Abstract
Copper oxide nanoparticles (CuO NPs) are emerging as promising tools in plant biotechnology, particularly for improving tissue culture techniques. However, their application in tomato micropropagation is still not well understood. This study explores the impact of CuO NPs on the in vitro regeneration of Solanum lycopersicum L. cv. Sankranti, aiming to determine their effectiveness in promoting plant growth and development under controlled conditions.CuO NPs were synthesized by calcining copper(II) complexes of (Z)-N’-(3-ethoxy-2-hydroxybenzylidene)benzohydrazide, prepared from different copper salts: CuSO₄·5H₂O, CuCl₂·2H₂O, and Cu(NO₃)₂·3H₂O. These complexes were characterized using FT-IR, UV-Vis spectroscopy, mass spectrometry, thermogravimetric analysis (TGA), magnetic studies, and molar conductance. The nanoparticles were further analysed using FT-IR, UV-Vis, PXRD, SEM, and TEM to confirm their structure and morphology. To evaluate their biological effect, CuO NPs were added to Murashige and Skoog (MS) medium at varying concentrations (0.02, 0.2, and 2.0 mg/L) and tested on tomato nodal explants. Statistical analysis using one-way ANOVA confirmed that these enhancements were significant (p < 0.05) when compared to the control group. Overall, this study highlights the potential of CuO NPs, particularly at optimized concentrations, to serve as beneficial micronutrient additives in plant tissue culture. These results support their future application in improving micropropagation efficiency for tomato and possibly other high-value crops.
期刊介绍:
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
