Do grupy środków nazywanych biostymulatorami stosowanymi w ogrodnictwie czy rolnictwie należą preparaty zawierające w swoim składzie ekstrakty z alg morskich, roślinne oraz zwierzęce hydrolizaty białkowe, związki humusowe, korzystne bakterie i grzyby oraz ko­rzystne mikroelementy. Celem niniejszego opracowania jest przedstawienie efektów działania biostymulatorów należących do różnych grup. Efekty te obejmują zarówno wzrost i plonowanie roślin, poprawę ich odżywienia, wpływ na zawartość składników bioaktywnych, ochronę przed stresem spowodowanym czynnikami abiotycznymi (np. suszą czy niską temperaturą) lub biotycznymi (np. patogenami bakteryjnymi lub grzybowymi). Stosowanie biostymulatorów stanowi ważny element nowoczesnej uprawy roślin ogrodniczych, która dąży do poprawy wzrostu, plonowania i jakości roślin, przy jednoczesnym ograniczeniu syntetycznych agrochemikaliów.

The group of substances known as biostimulants used in horticulture and agriculture includes preparations containing seaweed extracts, plant and animal protein hydrolysates, humic compounds, beneficial bacteria and fungi, and beneficial elements. The aim of this study is to provide a broad overview of the effects of biostimulants belonging to the above-mentioned groups. These effects include plant growth and yield, improved nutrition, influence on the content of bioactive components, and protection against stress and bacterial and fungal pathogens. The use of biostimulants is an important element of modern horticultural plant cultivation, which aims to improve plant growth, yield and quality while reducing the use of chemicals.
