    Plant growth stimulators are capable of enhancing both agricultural output and the rate of plant maturation, consequently improving the total crop yield and increasing their resistance to disease and adverse environmental conditions. This is why such compounds are used in the cultivation of both agricultural and ornamental plants. The aim of this work was to study the effect of ethyl 5′-(4-methoxybenzoyl)-5′,7′-dihydrospiro[cyclopentane-1,6′-[1,2,3]triazolo[5,1- b][1,3,4]thiadiazin]-3′-carboxylate on Pinus sylvestris L. seed germination. The article describes the synthesis of ethyl 5′-(4-methoxybenzoyl)-5′,7′-dihydrospiro[cyclopentane-1,6′- [1,2,3]triazolo[5,1-b][1,3,4]thiadiazin]-3′-carboxylate and the data from spectral and X-ray crystal analysis. The results of the experimental stimulation of Pinus sylvestris L. seed germination using spiro-1,2,3-triazolo[5,1-b]1,3,4-thiadiazine are given compared to the commercially available phytohormones thidiazuron and 6-benzylaminopurine. The estimation of germination, vitality, healthy seed ratio and cotyledon length indicated that the tested compound at a concentration of 0.5 mg L -1 had an effect similar to 6-benzylaminopurine: indeed, the speed of germination and fungal invasion rate exceeded the effect of 6-benzylaminopurine.
