“…Laboratory germination in the first case was 83%, in the second -97%. Plants developed better under the biological preparation influence than in the intact control: the length of seedlings was 8.05 cm longer and roots 4.26 cm longer (Subbotin et al, 2016).…”

The microbiota of winter wheat seeds from the North-East of Ukraine was studied by a biological method. Its considerable variability is established over three years (2017–2019). The effect of the treatment agents on most microorganisms of wheat seed microbiota in Ukraine, rather than on its genera and species, is shown. It has been proven that fungicides deleted some species and did not affect the development of others. Chemicals replaced some species or genera of fungi with others or even other microorganisms. Biological seed treatment (Phytosporin-M) has caused less microbiota change than chemical treatment (Maxim 0.25 FS, Rostock, Kinto Duo). Fungicides have replaced the dominance of Alternaria spp. (2017 – 57.8%, 2018 – 63.5%) for the dominance of yeast (Rostock – 54%) and Aureobasidium pullulans (Maxim 0.25 FS – 84.2%) in 2017, bacteria (Maxim 0.25 FS – 72.3%, Rostock – 53.8%) – in 2018. A. pullulans dominated in the microbiota of winter wheat seeds in 2019. The highest amount of A. pullulans was noted for the treatment of seeds by Phytosporin-M (85.9%). The biological seed treatment reduced the amount of Nigrospora spp. and Alternaria spp. Several times (3 and 5, respectively), chemical agents did not give Nigrospora spp. germination reduced the amount of A. pullulans, Alternaria spp. in 2019. Maxim 0.25 FS, Rostock 50%, and Kinto Duo delayed seed germination and seedling development on agar medium and soil, whereas Phytosporin-M – on the contrary, promoted the growth of seedlings and significantly exceeded control.

“…Using bacterial cultures from this collection, the research was carried out to study the influence of "relict" microorganisms on the morphophysiological, biochemical and cytogenetic indicators of modern biological objects of different organization levels from unicellular organisms to higher plants and animals. When testing several bacterial strains from permafrost on cultivated plants, it was shown that about 30% of them have a positive effect on the morphophysiological, biochemical and adaptive parameters of cultivated cereals and potatoes [14][15][16][17][18][19][20].…”

The effect of secondary metabolites of bacteria from permafrost rocks on the in vitro morphophysiological parameters of potato microplants has been studied. Microplants of Zhukovsky ranniy potato variety were used as the object of the study. The experimental results indicate that when potato microplants are grown in vitro together in the Murashige-Skoog nutrient medium with the bacteria metabolites of the Bacillus cereus 9-08-CH9 and Achromobacter spanius 10-50TS2 strains introduced at the grafting time at a dose of 250 μl, they have the highest inhibitory effect. Secondary metabolites of these bacterial strains have a significant increase in the number of internodes at all stages of plant cultivation, which can accelerate the in vitro replication of material for original potato seed production. Metabolites of the bacterial strain Bacillus cereus 875TS in the indicated concentrations cause growth inhibition and delay in the development of microplants’ root system at the initial cultivation stages.
