The pollination period and pollen concentrationof olive trees (Oleaeuropea L.) and olive production were analysedfor Prato and Florenceusing a data set of 8 years (1991–1998).Meteorological data have been usedto obtain information about weather conditionsduring vegetative seasonsand correlations were found both for thephenology and yield.

The results showed that air temperatureprevious to the onset of floweringis of great importance in determining thereproductive cycle of olive treebut the chill period in January and Februaryshould also be considered.Olive pollen collected during thepollination period was positivelycorrelated with the production level for bothsites. Weather conditionfollowing pollination were also taken intoaccount for a better assessmentof the final yield.
