| Abstract: | This paper presents a 2-year survey ofArtemisia airborne pollen concentrations in Murcia. An importantArtemisia blooming taking place in winter is confirmed in Murcia (SE Spain). This phenomenon could explain the incidence of winter
pollinosis in Murcia. On the other hand, for the first time, three consecutive pollen seasons ofArtemisia, corresponding to three different species (A. campestris, A. herba-alba andA. barrelieri) have been noted. Mathematical analyses show the relations between pollen concentrations ofArtemisia in summer and autumn, and precipitation occurring 6–8 weeks before. Blooming outsets seem to be related to cumulative percentage
of isolation from 1 March. Meteorological factors do not seem to influence pollen concentration in any significant way once
pollination has begun. |
