FIGURE 3.

Differences in ear emergence times between wheat plants (Triticum aestivum cv. Trappe) growing from seeds colonized by P. phytofirmans PsJN and control seeds (A) observed in greenhouse pot experiments and in the field (B). (A) The different time points of flowering in control and PsJN-colonized plants is shown. (B) A significantly higher number of ears per square meter in the plots was observed for PsJN-plants (n = 722) as compared to control plants (n = 644) (F-test; p = 0.018). All wheat plants tested belonged to the F1 generation, derived from parent plants which were sprayed with a suspension of P. phytofirmans PsJN or sterile buffer (control).
