The effect of the 1,2,3-triazolo[5,1-b][1,3,4]thiadiazines on Solanum lycopersicum L. seed germination

摘要

In recent years chemical pesticides are being replaced by environmentally friendly and universal means of plant protection that are able to exert a complex effect on the plant (stimulate growth and development, improve metabolic processes, develop resistance to pathogens, etc.). The effect of new synthetic growth regulators of the 1,2,3-triazolo[5,1-b][1,3,4]thiadiazine class and trade phytohormones (6-BAP, GA and TDZ) on the growth processes, growth energy and vitality of tomato seeds, as well as morphological parameters of seedlings was researched in this article. It was revealed that the effect of synthesized compounds on seed vigor and viability of seedlings are superior to commercial phytohormones. In the early stages of germination the seed vigor of tomato seeds treated with the compounds TT1-TT5 were superior to one in treatments with phytohormones and in control experiment. As a result of the experiment, the most viable seedlings were formed into the treatments TT1, TT2 and TT3 (in all studied concentrations).Tomato seedlings treated with 6-BAP and GA at a concentration of 5 mg L -1 produced the worst results.
