Studying the biochemical characteristics of lavender under the influence of the application of metal nanoparticles

This study was conducted in order to investigate the effect of some metal nanoparticles on some biochemical properties of lavender callus. ase in the amount of proline, soluble sugars, flavonoid and phenol. The highest amount of soluble sugars, flavonoids and phenols were obtained at the values of 8.46, 3.8, 3.02 and 79.35, respectively, in the treatment of simultaneous application of three nanoparticles. Based on the results, it was found that the content of soluble protein and the activity of catalase and peroxidase enzymes were positively affected by the application of metal nanoparticles, and the simultaneous application of iron and silver nanoparticles led to the highest amount of soluble protein at 0.2 units per gram. This was while the highest level of catalase (0.43 units/g/min) and peroxidase (0.4 units/g/min) enzymes were observed in the simultaneous application of all three nanoparticles and the simultaneous application of silver and zinc nanoparticles, respectively. Based on the results of this study, it was determined that the simultaneous application of metal nanoparticles with increasing the amount of non-enzymatic antioxidants and also increasing the activity of enzymatic antioxidants led to an increase in the health of cells and a decrease in the production of malondialdehyde, and by reducing the negative effects of oxidative stress in the plant, the conditions for An increase in the production of photosynthetic pigments is provided.
