The primary objective of this work was to ascertain whether silicon oxide nanoparticles (SiO2-NPs) could improve the growth and volatile oil productivity under abiotic stress. The Thymus serpyllum shoots obtained in vitro were cultivated on Murashige and Skoog (MS) medium that had been strengthened with various NaCl at 0.0, 25, 50, and 100 mM. SiO2-NPs at a level of 100 mg/L were combined with sorbitol at 0.0, 15, 30, and 45 g/L or polyethylene glycol (PEG) at 0.0, 1, 2, and 4% as drought stress agents. The vegetative growth, root development, proline content, and volatile oil were measured. The maximum values of shoot number, root number, and root percentage in terms of salinity were found in the MS medium with 100 mg/L SiO2-NPs + 25 mM NaCl. The combination of 100 mg/L SiO2-NPs plus 15 g/L sorbitol produced the highest value of parameters, with the exception of shoot and root length. At 100 mM NaCl, salinity led to the greatest concentration of proline. When SiO2-NPs with PEG were applied, the shoots survived, and there was a considerable proline deposit at 100 mg/L SiO2-NPs + 2% PEG. At 100 mg/L SiO2-NPs + 30 g/L sorbitol, the largest percentage of volatile oil was found to exist, with thymol as its main constituent. [ABSTRACT FROM AUTHOR] |
