EFFECT OF LACTOBACILLUS PLANTARUM AND BACILLUS ATROPHAEUS ON GROWTH OF WHEAT SEEDLINGS

Abstract

The effect of bacteria of the strains Lactobacillus plantarum ONU 12, ONU 311 and Bacillus atrophaeus ONU 528 on growth characteristics of wheat seedlings have been studied. Inoculation of surface sterilized seeds with the diluted cultures was conducted. The inoculated seeds were brought into wet-chambers, and after germination the measurements of seedling growth characteristics were done. The treatment by L. plantarum ONU 311 resulted in increase of the length of seedlings roots in 31% as compared with the control and stimulation effect on the height of seedlings was 48%. The mixture of the strains L. plantarum ONU 12 and ONU 311 increased the length of roots and height of seedlings in 41,1% and 52,4% accordingly. The treatment of wheat seeds by bacteria B. atrophaeus ONU 528 resulted in increase of mean length of roots in 39,7% and height of seedlings in 45% as compared with the control. Bacteria L. plantarum, B. atrophaeus and their mixtures had the stimulation effect both on roots and height of wheat seedlings.
