The most common fungal diseases of Vitis vinifera are powdery mildew (Erysiphe necator (Schw.) Burr.), grey mould (Botrytis cinerea Pers.) and downy mildew (Plasmopara viticola (Berk. and Curt.) Berk. and de Toni). Knowledge about the concentration of their spores in the atmosphere of the vineyard is important in order to ascertain the fungal load in the vineyard during the reproductive vine cycle. An aerobiological study was conducted in three vineyards across Europe: in North-Western Spain (Cenlle), South Spain (Montilla) and South-Eastern Poland (Rzeszów). During 2016, three Hirst-type spore traps sampled the airborne particles in each vineyard during the reproductive cycle of grapevine. The main goal of this study was the analysis and comparison of the spore concentrations in the three studied viticultural areas using different statistical tools. The most abundant spores in the vineyards atmosphere were Erysiphe necator. The highest fungal spore concentrations belonged to the North-western Spain zone, due to rainfall and temperature conditions were optimal for mould development in this area. In South Spain and South-eastern Poland, the daily spore peaks took place before than North Spain spore peaks. Average temperature, relative humidity and rainfall were the principal factors affecting the spore concentration in all zones. Redundancy Analysis showed high correlation between meteorological parameters and fungal spore concentrations.

来自不同生物气候区的三个欧洲葡萄园的空气传播真菌植物病理孢子评估

葡萄最常见的真菌病害是白粉病 (Erysiphe necator (Schw.) Burr.)、灰霉病 (Botrytis cinerea Pers.) 和霜霉病 (Plasmopara viticola (Berk. and Curt.) Berk. and de Toni)。了解其孢子在葡萄园大气中的浓度对于确定葡萄藤生殖周期期间葡萄园中的真菌负荷很重要。在欧洲的三个葡萄园进行了一项空气生物学研究:西班牙西北部 (Cenlle)、西班牙南部 (Montilla) 和波兰东南部 (Rzeszów)。2016 年,三个 Hirst 型孢子捕集器对葡萄树繁殖周期中每个葡萄园的空气传播颗粒进行了采样。本研究的主要目标是使用不同的统计工具分析和比较三个研究葡萄栽培区的孢子浓度。葡萄园空气中最丰富的孢子是白粉病菌。最高的真菌孢子浓度属于西班牙西北部地区,因为降雨和温度条件是该地区霉菌发展的最佳条件。在西班牙南部和波兰东南部,每日孢子高峰出现在西班牙北部孢子高峰之前。平均温度、相对湿度和降雨量是影响所有区域孢子浓度的主要因素。冗余分析显示气象参数与真菌孢子浓度之间存在高度相关性。最高的真菌孢子浓度属于西班牙西北部地区,因为降雨和温度条件是该地区霉菌发展的最佳条件。在西班牙南部和波兰东南部,每日孢子高峰出现在西班牙北部孢子高峰之前。平均温度、相对湿度和降雨量是影响所有区域孢子浓度的主要因素。冗余分析显示气象参数与真菌孢子浓度之间存在高度相关性。最高的真菌孢子浓度属于西班牙西北部地区,因为降雨和温度条件是该地区霉菌发展的最佳条件。在西班牙南部和波兰东南部,每日孢子高峰出现在西班牙北部孢子高峰之前。平均温度、相对湿度和降雨量是影响所有区域孢子浓度的主要因素。冗余分析显示气象参数与真菌孢子浓度之间存在高度相关性。相对湿度和降雨量是影响所有区域孢子浓度的主要因素。冗余分析显示气象参数与真菌孢子浓度之间存在高度相关性。相对湿度和降雨量是影响所有区域孢子浓度的主要因素。冗余分析显示气象参数与真菌孢子浓度之间存在高度相关性。
