摘要

Plant growth promoting microorganisms (PGPMs) represent an environmentally sustainable alternative to chemical fertilizers, yet their application in soilless cultivation systems remains insufficiently studied. This study investigated the individual effects of four PGPMs, Bacillus subtilis, Pantoea agglomerans, Serendipita indica, Funneliformis mosseae, and three phosphorus concentrations (10, 20, and 40 mg L−1) on growth, nutrient uptake, and essential oils (EOs) production in hydroponically grown basil (Ocimum basilicum L.). Results indicated that reduced phosphorus availability restricted biomass production, whereas PGPM inoculation significantly enhanced plant growth and improved shoot and root P and K accumulation (P ≤ 0.01). EOs content was strongly influenced by both microbial inoculation and P level: S. indica and P. agglomerans at 40 mg L−1 P increased EOs percentage four- and three-fold, respectively, compared with controls. Chemical profiling revealed notable shifts in EOs composition, with estragole as the predominant component. Inoculation with F. mosseae at 40 mg L−1 P yielded the highest estragole concentration (43.7%), while B. subtilis under the same condition maximized δ-cadinene, β-farnesene, α-bergamotene, and γ-cadinene levels. These findings highlight the potential of PGPMs to improve phosphorus use efficiency and enhance both yield and phytochemical quality in hydroponic basil, providing a practical and sustainable approach for reducing fertilizer inputs in soilless cultivation systems.
