MINERAL NUTRITION OF ARONIA MELANOCARPA ELLIOT DURING IN VITRO CULTIVATION ON ARTIFICIAL NUTRIENT MEDIUM

Abstract

The research was conducted at the Biotechnology Department of the RUE «Institute for Fruit Growing» and the Institute of Physical Organic Chemistry of the National Academy of Sciences of Belarus. The chemical composition of the nutrient medium for Aronia melanocarpa Elliot plants cultivation in vitro on micropropagation and root formation stages was determined with the use of ion chromatography and atomic emission spectroscopy. Nutrient intake structure was established, ion usage difference at the various stages of in vitro growing is shown. The authors have established the significant change of ions starting ratio, increasing concentration of individual ions in the nutrient medium by the end of the cultivation, due to their uneven consumption by the plants.
