Ultrastructural Changes in Fusarium Oxysporum F. Sp. Tulipae Hyphae Treated in Vitro with Allium Fistulosum Plant Extract
نویسندگان
چکیده
The experimental study proves in vitro antifungal activity of Allium fistulosum plant extract against Fusarium oxysporum f.sp. tulipae pathogen. The main purpose was to establish, by agar-dilution assay, the minimum inhibitory concentration (MIC) of the plant extract (140 μl/ml), compared to that of allicin (160 μl/ml) and fluconazole (100 μl/ml). The ultrastructural changes in hyphae treated with plant extract in MIC were also investigated by means of transmission electron microscopy. The ultrastructural changes consisted in irreversible alterations of cytoplasm and cell wall, compared to the control hyphae.
