The widespread application of chemical fertilizers and pesticides has resulted in environmental pollution. With the growing emphasis on ecological agriculture traditional Chinese medicine, microbial are increasingly recognized for their potential. aim this study is to investigate effect inoculating nitrogen-fixing bacteria soil (yellow loam, river sand, organic fertilizer a 2:1:1 ratio) Fritillaria taipaiensis, with focus leaf changes terms physiological parameters, antioxidant enzyme activity, corresponding gene expression levels. experiment involved three bacteria, namely Rahnella aquatilis, Pseudomonas chlororaphis, Paenibacillus stellifer, total eight treatment groups. objective was assess how these bacterial treatments influenced photosynthetic characteristics, pigment content, both activities leaves F. taipaiensis. experimental results demonstrated statistically significant reductions (p < 0.05) malondialdehyde (MDA) content stomatal limitation value (LS) taipaiensis under conditions relative control group (CK). most substantial decreases were observed dual-inoculation R. aquatilis P. stellifer (N5), showing 38.24% 20.94% MDA LS compared CK values. Additionally, area, thickness, stem plant height, soluble sugars, proteins, proline levels, superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) exhibited varying degrees increase. Compared group, SOD, POD, CAT N5 increased by 141.06%, 160.59%, 106.23%, respectively. patterns corresponded trends respective activities. Pearson correlation analysis further that area net rate (Pn) significantly correlated respect activities, as well In conclusion, inoculation improved growth stress tolerance combined yielding effective results. This establishes different rhizosphere either individually or combination, influence biochemical protective systems These findings provide theoretical foundation selection biofertilizers artificial cultivation highlight potential medicinal materials.
