Özet
In this study, chemical compositions and antifungal activities of different blended essential oils obtained from fennel (Foeniculum vulgare Mill.) and laurel (Laurus nobilis L.) were investigated against P funerea in vitro condit ions. (teal compositions of essential oils were determined using GC-MS analysis. Antifungal volatile phase effects of different concentrations of essential oils mixtures were determined on inhibition of mycelial growth and conidial germination in vitro conditions. The effect of most effective concentrations of essential oil mixtures on the morphology of fungal hypha and con idia were also investigated using light microscope. GC MS analysis of essential oils revealed that eucalyptol (52.88%) and trans-anethole (81.55%) were the major components of laurel and fennel essential oils. Individual use of fennel and laurel essential oils were found to completely inhibit mycelial growth at 20.0 and 25.0 mu l petri(-1) concentrations, respectively. Dual blending fennel/laurel essential oil mixtures showed synergistic antifungal activity on inhibition of mycelial growth and conidial germination. By blending fennel and laurel essential oils at. proportion of 3:1, antifungal activities were significantly increased that complete mycelial growth and conidial inhibition were recorded at. relatively lower concentration (10 mu l petri(-1)). Microscopic observations on hyphae, exposed to volatile phase of the most efficient concentrations of essential oil mixtures, revealed considerable structural deformations such as cytoplasmic coagulation, vacuolization and protoplast leakage from fungal hyphae and conidia. The results showed that blending of fennel and laurel essential oils. which have synergistic antifungal effects, might be used as an effective bio fungicide in management of fungal plant disease agents.
