摘　　要：[Objectives]The paper was to analyze the structure of the culturable bacterial communities in healthy areca palms and those affected by yellow leaf disease(YLD).[Methods]The quantification and isolation of culturable bacteria present in the leaves,roots,and rhizosphere soil of both healthy areca palms and those exhibiting symptoms of YLD within the same orchard were conducted.Furthermore,a differential analysis of the bacterial community structure was conducted.[Results]The bacterial count was observed to be greater in healthy areca palm samples compared to those exhibiting disease symptoms.Furthermore,the diversity of bacterial species in healthy areca palm samples surpassed that found in diseased samples.Notably,the bacterial genera that exhibited significant differences between healthy and diseased areca palms included Bacillus velezensis,Paenibacillus validus,Alcaligenes faecalis,Burkholderia territorii,Pseudomonas aeruginosa,Bacillus amyloliquefaciens,etc.[Conclusions]This study may offer data support and technical guidance for the effective prevention and control of YLD in areca palm in the future.
