In modern agriculture, plant-derived substances referred to as plant growth and development regulators or biostimulators are increasingly used. The aim of the research was the influence of the applied biostimulators on the concentration of glucosinolates in seeds of three morphotypes of winter oilseed rape. The research was carried out in three growing seasons at the University of Natural Sciences and Humanities in Siedlce (52 o 03'N i 22 o 33'E), Poland. The examined factors were: morphotypes of winter oilseed rape: hybrid restored with a traditional type of growth (Konkret), population (Poznaniak), hybrid restored with a semi-dwarf type of growth (PX104), II-four types of biostimulators: 1. Asahi®SL, 2. Silvit®, 3. Tytanit®, 4. control variant. The applied biostimulators had a positive effect on the feed value of the seeds in terms of glucosinolates. In all varieties and years of research, the lowest concentration of these compounds was recorded after the application of the Silvit biostimulator, while in the first year of research after the application of Silvit and in the second year after the application of Tytanit and Asahi SL biostimulators, the same content of these compounds was obtained.
