Item Effect of essential oils on postharvest decay and some quality factors of peach (Prunus persica var. Redhaven )(Uludağ Üniversitesi, 2012) Mohammadi, Samane; Aminifard, Mohammad HosseinThe aim of the study was to determine the antifungal effects of the essential oils against fungal pathogen Botrytis cinerea the causal agent of grey mould disease of peach (Prunus persica L.) under in vitro and in vivo conditions. Treatments consisted of four essential oils (anise, ammi, ziziphora and cinnamon) and five concentrations (0, 200, 400, 600 and 800 μL.L-1).Results of in vitro experiment showed that all of used essential oils at all applied concentrations inhibited grey mould growth. All of these essential oils in concentration 800 μL.L-1 were without germination spores of grey mould. The essential oils application significantly decreased weight loss percentage and increased life storage fruits. Also, essential oils positively affected on postharvest quality factors including total soluble solids, titrable acidity, anthocyanin, carbohydrate content and pH value. It was observed that treated fruits with ammi essential oil at concentration 800 µL.L-1had the highest total soluble solids; titrable acidity, anthocyanin, and carbohydrate content and it had the lowest decay and acidity. Thus, these results showed that essential oils have strong impact on postharvest decay and fruit quality of peach.Item Effects of essential oils to control rhizopus stolonifer in vitro and in vivo on strawberry(Uludağ Üniversitesi, 2014-07-05) Mohammadi, Samane; Aroiee, Hossein; Aminifard, Mohammad Hossein; Tehranifar, Ali; Jahanbakhsh, VahidThe aim of this study was to evaluate the antifungal effects of essential oils (fennel, black caraway and anis) at different concentrations against the fungal pathogen, Rhizopus stolonifer, the causal agent of smooth rot disease of strawberry (Fragaria ananassa Duch.) under in vitro and in vivo conditions.The results of in vitro showed the growth of R. stolonifer was completely inhibited by the application of fennel, anis and black caraway oils at concentrations 600 and 800 ΜL.L -1 , respectively. The results of in vivo indicated that fennel, anis and black caraway oils at all applied concentrations inhibited R. stolonifer growth on strawberry fruits compared with control. Also the mentioned oils at upper concentrations showed positive effects on fruit quality characteristics like titrable acidity, total soluble solids, anthocianin content, ascorbic acid and weight loss percentage. These essential oils inhibited to infection fruits by R. stolonifer and increased life storage fruits. The present research confirms antifungal effects of these essential oils of both in vitro and in vivo on fruit postharvest.
