虽然真菌孢子是全年大气中始终存在的组成部分，但它们的浓度波动很大。这项工作的目的是建立真菌孢子浓度之间的相关性在波尔图和阿马雷斯和气象数据。使用体积孢子捕获器连续研究了真菌孢子的季节性分布（2005-2007年）。为了确定气象因素（温度、相对湿度和降雨量）对孢子浓度的影响，采用斯皮尔曼等级相关检验。在这两个地方，最丰富的真菌孢子是枝孢属，蘑菇，田头菇属，链格孢属和曲霉/青霉，最高浓度被发现在夏季和秋季。在本研究中，除了鬼伞属和Pleospora，孢子浓度较高，在农村地区比在城市的位置。在所选的孢子类型中，春秋孢子（鬼伞属、双孢霉属、小球腔菌属和多孢霉属）与温度呈负相关，与相对湿度和降雨量呈正相关。春末夏初黑穗病菌和夏季孢子（链格孢属、枝孢属、附球菌属、灵芝属、梗霉属和黑粉菌属）与温度呈显著正相关，与相对湿度和降雨量呈显著负相关。锈病是夏季常见的孢子类型，与温度呈正相关。曲霉属/青霉属，没有表现出相关性的气象因素分析。这些知识对农业很有用，可以更有效和可靠地使用杀虫剂，对人类健康也很有用，可以改善呼吸道过敏性疾病的诊断和治疗。
Although fungal spores are an ever-present component of the atmosphere throughout the year, their concentration oscillates widely. This work aims to establish correlations between fungal spore concentrations in Porto and Amares and meteorological data. The seasonal distribution of fungal spores was studied continuously (2005-2007) using volumetric spore traps. To determine the effect of meteorological factors (temperature, relative humidity and rainfall) on spore concentration, the Spearman rank correlation test was used. In both locations, the most abundant fungal spores were Cladosporium, Agaricus, Agrocybe, Alternaria and Aspergillus/Penicillium, the highest concentrations being found during summer and autumn. In the present study, with the exception of Coprinus and Pleospora, spore concentrations were higher in the rural area than in the urban location. Among the selected spore types, spring-autumn spores (Coprinus, Didymella, Leptosphaeria and Pleospora) exhibited negative correlations with temperature and positive correlations both with relative humidity and rainfall level. On the contrary, late spring-early summer (Smuts) and summer spores (Alternaria, Cladosporium, Epicoccum, Ganoderma, Stemphylium and Ustilago) exhibited positive correlations with temperature and negative correlations both with relative humidity and rainfall level. Rust, a frequent spore type during summer, had a positive correlation with temperature. Aspergillus/Penicillium, showed no correlation with the meteorological factors analysed. This knowledge can be useful for agriculture, allowing more efficient and reliable application of pesticides, and for human health, by improving the diagnosis and treatment of respiratory allergic disease.
