“…Especially in northern Europe, Betula is a very important allergy plant with 10-15% of the population sensitised to its allergens. It is also a significant cause of allergy in central Europe and North and Central Asia (D'Amato et al, 1991;Savitsky & Kobzar, 1996;WHO, 2003). In North America, Betula, Alnus and Corylus are regarded as allergy plants over wide geographic areas.…”

Many anemophilous, early-flowering tree genera include allergy plants of world-wide significance. We studied the synchronisation of high and low pollen years in the genera Betula, Alnus, Corylus, Salix and Populus and the cumulative effects that an increasing number of taxa has on the number of days of exposure to different levels of allergenic pollen in North Europe. The proximal causes of the inter-annual variations of airborne pollen loads were analysed with a multiple regression analysis. The annual fluctuations of airborne pollen sums were compared between genera and found to be positively correlated among all combinations of genera at the three study sites. Most correlations were statistically significant (pv0.05). The comparison between Betula and Alnus is discussed first. Betula pollen was clearly the most abundant airborne pollen type. The presence of Alnus pollen, however, significantly increased the predisposal to allergenic pollen. At all sites, the number of days per year when the Betula and Alnus pollen counts together exceeded 10 and 100 grains m 23 of air, was found to be greater than the number of days when the Betula pollen counts alone exceeded 10 and 100 m 23 of air. The difference was statistically significant. In Kuopio, the difference was found to be statistically significant even for grains per 1 000 m 23 of air of Betula and Alnus together compared with the same count of Betula pollen alone. Betula, Alnus and Corylus belong to the order Fagales and have cross-reacting main allergens. The flowering of Alder and Corylus culminate at the same time, two to four weeks earlier than that of Betula. Due to synchronization of high and low years and the mostly non-overlapping flowering seasons, the time of exposure to pollen may be very long during the high years. Furthermore, Alnus and Corylus pollen may prime allergic people before the onset of the Betula season.

“…In North America, Betula, Alnus and Corylus are regarded as allergy plants over wide geographic areas. Salix and Populus, the broad-leaved genera belonging to the Salicaceae (willow family, order Malphigiales), have a circumpolar distribution and are also significant allergy plants (D'Amato et al, 1991;Hough, 1947;More & White, 2003;Savitsky & Kobzar, 1996).…”

“…Similar studies have been carried out in Russia and some other countries, revealing the pollination periods of the pollen and ensuring that the people of the sensitive region act cautiously (Savitsky and Kobzar, 1996). It has been shown that it helps in the diagnosis and treatment of seasonal rhinoconjunctivitis and pollen-induced asthma (Bass and Morgan, 1997).…”

In this study, comparative palynological characteristics and allergic features of the Yunus Emre campuses, Eskişehir/Turkey were investigated. Detailed palynomorphological investigation of the pollen grains of Salix taxa were carried out under Light Microscope and Scanning Electron Microscope (SEM). It was revealed that the pollen grains of investigated taxa were the tricolpat was seen to be tectatae-reticulatae ornamentation. Comparisons which will be made with the collected species and other taxa within the family will make contrib
