The effect of nanoparticles of biogenic ferrihydrite on the development of Lepidium sativum L.

Abstract

Abstract The basis of the study was the assumption that the nanoparticles of biogenic ferrihydrite exhibit biological activity in relation to plant organisms, which can be used in the cultivation of agricultural crops. The research studied the effect of nanoparticles of biogenic ferrihydrite on the development of seeds and seedlings of Lepidium sativum. Structural indicators were studied: masses of the aerial and root parts, linear dimensions of the above ground and root parts of seedlings. The activity of the photosynthetic apparatus was assessed by the relative index of the delayed fluorescence of chlorophyll seedlings of watercress. The germination energy and germination of seeds were investigated. The most pronounced effect of nanoparticles is registered in the increase in the total phytomass of seedlings and the length of the above ground part. A slight decrease in the photosynthetic activity of watercress sprouts was noted. The effect of nanoparticles of biogenic ferrihydrite on seed germination was not manifested.
