LIGHT SPECTRUM EFFECTS ON THE PIGMENT CONTENTS IN LEAVES OF SPROUTS OF WHEAT SEEDS TREATED WITH IRON NANOPARTICLES

Journal Title: Nature & Science - Year 2023, Vol 5, Issue 5

Abstract

In the presented article, the effect of iron oxide (Fe2O3) nanoparticles on the pigment content in the leaves of wheat seedlings in different light spectra (white, red, and blue) was studied. Wheat seeds were initially kept in a suspension solution of iron oxide nanoparticles 20-40 nm in size for 3 hours and planted in pots. The process of germination and development of seedlings took place in the dark in a phytatron for growing plants in laboratory conditions. Samples were taken from the leaves of 7-day-old seedlings. The leaves of seedlings obtained from treated and untreated seeds with iron nanoparticles were irradiated with conventional white, red and blue light for 90 minutes and then grown again in the dark for 3 days. It can be seen from the experimental results that the pigment composition of seeds treated with iron oxide nanoparticles varies depending on the spectral composition of light. It turned out that iron oxide nanoparticles have a better effect on the synthesis of chlorophyll b (Chlb) pigment under red light, while under blue light the synthesis of both chlorophyll a (Chla) and Chlb slows down, in all cases the synthesis of carotenoids is weakened.
