摘要

Relationships between weather parameters and airborne pollen loads of Pinus in Brisbane, Australia have been investigated over the five-year period, June 1994―May 1999. Pinus pollen accounts for 4.5% of the annual airborne pollen load in Brisbane where the Pinus season is confined to the winter months, July―early September. During the sampling period loads of 11 → 100 grains m~(-3) were recorded on 24 days and 1―10 grains m~(-3) on 204 days. The onset and peak dates were consistent across each season, whereas the end dates varied. The onset of the Pinus pollen season coincided with the coolest average monthly temperatures (< 22℃), lowest rainfall (< 7mm), and four weeks after daily minimum temperatures fell to 5―9℃ in late autumn. Correlations obtained between daily airborne Pinus pollen counts and temperature/rainfall parameters show that densities of airborne Pinus pollen are negatively correlated with maximum temperature (p < 0.0001), minimum temperature (p < 0.0001) and rainfall (p < 0.05) during the main pollination period. The mean duration of each pollen season was 52 days; longer seasons were shown to be directly related to lower average seasonal maximum temperatures (r~2 = 0.85, p = 0.025). These results signify that maximum and minimum temperatures are the major parameters that influence the onset and duration of the Pinus pollen season in the environs of Brisbane. Respiratory allergy is an important health issue in Brisbane, Australia, but it remains unknown whether or not airborne Pinus pollen is a contributing factor.
