Abstract

The influence of three biostimulants (Saprogum K, Saprogum NH4, Humat K), made on the basis of sapropel and peat, in the recommended dose, on the germination rate of seeds, growth of primary roots and cytogenetic indices of the apical meristem of Allium cepa are studied. All investigated biostimulants stimulate seed germination and growth of onion roots, but only when used Humate K and Saprogum K to differences with the control was statistically significant. The studied drugs stimulate the proliferative activity of the meristem in varying degrees. The use of Saprogum NH4 caused a delay in the mitotic cycle at the prophase stage. All the studied biostimulants in the tested concentration do not have a mutagenic effect according to the results of an ana-telophase test.
