In this study, an oomycete strain FQ01 of , which could cause destructive postharvest disease, was isolated. At present, chemical fungicides are the main reagents used for controlling diseases. It is necessary to find new control techniques that are environmentally friendly. The biocontrol activity of MP1861 against FQ01 was therefore investigated. Our results revealed that the volatile organic compounds (VOCs) released by the yeast strain MP1861 could inhibit the development of FQ01. The major component of the VOCs produced by the yeast strain MP1861 was identified to be ethyl acetate (70.8%). Biocontrol experiments showed that disease in tomato fruit could be reduced by 95.8% after the yeast VOCs treatment. Furthermore, ethyl acetate inhibited the mycelial growth of the oomycete strain FQ01, and damaged the pathogen cell membrane. This paper describes the pioneering utilization of the yeast strain MP1861 for biocontrol of postharvest fruit rot in tomato caused by .
在本研究中,分离出了一种能引起毁灭性采后病害的卵菌菌株FQ01。目前,化学杀菌剂是防治病害的主要试剂。有必要寻找环保的新防治技术。因此,研究了MP1861对FQ01的生防活性。我们的结果表明,酵母菌株MP1861释放的挥发性有机化合物(VOCs)可以抑制FQ01的生长。酵母菌株MP1861产生的VOCs的主要成分被鉴定为乙酸乙酯(70.8%)。生防实验表明,酵母VOCs处理后,番茄果实病害可减少95.8%。此外,乙酸乙酯抑制了卵菌菌株FQ01的菌丝生长,并破坏了病原菌细胞膜。本文描述了酵母菌株MP1861在防治番茄采后果实腐烂方面的开创性应用。
