Аннотация: We have studied the possibility of the creation of a highly effective universal stimulating preparation for presowing treatment of seeds of various grain crops on the basis of a sorption-stimulating preparation(SSP), consisting of calcium bentonite (CB), humate (H), brewery yeast autolysate (BYA), and gibberellin (Gibb). The use of some nonionic surfactants as the preparation components results in the disintegration of bentonite aggregates into individual montmorillonite particles and in an increase in the active surface of the sorption complex. This enables a 1.5-time rise in the SSP efficiency by increasing the gibberellin concentration. As a result, we have obtained a five-component substance (SSP-5), including CB, H, BYA, Gibb, and PEG. Its efficiency for spring wheat of the cultivar Liza on soddy-podzolic soil is 56%. The introduction of other biologically active substances into the preparation in order to compensate their possible lack in seeds shows that they stimulate some seeds but the general effect on other ones is reduced. It may be assumed that the creation of a universal preparation, which would be highly effective for seeds of all crops, is not possible.Gibberellin stimulates seed development much more often than other phytohormones, so we tested the SSP-5 effect on seeds of different crops and cultivars. It is revealed that this preparation is effective for seed stimulation in most cases, but its efficiency significantly varies.
