Summary
Air-borne pollen grains were collected using Hirst volumetric spore traps in both Ascoli Piceno and Perugia during the March–November 1983 period. Similar types of pollens were recorded in both towns. In Perugia, higher total amounts of Cupressaceae/Taxaceae pollens were recorded in March and of Quercus, Gramineae, Urticaceae and Oleaceae in May–June. However, the pollen concentration in the Ascoli Piceno atmosphere was higher in the August–October period owing to the pollen of the «summer weeds».
Riassunto
I granuli di polline aerodiffusi sono stati campionati con trappole volumetriche tipo Hirst sia in Ascoli Piceno che in Perugia durante il periodo marzo–novembre 1983. In entrambe le città sono stati rilevati tipi di polline simili. In Perugia sono state registrate concentrazioni di polline in atmosfera più elevate rispetto ad Ascoli Piceno in marzo per la pollinazione di Cupressaceae/Taxaceae e in maggio–giugno per la pollinazione di Quercus, Gramineae, Urticaceae e Oleaceae. In Ascoli Piceno, invece, la concentrazione di polline in atmosfera è state più elevata di Perugia nel periodo agosto–ottobre per la pollinazione delle «erbe estive».
