EFFECT OF LACTOBACILLUS PLANTARUM AND BACILLUS ATROPHAEUS ON GERMINATION OF WHEAT SEEDS AND SEEDLINGS GROWT

Aim. Study of the effect of bacteria of the strains Lactobacillus plantarum ONU12, ONU311 and Bacillus atrophaeus ONU528 on germination of wheat seeds and growth characteristics of seedlings. Methods. Inoculation of surface sterilized seeds with the diluted cultures. The inoculated seeds were brought into wet cameras, and after germination the measurement of seedling growth characteristics were done. Results. The treatment by L. plantarum ONU311 resulted in increase of the length of seedlings roots in 31% as compared with the control and stimulation effect on the length of height was 48%. The mixture of the strains L. plantarum ONU12 and ONU311 increased the length of roots and height of the seedlings in 41.1 and 52.4% accordingly, and seeds germination – in 25%. The treatment of wheat seeds by bacteria B. atrophaeus ONU528 resulted in increase of mean length of roots in 39.7% and height of seedlings in 45% as compared with the control. Conclusions. Bacteria L. plantarum, B. atrophaeus and their mixtures had the stimulation effect both on roots and height of wheat seedlings. The influence of lactic acid bacteria depended both on the strains and concentrations of bacterial cells.
