Botrytis cinerea can cause grey mould and seriously affect the commercial value of grapes. An artificial inoculation trial was done using table grape ‘Red Globe’ (Vitis vinifera L.). Grape berries were treated either with ultrapure water or 600, 400, 200 times dilution of wood vinegar (WV), followed by inoculation with B. cinerea suspension after 24 h. Disease incidence (DI), disease severity (DS), malondialdehyde (MDA) and hydrogen peroxide content and activities of peroxidase, ascorbate peroxidase, superoxide dismutase, polyphenol oxidase, chitinase, and β-1,3-glucanase were determined every two days during B. cinerea infection. Compared with the positive control group, WV treatment significantly reduced the DI and DS of grapes infected with grey mould. WV significantly decreased the amount of hydrogen peroxide and MDA and promoted the accumulation and expression of antioxidant enzyme in grapes. These results suggested the efficacy of WV treatment in improving the resistance of ‘Red Globe’ grapes to grey mould and in mitigating harm caused by oxidative stress.

灰葡萄孢可引起灰霉病并严重影响葡萄的商业价值。使用食用葡萄“ Red Globe”（Vitis vinifera L.）进行了人工接种试验。葡萄浆果用超纯水或木醋（WV）的600、400、200倍稀释液处理，然后在24小时后接种灰葡萄芽孢杆菌悬浮液。在此期间每两天测定一次疾病发生率（DI），疾病严重程度（DS），丙二醛（MDA）和过氧化氢含量以及过氧化物酶，抗坏血酸过氧化物酶，超氧化物歧化酶，多酚氧化酶，几丁质酶和β-1,3-葡聚糖酶的活性灰葡萄孢感染。与阳性对照组相比，WV处理显着降低了感染了灰色霉菌的葡萄的DI和DS。WV显着减少了葡萄中过氧化氢和MDA的含量，并促进了抗氧化酶的积累和表达。这些结果表明WV处理在提高“红地球”葡萄对灰霉病的抵抗力和减轻由氧化应激引起的伤害方面的功效。
