Effects of tea tree oil fumigation on banana postharvest disease Colletotrichum musae
摘要
Abstract
The effects of natural plants extracts against banana postharvest disease Colletotrichum musae was evaluated.The antifimgal activity of 0～40μL TTO(tea tree oil) and its main components (Terpinenol-4, a-Terpineol, γ-Terpinene and 1,8-Cineole) against colony growth of C.musae in vitro and their effects on disease intensity and defense-related enzymes of banana fruits inoculated with C.musae were determined at 25℃ and 75％ relative humidity.Results showed that fumigation of TTO, Terpinenol-4 and a-Terpineol could significantly inhibit C.musae growth in vitro.In addition,the antifungal activity of TTO and its main components could be greatly enhanced with higher levels.Compared with non-treated fruits, 1.25 g/L TTO fumigation reduced lesion diameter of inoculated banana fruits, but less than 0.32 g/L Terpinenol-4 or a-Terpineol.Moreover.1.25 g/L TTO fumigation induced significant increase in peroxidase(POD), and phenylalanine ammonia-lyase(PAL), but decreased polyphenoloxidase(PPO) activity.The preliminary study suggests that TTO fumigation is feasible on fresh-keeping and increasing of disease resistance in postharvest banana fruits,meanwhile, Terpinenol-4 and a-Terpineol are primary antifungal activities of TTO.关键词
