Abstract: The article presents data on the positive effect of zinc salts (sulfate ZnSO4 and chloride ZnCl2) and the combined application of zinc salts with the microbiological preparation Phytosporin-M, containing living symbiotic bacterial cultures of Bacillus subtilis with biofungicidal properties, on lentil seeds of Redcliff variety. The test method was a laboratory germination of the seeds between layers of paper in growth chambers according to the standard method at a constant temperature of 25 ºC in a thermostat. In the presence of zinc salts, the values for the mean length of the roots increased by up to 23-40 % and for the seedlings by up to 34-45 % as well as for the wet and dry weight of 50 roots by up to 20-22 % and for the seedlings by up to 35-41 %. The maximum for the root growth parameters was observed at a concentration of 30-50 mg/L Zn2+, for the seedling parameters – at 70 mg/L Zn2+. Practically at all concentrations of zinc ions in aqueous solution, a more pronounced stimulation of root growth was observed with the application of ZnCl2, and a stimulation of seedling growth – ZnSO4. The positive effect of Zn2+ions was also shown on the background of Phytosporin-M, which manifested itself in the stimulation of axial organ development. According to the results of the experiments, the optimum concentration of Zn2+ is 30-70 mg/L, and in complex with Phytosporin-M about 30 mg/L for chloride and 30-90 mg/L for sulfate.
