Вплив кармоїзину на енергію проростання та лабораторну схожість насіння сої

Abstract

The increase in demand for bulk forms of bacterial fertilizers made on the basis of active nitrogen-fixing bacteria microorganisms strains determines the search for ways to control the quality of applying biological preparations to seeds. There are relevant studies on the possibility of using coloring agents for this purpose, selected among compounds of a chemical nature that are not toxic to seed. Therefore, the aim of the work was to investigate the influence of different concentrations of karmoizin on the germination energy and laboratory germination of soybean seeds (according to the current DSTU), which is proposed as a dye-identifier of the quality control of seed treatment with solid-phase bacterial preparations. As a result of the studies, it was found that there is no negative effect of the synthetic dye karmoizin in concentrations of 0 , 5 and 1 , 0% on the germination energy and laboratory germination of soybean seeds of varieties Almaz and Vasylkivska. Insignificant inhibition of growth processes was noted in the variants with treatment of soybean seeds of Vasylkivska variety of dye solutions used, as a consequence of root length in 5 and 8-day seedlings was by 3,4-10,2% less compared to the control. Moreover, the obtained data indicate the absence or weak level of phytotoxicity of the synthetic dye karmoizin on the germination of soybean seeds of varieties that belong to different ripeness groups.
