Study of the incidence of meteorological parameters on the flowering of Quercus by means of its pollen production

Silva I., Muñoz A.F., Tormo R., Olea L.

The period of pollination of Quercus in Extremadura was analyzed over four years, monitoring atmospheric pollen levels. There were clear interannual differences in both recorded concentrations and phenology. Significant correlations were found with temperatures between January and May, rainfall from February to April, and the date of the last frost, which would explain the aforementioned differences.
