Abstract
The biological effects of low concentrations of magnetic fluid were studied on sunflower seedlings germinated in controlled laboratory conditions. Biocompatible magnetic fluid, based on magnetite stabilized with tetramethyl ammonium hydroxide, was supplied daily for five days to freshly germinated plantlets in aqueous solution (dilutions: 20-40-60-80-100 microl/l). Green tissue was used to extract chlorophylls, carotenes and nucleic acids in specific selective solvents. Shimadzu UV-VIS spectrophotometer was utilized to measure light extinction to the wavelengths required in the frame of Meyer-Berthenrath's and Spirin's methods. Possible biotechnological tool in plant growth conducting was presumed on the basis of biocompatible magnetic fluid.
