苹果土壤真菌多样性受盖氏假单胞菌GP-9影响

Impact on alpha diversity of soil fungi in apple soil: Impact on beta diversity of soil fungi in apple soil: Differences in soil fungal community composition between different treatments can be seen in Figure 8. PC1 and PC2 explain 69.78% and 18.5% of the total variation in soil fungal communities, respectively. The distance between the PG-9 treatment and the control is relatively far, and they are located in different quadrants, indicating differences in similarity between soil fungal communities among treatments. These results suggest that the application of Pseudomonas protegens GP-9 can alter the structure of soil fungal communities.
