摘要

Fungi, ubiquitous across ecosystems, are integral to ecological balance and economic dynamics. This study delves into their significance, highlighting diverse habitats and roles in substance breakdown, food, and medication sources. The adverse effects of chemical fertilizers on soil composition and microbiome necessitate sustainable agricultural alternatives. Plant growth promoting fungi (PGPF) emerge as a solution, demonstrating systemic immunity development, phytohormone synthesis, and direct/indirect plant growth enhancement. Despite documented benefits, the impact of different PGPFs in immature soil is underexplored. Coexisting with microorganisms, especially PGPFs, induces host plant resistance and promotes eco-friendly disease management, ensuring soil fertility. PGPFs’ capacity to solubilize phosphates, generate phytohormones like Indole-3-Acetic Acid (IAA), and suppress soil pathogens underscores their multifaceted role in plant development. IAA, vital for root system augmentation and stress resistance, exemplifies PGPFs’ diverse functions. This study reveals positive PGPF interactions, including amplified root and shoot growth, enhanced chlorophyll content, and heightened induced systemic resistance. Notable PGPFs like Arbuscular Mycorrhizal Fungus, Fusarium, and Penicillium contribute to these effects. The significance lies in a comprehensive screening procedure for detecting PGPFs in soil, specifically for phosphate solubilization and IAA production. The laboratory procedure involves systematic soil sample dilution, using Pikovskaya’s agar plate assay for phosphate solubilization and Salkowski’s reagent for IAA production, offering insight for researchers and practitioners dedicated to optimizing soil fertility and enhancing crop productivity.
