[PMID: 38663084 DOI: 10.1016/j.jenvman.2024.120917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 03/29/2024] [Accepted: 04/13/2024] [Indexed: 05/04/2024]
Abstract
Permafrost regions play an important role in global carbon and nitrogen cycling, storing enormous amounts of organic carbon and preserving a delicate balance of nutrient dynamics. However, the increasing frequency and severity of wildfires in these regions pose significant challenges to the stability of these ecosystems. This review examines the effects of fire on chemical, biological, and physical properties of permafrost regions. The physical, chemical, and pedological properties of frozen soil are impacted by fires, leading to changes in soil structure, porosity, and hydrological functioning. The combustion of organic matter during fires releases carbon and nitrogen, contributing to greenhouse gas emissions and nutrient loss. Understanding the interactions between fire severity, ecosystem processes, and the implications for permafrost regions is crucial for predicting the impacts of wildfires and developing effective strategies for ecosystem protection and agricultural productivity in frozen soils. By synthesizing available knowledge and research findings, this review enhances our understanding of fire severity's implications for permafrost ecosystems and offers insights into effective fire management strategies.

Morphoanatomical and Physiological Adaptations of Triticum aestivum L. against Allelopathic Extract of Trianthema portulacastrum L. (Horse purslane). ACS OMEGA 2023; 8:35874-35883.

Abstract
Weed infestation can be harmful to crop growth and cause severe losses in yield by absorbing nutrients and releasing inhibitory secondary metabolites and thus needs to be controlled for food security. The use of synthetic herbicides is one of the most widely applied methods, but its frequent usage is a serious threat to health and the environment and develops resistance in weeds. Allelopathy is an eco-friendly bio-control method, and Trianthema portulacastrum extracts are known to be effective against various weeds in the crop of Triticum aestivum (wheat), but their effect on the main crop (wheat) is still unknown. The pot experiment was carried out, and various concentrations (30, 60, and 100%) of root and shoot extracts of T. portulacastrum and a synthetic herbicide (Metafin Super) along with control (distilled water) were applied to the wheat plants. Various morphological, physiological, and anatomical parameters were recorded under natural conditions. The objective of this study was to explore the allelopathic impact of T. portulacastrum compared to the synthetic herbicide on the growth of wheat. This study displayed that various growth characteristics of wheat were significantly affected at p ≤ 0.05 by root and shoot water extracts of T. portulacastrum but were less inhibitory as compared to the synthetic herbicide. This inhibition of the growth of wheat was coupled with a significant increase in total free amino acids, K ions, CAT (catalase), proline, epidermal and cortical thickness, and abaxial stomatal density. In addition, a reduction in growth parameters was correlated with a decrease in photosynthetic pigments. This study revealed that the use of T. portulacastrum extracts could be safer than synthetic herbicides for wheat plants and would be beneficial to control weeds in a wheat field.

Biochar and Seed Priming Technique with Gallic Acid: An Approach toward Improving Morpho-Anatomical and Physiological Features of Solanum melongena L. under Induced NaCl and Boron Stresses. ACS OMEGA 2023; 8:28207-28232. [PMID: 38173954 PMCID: PMC10763624 DOI: 10.1021/acsomega.3c01720] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Accepted: 07/12/2023] [Indexed: 01/05/2024]
Abstract
Dynamic shifts in climatic patterns increase soil salinity and boron levels, which are the major abiotic factors that affect plant growth and secondary metabolism. The present study assessed the role of growth regulators, including biochar (5 g kg-1) and gallic acid (GA, 2 mM), in altering leaf morpho-anatomical and physiological responses of Solanum melongena L. exposed to boron (25 mg kg-1) and salinity stresses (150 mM NaCl). These growth regulators enhanced leaf fresh weight (LFW) (70%), leaf dry weight (LDW) (20%), leaf area (LA), leaf area index (LAI) (85%), leaf moisture content (LMC) (98%), and relative water content (RWC) (115%) under salinity and boron stresses. Physiological attributes were analyzed to determine the stress levels and antioxidant protection. Photosynthetic pigments were negatively affected by salinity and boron stresses along with a nonsignificant reduction in trehalose, GA, osmoprotectant, and catalase (CAT) and ascorbate peroxidase (APX) activity. These parameters were improved by biochar application to soil and presoaking seeds in GA (p < 0.05) in both varieties of S. melongena L. Scanning electron microscopy (SEM) and light microscopy revealed that application of biochar and GA improved the stomatal regulation, trichome density, epidermal vigor, stomata size (SS) (13 381 μm), stomata index (SI) (354 mm2), upper epidermis thickness (UET) (123 μm), lower epidermis thickness (LET) (153 μm), cuticle thickness (CT) (11.4 μm), trichome density (TD) (23 per mm2), vein islet number (VIN) (14 per mm2), vein termination number (VTN) (19 per mm2), midrib thickness (MT) (5546 μm), and TD (27.4 mm2) under salinity and boron stresses. These results indicate that the use of inexpensive and easily available biochar and seed priming with GA can improve morpho-anatomical and physiological responses of S. melongena L. under oxidative stress conditions.
