken together, present generally indicated selecting best genotypes, exogenous applications Azotobacter, improve outcomes cultivation industrial purposes harsh environments.

Effect of Biochar and Compost Addition on Mitigating Salinity Stress and Improving Fruit Quality of Tomato

Agronomy, Journal Year: 2023, Volume and Issue: 13(9), P. 2197 - 2197

Published: Aug. 22, 2023

To overcome food security, sustainable strategies for reclamation and the subsequent utilization of salt-affected soils crop production are needed. The aim current study was to evaluate impacts compost biochar addition on growth fruit quality tomato under salinity stress. For this purpose, soil spiked with analytical grade sodium chloride achieve a 6 dS m−1 level pot experiment. After 30 days spiking, (2%) were added in selected pots. seedling transplant, recommended doses NPK fulfill nutrient requirements plants. Plants harvested after 90 transplantation. Results revealed that caused significant reduction 28.4% SPAD value, 23.5% Ft, 22.6% MSI, 12.1% RWC, 18.3% Chl. a, 13.7% b, 16.5% T. as compared un-amended non-saline control physiological attributes Similarly, decrease 26.9–44.1% obtained control. However, saline soil, (alone or together) demonstrated improvement plant (i.e., up 45%) over respective Moreover, combined application significantly reduced (Na+) shoots roots plants by 40% 47%, respectively, Our findings suggest could be useful reduce salinity, alleviate salinity-induced phytotoxicity, subsequently improve productivity soil.

Silicon mitigates the negative impacts of salt stress in soybean plants

Journal of the Science of Food and Agriculture, Journal Year: 2023, Volume and Issue: 103(9), P. 4360 - 4370

Published: Feb. 15, 2023

Soybean is widely cultivated around the world, including regions with salinity conditions. Salt stress impairs plant physiology and growth, but recent evidence suggests that silicon (Si) able to mitigate this stressful condition. Therefore, purpose of study was evaluate how different strategies Si application impact on salt tolerance an intermediate accumulator species (soybean). we applied four treatments: Si-untreated plants (Si 0); foliar spraying at 20 mmol L-1 F); nutritive solution addition 2.0 mol R), combined plus F + R). We investigated modified leaf gas exchange, photosynthetic pigments, chlorophyll fluorescence, relative water content (RWC), nutrient accumulation, ion homeostasis soybean submitted levels (50 100 NaCl).Salinity induced expressive reduction in status, growth soybean, while promoted contrary effects increased potassium (K+ ) pigment content, fluorescence parameters, exchange attributes. Additionally, enhanced accumulation associated decreased Na+ uptake improved morpho-physiological growth.The use exogenous can be efficient strategy attenuate harmful plants.

Salinity is a global challenge to sustainable agriculture, impacting plant growth at cellular and functional levels. Nevertheless, silicon (Si), multifunctional micro-element, plays vital role in restoring maintaining development during unfavourable abiotic conditions such as high salinity exposure. Therefore, the current research, two levels [S1; 1 M (1000 mM) NaCl S2; 2 (2000 NaCl] were used assess effects of exogenous Si (Si-1; 150 mg/L Si-2; 250 mg/L) on key biological characteristics especially metabolite profiles Panicum turgidum plants. Our findings revealed that salt stress negatively affected plants through content (Na+ Cl−) further antagonized essential nutrient balance tissues; increased NH4+, but lowered NO3− K+ both roots leaves. The excessive production NH4+ led over-accumulation methylglyoxal (MG), resulting hyper-accumulation sugars altering concentrations amino acids, thereby inducing diabetes-like symptoms P. Interestingly, application restored by reducing oxidative damage modifying nutritional status, metabolic biochemical Specifically, Si-2 showed improvement indictors leaves under study also demonstrated substantially reduced NH4+-mediated MG-induced lowering concentration MG, up-regulating antioxidant capacity various enzymes glyoxalase I (Gly-I), II (Gly-II), glutathione (GSH), glutamine: 2-oxoglutarate aminotransferase (GOGAT), nitrate reductase (NR), glutamine synthetase (GS), glutamate dehydrogenase (GDH); with concomitant changes sugar/carbohydrates turgidum.

Abstract Castanopsis fissa is a native, broadleaf tree species in Guangdong with characteristics of barrenness and fast growth often used as pioneer for vegetation restoration excellent ecological benefits. To explore the response C.fissa to drought, this study investigated drought tolerance mechanism using physiological proteomic assessments. Using potted continuous experimental method normal water supply control, we measured photosynthetic parameters, antioxidant enzyme activities, osmoregulatory substances C. stress 1 4 weeks, respectively. In addition, TMT quantitative proteomics identify differentially expressed proteins (DEPs) between drought-stress-treated leaves control leaves. With extension time, indexes peroxidase (POD) activity showed decreasing trend. The malondialdehyde (MDA) content; superoxide Dismutase (SOD) catalase (CAT) activities; proline (Pro), soluble sugar (SS) protein (SP) contents an overall increasing trend, all which reached significant differences at w stress. We identified 177 529 DEPs 2 weeks drought-stress leaves, respectively, reference These were closely related metabolic processes such photosynthesis, energy carbohydrate metabolism, defense, transcriptional regulation, signal ion transduction. Drought mainly affects synthesis degradation At stress, expression carbon pyruvate metabolism ribosome-related was significantly changed, however, processing endoplasmic reticulum spliceosome-related increased plant alleviate effect unavailability, drought-stressed its oxidative protective system eliminate excess reactive oxygen (ROS) also Pro SP maintain intracellular osmotic potential balance.
