Abstract
Rhizopus stolonifer is the major cause of soft rot in peaches, which leads to rapid decay and shortens the shelf life. In this study, we investigated the inhibitory mechanism of cinnamon essential oil (CEO) against R. stolonifer, evaluated its control efficacy of soft rot of peaches. The results showed that CEO treatment damaged the cell membrane of R. stolonifer, resulting in a high increase in extracellular conductivity and protein content. CEO causes the mycelium to crumple, as well as plasmalemma wall separation, the ablation and absence of some organelles. CEO also increased the contents of malondialdehyde (MDA) and hydrogen peroxide (H2O2), and the accumulation of reactive oxygen species (ROS) of R. stolonifer, thus inhibiting the growth of R. stolonifer. In addition, we found that 0.8 mL L−1 CEO fumigation significantly reduced the incidence of soft rot in peaches without any adverse effect on fruit quality. Therefore, our findings provide theory and scientific guide for the application of CEO in controlling soft rot of peaches in postharvest storage. CEO could be used as a natural fungicide to reduce fungal decay in fruits.
匍匐茎根瘤菌是桃子软腐病的主要病因,它会导致桃子迅速腐烂并缩短货架期。本研究探究了肉桂精油(CEO)对 R. stolonifer 的抑制机制,并评估了其对桃子软腐病的防治效果。结果表明,CEO 处理会破坏 R. stolonifer 的细胞膜,导致细胞外传导性和蛋白质含量增加。CEO 会导致菌丝皱缩,以及质膜壁分离、某些细胞器消融和缺失。CEO 还会增加 R. stolonifer 的丙二醛(MDA)和过氧化氢(H2O2)含量,增加活性氧(ROS)的积累,从而抑制 R. stolonifer 的生长。此外,我们还发现,0.8 mL L-1 CEO 熏蒸剂可显著降低桃子软腐病的发病率,且不会对果实质量产生任何不利影响。因此,我们的研究结果为应用 CEO 控制桃子采后贮藏中的软腐病提供了理论和科学指导。CEO 可以作为一种天然杀真菌剂来减少水果的真菌腐烂。
