盖氏假单胞菌PG-9对苹果根系内生细菌OTU数量的影响

盖氏假单胞菌PG-9对土壤细菌OTU数量的影响见图(12)。PG-9菌株处理共得到163个OTUs，特有的为47个OTUs，CK处理共得到187个OTUs，特有的为71个OTUs。其中，PG-9菌株处理和CK处理共有的OTUs为116个。结果表明，施用盖氏假单胞PG-9处理后降低了苹果根系内生细菌群物种数量。

The impact of the endophytic bacterial alpha diversity on apple root system.

The impact on the number of operational taxonomic units (OTUs) of endophytic bacteria in apple root system.

The effect of Pseudomonas putida PG-9 on the number of soil bacterial OTUs can be seen in Figure (12). A total of 163 OTUs were obtained with PG-9 treatment, of which 47 were unique OTUs. A total of 187 OTUs were obtained with CK treatment, of which 71 were unique OTUs. Among them, there were 116 common OTUs between PG-9 treatment and CK treatment. The results indicate that the application of Pseudomonas putida PG-9 reduced the number of endophytic bacterial species in the apple root system.
