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.
