Cupressaceae pollen is one of the major airborne allergens of the Mediterranean region and in other regions around the world. Pollen production of these species causes considerable allergic problems during winter, being this type of pollen the most abundant in this period of the year. This work aims to relate phenology, meteorology and airborne pollen records in these species. Aerobiological sampling was carried out in Badajoz (SW Spain) from 2016 to 2018 using Hirst-type volumetric sampler. Pollination phenology was studied in 50 specimens, ten of Cupressus macrocarpa , ten of Cupressus arizonica , 15 of Cupressus sempervirens and 15 of Platycladus orientalis with a frequency of 3–4 days on average during the months of January to March. In all cases, five specimens were in the surrounding of pollen station and at least five of them 4 km apart. For phenology, BBCH methodology was used. Daily data for the whole period and hourly data for the last 2 years were analyzed, including pollen records and meteorology. Comparison between pollen records and sources distribution was assessed. Main pollen season lasted on average 91 (89–94) days. In all the years, the peaks of phenology of the different species can be matched with peaks of airborne pollen records, considering that rain can prevent a more precise correspondence.

柏科城市基础设施物候与其花粉含量和气象变量相关

柏科花粉是地中海地区和世界其他地区的主要空气过敏原之一。这些物种的花粉产生在冬季引起相当大的过敏问题,这种花粉在一年中的这个时期最为丰富。这项工作旨在将这些物种的物候学、气象学和空气中的花粉记录联系起来。2016 年至 2018 年在巴达霍斯(西班牙西南部)使用 Hirst 型体积采样器进行了空气生物采样。对50个标本进行了授粉物候研究,其中大果柏10个,亚利桑那柏10个,柏木15个,侧柏15个,1-3月平均为3-4天。在所有情况下,花粉站周围有五个标本,其中至少有五个相距 4 公里。对于物候学,使用 BBCH 方法。分析了整个时期的每日数据和过去 2 年的每小时数据,包括花粉记录和气象。评估了花粉记录和来源分布之间的比较。主要花粉季节平均持续 91 (89-94) 天。多年来,考虑到雨水可以阻止更精确的对应,不同物种的物候峰可以与空气中花粉记录的峰匹配。
