Enhanced Growth in Cucurbita maxima Seedlings Inoculated with Endophytic Fungi isolated from Rhizophora racemosa Rhizosphere

Endophytic fungi are considered an eco-friendly and bio-safe alternative to increase agricultural productivity. The study objectives were to isolate and identify endophytic fungi from the roots of Rhizophora racemosa and to assess their effect on the growth of Cucurbita maxima plants. Molecular identification of the endophytic fungal isolates revealed five fungal species: Aspergillus aculeatus, Aspergillus fumigatus, Fusarium equiseti, Penicillium citrinum, and Talaromyces albobiverticillius. A. aculeatus induced the best improvement rate of plant development with an increase of shoot length (۱۵۹ %), petiole length (۱۷۱%), internode length (۱۵۵%), leaf number (۱۳۳%) and leaf area (۱۴۹%)at ۸۴ days after the fungal treatment. This research highlights the importance of A. aculeatus, which can be an eco-friendly bio-fertilizer that can enhance the production of Cucurbita maxima and improve the agricultural sector. To confirm its effectiveness, experiments must be conducted in fields and greenhouses.
