Резюме: An important characteristic of tobacco seeds is their different quality caused by biological or physiological reasons. This different quality is due to the different conditions of the formation and maturation of seeds in seed capsules of each inflorescence. One method reducing the different quality of seeds is topping of inflorescences. Topping of inflorescences is the practice of topping a part of the inflorescence (late flowers and immature seed capsules). Topping is mainly performed manually but it is also possible by treatment with chemical substances. The substances used so far are old and suspended from production or prohibited from use and the need for biological/organic production of tobacco seeds makes it necessary to find and use biological tools for topping of tobacco inflorescences. The purpose of the research is to study the potential of using the biopreparation VVH 86086 as a biological tool for topping of tobacco inflorescences.
