Abstract
The present research was undertaken to study the antifungal activities of Origanum onites L. and Ziziphora clinopodioides L. essential oils against three different isolates (M1-5, M2-1 and M3-5) of Botrytis cinerea (in vitro tests) and to investigate the vapor contact impacts on fungus and strawberry fruit quality (in vivo tests). Antifungal activities of these oils were tested by following the poisoned food technique at four different concentrations (0.25, 0.50, 1.00 and 2.00 mL/L) against B. cinerea. In vitro studies suggested that the 0.50 mL/L and 1.00 mL/L doses of O. onites and 1.00 mL/L and 2.00 mL/L doses of Z. clinopodioides provide high mycelial growth inhibition, 85.29–94.12% and 39.12–94.12%, respectively, by direct addition to food. Thus, these doses were tested in in vivo conditions, as a vapor contact treatment against two isolates (M1-5 and M3-5) of B. cinerea inoculated on strawberry cv. Camarosa fruits. Results showed that both O. onites and Z. clinopodioides essential oils have a moderate to high impact on the prevention of gray mold. The oils were also found to have a slight to moderate impact on weight loss and the loss of soluble solids concentration. Overall, the results demonstrated that the tested oils are a potential biodegradable alternative to fungicides.
Highlights
Postharvest quality of fresh horticultural crops is significantly affected by several biological factors, including respiration, transpiration, ethylene and phytopathogens and these factors can be managed by several environmental factors, such as temperature, relative humidity, air composition, light, heat, ethylene and biomaterials
The highest mycelial growth of all isolates were obtained from the two controls after seven days of incubation
Camarosa strawberry fruits was extended to days with the combined application of of lemongrass essential oil and modified atmosphere packaging. In agreement with this lemongrass essential oil and modified atmosphere packaging. In agreement with this litliterature, the results of the current study showed that both doses of Z. clinopodioides (ZC) and higher doses erature, the results of the current showed that both of ZC and higher doses of of O. onites (OO) have very good control of study gray mold in 12 days of doses storage
Summary
Postharvest quality of fresh horticultural crops is significantly affected by several biological factors, including respiration, transpiration, ethylene and phytopathogens and these factors can be managed by several environmental factors, such as temperature, relative humidity, air composition, light, heat, ethylene and biomaterials. Postharvest decay caused by Botrytis cinerea (gray mold) is among the main causes of the postharvest losses. This necrotrophic and airborne fungus attacks more than 200 crops, mostly including pome fruits, stone fruits, grapes and berries. The disease symptoms vary widely, but most of them include soft rots accompanied with water-soaked parenchyma tissues and followed by gray masses of conidia [3]. These symptoms decay the fruits and render their marketability. The secondary metabolites of the mold (mycotoxins) have direct adverse impacts on human health [5]
