2008-2011年，对榛属7个类群的雄花序开花进行了物候学观察。americana、美洲角蝉C . avellana，C . avellana 'Contorta'、圆叶拟步行虫C. avellana 'Pendula'、尖吻隐翅虫C.× colurnoide s，C . cornuta、C.极大，生长在卢布林的玛丽亚·居里-斯克洛多夫斯卡大学植物园。同时，榛子花粉在卢布林的大气中的季节进行了分析，使用达勒姆采样器。这项工作的目的是评估开花在7 Corylu的类群与选定的气象要素，并描述在2008年至2011年的花粉季节。在研究的几年里，在所研究的榛类群的年度物候周期显着不同的连续开花阶段的发病时间。在四年的观测中，榛花开花的最早开始是在1月底，而最晚的是在3月底。最早的盛开发生在2月的第一个十年，最晚的是在4月的第一个十年。开花的结束是在2月或4月的第一或第二个十年。每年，C。avellana是第一个开花的，随后C. americana、美洲角蝉C.× colurnoides，C. maxima、大斑隐翅虫C. avellana 'Pendula'、尖吻隐翅虫C. avellana 'Contorta'和C.角状的研究期间的花粉季节开始于1月底，2月的第二个十年或3月的第一个十年。花粉季节的结束最经常发生在4月的第一个或第二个十年。花粉季节的长度从38到49天不等，而单个类群的花期平均为22天。在四个研究年度中，C. avellana和花粉季节的开始正好在同一天，而其他分类群的开花开始通常是在花粉季节开始后报道的。C . avellana 'Contorta'和C.花粉季后5 ~ 16 d为角质形成期。花序发育与最高温度和空气相对湿度的关系最为密切。
In the years 2008-2011, phenological observations of flowering of male inflorescences were carried out in seven taxa from the genus Corylus : C . americana , C . avellana , C . avellana ‘Contorta’, C. avellana ‘Pendula’, C. × colurnoide s , C . cornuta , C. maxima , grown in the Maria Curie-Sklodowska University Botanical Garden in Lublin. Simultaneously, the hazel pollen seasons in the atmosphere of Lublin were analysed using a Durham sampler. The aim of the work was to assess the flowering in seven Corylu s taxa in relation to selected meteorological elements and to describe the pollen seasons in the years 2008-2011. During the study years, the annual phenological cycles in the studied Corylus taxa differed markedly in terms of timing of the onset of the successive flowering phases. During the four years of observations, the earliest beginning of hazel flowering was found at the end of January, whereas the latest – at the end of March. The earliest full bloom took place in the first decade of February, and the latest – in the first decade of April. The end of flowering was reported in February or in the first or second decade of April. Each year, C. avellana was the first to produce flowers and it was subsequently followed by C. americana , C. × colurnoides , C. maxima , C. avellana ‘Pendula’, C. avellana ‘Contorta’, and C. cornuta . The pollen seasons in the study period began at the end of January, in the second decade of February, or in the first decade of March. The end of the pollen seasons most frequently took place in the first or second decade of April. The length of the pollen seasons ranged from 38 to 49 days, while the length of the flowering periods in the individual taxa was 22 days on average. During the four study years, the onset of flowering in C. avellana and the beginning of the pollen season coincided on the same day, whereas the onset of flowering in the other taxa was usually reported after the beginning of the pollen seasons. The flowering period of C . avellana ‘Contorta’ and C. cornuta lasted from 5 to 16 days after the pollen season. The development of inflorescences was most closely related to maximum temperature and relative air humidity.
