Fig. 2From: Host plants directly determine the α diversity of rhizosphere arbuscular mycorrhizal fungal communities in the National Tropical Fruit Tree Field GenebankThe AM colonization frequency (F, black bar), colonization density (M, red bar), arbuscular abundance (A, green bar) and spore density (blue bar) for 12 kinds of minor tropical fruit trees in the National Tropical Fruit Tree Field Genebank. Data are shown as the means of 5 replicates with standard errors. For the same index, the same lowercase letters on the bar indicate that there are no significant differences between the two plant species (P < 0.05). The normality test and homoscedasticity test results of the 3 mycorrhizal colonization indices are listed in Additional file 4: Table S1. The abbreviations corresponding to the 12 plants are documented in the Materials and methods sectionBack to article page
