Effect of Fe۲O۳ on growth, relative water content and flavonid content of Matricaria chamomilla extract

Matricaria chamomilla is a medicinal plant belonging to Asteraceae family and has antioxidant, anti-inflammatory and anti-cancer properties. Nanoparticles have small size and high surface area which are absorbed highly by cells. Recently, nano-macro and micro nutrients are used to increase agricultural production. In this study, sterilized seeds were put in Murashige and Skoog medium containing different concentrations of Fe۲O۳ nanoparticles and transferred to the growth chamber with a ۲۵±۲ °C temperature, ۴۵% humidity and light conditions of ۳۰۰۰ lux. After ۴ weeks of culture, seedlings subjected to various biochemical and physiological analyzes. Results showed that nanoparticles at ۲۵ mg L-۱ induced seedling growth and with increasing of nanoparticle concentrations, growth parameters decreased. The relative water content showed an ۱۹.۴۶% increase at ۲۵ mg L-۱ nanoparticles compared to the control. Flavonoid content was higher in the methanolic extract of leaves than the roots and increased at ۲۵ and ۵۰ mg L-۱ compared to the control. The highest flavonoid content was observed at ۲۵ mg L-۱ which showed an ۵۰.۱۳ and ۸۴.۳۲% increase in leave and roots compared to the control, respectively. The results of this study indicated the beneficial effects of iron nanoparticles in the proper concentration on growth and flavonoid content of M. chamomilla seedlings.
