苹果土壤细菌Beta多样性受盖氏假单胞菌PG-9影响

Translation: The impact of Apple soil bacteria Beta diversity

The inter-group differences in soil bacterial community composition under different treatments can be seen in Figure 4. PC1 and PC2 explain 56.67% and 16.65% of the total variation in soil bacterial communities, respectively. The distance between the PG-9 strain treatment and the control is relatively far, and they are located in different quadrants, indicating differences in similarity between the soil bacterial communities under different treatments. These results suggest that the application of Pseudomonas fluorescens PG-9 may alter the structure of soil bacterial communities.
