Physiological and Biochemical Parameters of In Vitro Potato Plants Cultured on Media with Manganese-Hydroxide and Copper-Oxide Nanocomposites in an Arabinogalactan Matrix
The biological activity of chemically synthesized nanocomposites (NCs) based on nanoparticles (NPs) of copper(I) oxide (NC Cu2O/AG) and manganese hydroxide (NC Mn(OH)2/AGs) based on an arabinogalactan (AG) natural polymer matrix is investigated for the development of a novel growth promoter for potato plants. Potato plants are grown on a nutrient medium, to which, instead of CuSO4·4H2O and MnSO4·4H2O salts, the corresponding NCs are added separately or in combination. It is found that NC Mn(OH)2/AGs at a concentration of 0.0132%, both individually and in combination with NC Cu2O/AG at a concentration of 0.0084%, stimulates incremental growth by 20% compared to the control in vitro potato plants. This NC enhances the growth of potato plants by elongation of the internodes and increases the biomass of the roots and aerial parts. The biomass of roots in plants, growing on a medium with two NCs, is 70% higher than in the control. Stimulation of the increase in biomass may be associated with the enhanced intensity of photosynthesis due to an increase in the amount of pigments in response to this NC. The content of carotenoids increases by 40% in response to the manganese-containing NC. Treatment with the studied NC reduces the amount of reactive oxygen species (ROS) in root tissues from 35 to 68% due to the enhanced activity of antioxidant enzymes. Catalase activity is boosted by 16 to 120% compared to the control. These data and previously obtained results suggest that the manganese NC shows considerable promise as a growth promoter in cultivated plants.
