title: Effect of nutrient density on the growth processes of micro plants of native Don varieties in in vitro culture
abstract: Abstract. During microclonal propagation, agar is widely used as a thickener for solid or semi-solid nutrient media used as substrates for the regeneration and cultivation of micro plants. This component is strictly controlled and is suitable for microclonal reproduction tasks. The low turbidity of the forming gel when using agar allows to observe the development of roots, and the high strength of the gel (about 1000 g/cm2 ) allows you to use low concentrations (0.4-0.6 %). The most commonly use
