The growth–promoting effect of B. polymyxa ZYPP18 on wheat seedlings. (A) wheat seedlings grown in the Hoagland nutritional fluid with ZYPP18 or different contents of fermentation filtrate of ZYPP18; (B–I) the growth–promoting effect when treated with ZYPP18 or different contents of fermentation filtrate. (B) Longest root length of wheat, (C) Leaf length; (D) Leaf width; (E) Stems diameter; (F) Longest root length of wheat; (G) Total root length; (H) Root surface; (I) Root volume. Bar diagrams represent the mean of five replicates. Error bars indicate the standard deviation (SD) of the five replicates. Bar diagrams marked with “*” indicate significant differences between the treatment and CK (p < 0.05).
