摘要: Airborne pollen concentration patterns reflect flowering phenology of a given species, and it may be sensitive regional indicator in climate change studies. This paper presents the relationship between strategic biological event, such as olive flowering, air temperature trend, registered over large scale (1982–2007) Umbria region. The aim study was to determine relationships phenological behaviour (flowering) trees trend data on phase were indirectly through an aerobiological monitoring technique. obtained results showed strong thermal trend. characteristic confirmed from correlations (mean 1st March) dates, especially that full (r = −0.9297). Moreover, advance 6, 8 10 days, respectively start, end dates. recorded time this period is ascribe mainly increase mean above all months May June.
