AMF colonization rate of continuously cropped soybeans in potted-experiments. White, gray and stripes represent samples from the CK, F, and AF groups, respectively. CK means soybean were planted the normal sterilized soil; F means soybean seeds were inoculated with F. oxysporum spore suspension; AF means soybean seeds were inoculated with F. mosseae + F. oxysporum. Note: All experiments were conducted in potted-experiments. X-axis represents which day detected the AMF colonization rate of continuously cropped soybean roots. Y-axis represents the AMF colonization rate. The data shown here are the averages for three plants under each condition and the error bars represent standard deviations. Bars subtended by the same lowercase letter do not differ significantly at p < 0.05 according to Tukey’s test
