Effects on Glomus mosseae Root Colonization by Paenibacillus polymyxa and Paenibacillus brasilensis Strains as Related to Soil P-Availability in Winter Wheat
Figure 6
Non-linear regression analysis showing a significant positive correlation () between total P-content in wheat plants and mycorrhizal fungal root colonization, in combination with all P. polymyxa strains (B1–B4) at harvest (15 weeks). The untreated control without added microorganisms (no AMF colonization) is included. Other treatments were omitted as they did not significantly affect total P-content. Black circles represent strains added at a concentration of 106 bacterial cells 10 g−1 of seeds, whereas grey circles correspond to added amounts of 108 bacterial cells 10 g−1 of seeds. Error bars represent the standard error of the mean.
