Synergistic Effects of Kaolin and Silicon Nanoparticles for Ameliorating Deficit Irrigation Stress in Maize Plants by Upregulating Antioxidant Defense Systems

Plants, Journal Year: 2023, Volume and Issue: 12(11), P. 2221 - 2221

Published: June 5, 2023

Water deficit is a significant environmental stress that has negative impact on plant growth and yield. In this research, the positive significance of kaolin SiO2 nanoparticles in moderating detrimental effects water maize yield investigated. The foliar application (3 6%) NPs (1.5 3 mM) solutions increased variables plants grown under normal conditions (100% available water) drought (80 60% (AW)). addition, treated with demonstrated levels important osmolytes, such as proline phenol, maintained more their photosynthetic pigments (net rate (PN), stomatal conductance (gs), intercellular CO2 concentration (Ci), transpiration (E)) than other applied treatments either or non-stress conditions. Furthermore, exogenous also reduced amounts hydroxyl radicals (OH), superoxide anions (O2), hydrogen peroxide (H2O2), lipid peroxidation experiencing deficit. contrast, led to an increase activity antioxidant enzymes peroxidase (POX), ascorbate (APX), glutathione (GR), catalase (CAT), dismutase (SOD). Overall, our findings indicate beneficial silicon NPs, particularly managing negative, harmful impacts soil plants.

The growing interest in the use of zinc oxide nanoparticles (ZnO NPs) agriculture creates a risk soil contamination with ZnO NPs, which can lead to phytotoxic effects on germinating seeds and seedlings. In present study, susceptibility seeds/seedlings pea wheat NPs various sizes (≤50 ≤100 nm) applied at concentrations range 100–1000 mg/L was compared. Changes metabolic profiles seedlings were analyzed by GC GC-MS methods. size-dependent harmful effect seedling’s growth revealed. more toxic (50 lowest concentration (100 mg/L) caused 2-fold decrease length roots. peas, root elongation slowed down 20–30% only 1000 NPs. response common for all tested cultivars wheat, significant increase sucrose (in roots shoots) GABA roots). seedlings, an increased content metabolites involved aspartate–glutamate pathway TCA cycle (citrate, malate) found, while total amino acids tissues) malate roots) decreased. Moreover, products starch hydrolysis (maltose glucose) endosperm indicates disturbances mobilization.

Abstract Food crops are attacked by microbial pathogens and insect pests, leading to significant yield reductions economic losses. Conventional disease diagnosis management approaches often fail provide rapid eco-friendly solutions. In the current situation, nanomaterials (NMs) serve a valuable role in both managing emerging monitoring overall plant health. Nanotechnology has transformed biotechnology industry including agriculture with specific applications such as nano-fungicides, nano-bactericides, nano-pesticides. This review focuses on use of various nanomaterials, inorganic materials Ag, ZnO, CuO, CeO, well carbon-based nanoparticles, nanotubes, nanowires, nano-capsules.
