Abstract

Determining the environmental safety of new synthetic plant growth regulators is an urgent problem. Spirocarbon derivatives were subjected to such determination by means of a specially developed system based on phytotests "germinated seeds". This system allows the values of biometric, cytological and biochemical parameters of the phytotest to determine the toxic, cytotoxic, genotoxic (mutagenic) effects and induction of molecular stress by the synthetic chemical substance being tested. This system was used to establish the biological properties of a new drug - a complex of spirocarbon with boric acid - in relation to five phytotests monocotyledons and dicotyledons plants. Phytotesting was performed in the spectrum of concentrations (10-7-10-2 mol/dm3) of this drug. It demonstrated either the absence or presence of a weak toxic effect on phytotests, which did not exceed 30%. The study showed that the plant growth regulator spirocarbon in combination with boric acid has growthregulating properties, the manifestation of which depends on the concentration of the drug and the species characteristics of plants. Only the maximum concentration (10-2 моль/дм3) of the tested drug is slightly toxic to plants. The obtained results testify to the biological efficiency and ecological safety of the synthesized drug. This allows us to recommend it for use in agricultural practice.
