Journal of soil science and plant nutrition, Journal Year: 2023, Volume and Issue: 24(1), P. 54 - 73

Published: Dec. 26, 2023

Abstract Melatonin was found in plants the late 1990s, but its function, signaling, and interaction with other phytohormones still unclear. research has increased substantially recent years, including reports on impact of this putative plant hormone under biotic abiotic stress situations. Temperature extremes, salt, drought, hypoxia or anoxia, nutrient deficiency, herbicides, UV radiation stress, heavy metal toxicity are all important obstacles to horticulture crop production worldwide. To deal these environmental challenges, have evolved complex signaling networks. Phytohormones essential for controlling growth, development, responses. Melatonin, a pleiotropic chemical present variety species, recently emerged as powerful regulator tolerance. The purpose review is investigate interplay between melatonin control responses horticultural crops. We explore interactions several various stresses.

Abstract Amidst intensifying global agricultural water demand, optimizing management practices and understanding the role of soil amendments, particularly biochar (BC), in modulating dynamics are critical. Here, we review potential impacts BC on dynamics, elucidate mechanistic underpinnings, identify critical research gaps prospective avenues. In general, modifies structure, hydraulic properties, surface albedo, heat fluxes, which influence storage, energy balance, irrigation paradigms. Depending texture demonstrates a greater reduction bulk density saturated conductivity coarse-textured soils compared to fine-textured soils. application generally increases holding capacity (WHC) while exhibiting no consistent impact infiltration. Increased WHC results from increased porosity, area, aggregation. porosity arises confluence factors, encompassing new pores formation, reorganization pores, aggregation, dilution effects BC, reduced compaction, biotic interactions, including population burrowing invertebrates. tends increase plant-available coarser soils, attributed its hydrophilic nature, augmented specific enhanced overall porosity.

Abstract Salinity stress has become a major threat to worldwide crop production. Exogenous melatonin (MT) appeared as promising treatment against salt in several plant species. However, MT effect on the tolerance of sorghum plants under different saline conditions (moderate and severe) remains ambiguous. This study was carried out explore impact (0, 50, 100 200 µM) foliar application seedlings grown moderate severe using sodium chloride, NaCl (75 150 µM NaCl). treatments were applied solution sand medium pots. The results demonstrated that rising salinity level negatively affected growth, photosynthetic pigments (chlorophylls carotenoids), leaf water status ionic homeostasis (sodium, potassium, calcium ions). Applied-MT specifically at or enhanced osmotic balance, cell membrane stabilizing relative content. These effects associated with an obvious restriction hydrogen peroxide, lipid peroxidation (malondialdehyde content) methylglyoxal. Moreover, antioxidant activities peroxidase, catalase, superoxide dismutase, ascorbate peroxidase enzymes modulated by treatments.

Abstract Background Abiotic stresses, like drought, are the major cause of shrinking plant, growth crop yields and quality. Nanotechnology has provided a significant improvement in increasing plant yield crops under stress conditions. This work assessed potential silicon for mitigating negative effects drought against wheat.

Plant Growth Regulation, Journal Year: 2024, Volume and Issue: 104(1), P. 151 - 167

Published: May 15, 2024

Abstract Salinity stress constitutes one of the main abiotic stresses that considerably reduces crop yield. An approach to enhance plant growth under salt involves addition humic substances (HS) roots or leaves. Here, we evaluated potential use BLACKJAK®, an HS-based product, tolerance in lettuce ( Lactuca sativa L.). For this aim, plants were exposed salinity (100 mM NaCl), + HS: radicular (R)-HS (0.40 mL/L and 0.60 mL/L) foliar (F)-HS (7.50 10.00 mL/L), along with a control (without NaCl). Parameters related growth, Na K accumulation, photosynthetic activity, oxidative stress, enzymatic non-enzymatic antioxidants, as well proline levels evaluated. Results showed R F-HS enhanced tolerance. In addition, offered greater improvement relation shoot fresh weight, relative rate, area, being best dose. This could be associated reduced translocation decreasing /K ratio. Furthermore, HS improved net Rubisco carboxylation efficiency, photosystem II performance, ROS lipid peroxidation.
