Effects on Glomus mosseae Root Colonization by Paenibacillus polymyxa and Paenibacillus brasilensis Strains as Related to Soil P-Availability in Winter Wheat

Figure 4

Percentage of AM fungal root colonization at harvest (15 weeks) in triplicate root samples with different inoculates of paenibacilli strains (B1–B4 and PB177) and Glomus mosseae. Two inoculation doses of 10⁶ and 10⁸ bacterial cells 10 g⁻¹ of seeds were applied. The control was only inoculated with G. mosseae. The same letters above the bars indicate treatments without significant differences (𝑃>.05). Error bars represent the standard error of the mean.
