[ES] Presentamos los resultados obtenidos durante cuatro años de estudio (1994-1997) del contenido atmosférico de polen de Olea europaea L. en Madrid (Ciudad Universitaria) y en Aranjuez. A partir de las concentraciones medias diarias, hemos calculado el Período de Polinización Principal (PPP) para cada año y cada estación, que se ha producido siempre entre las semanas 16 y 26, con valores máximos diarios registrados entre el 3 de mayo y el 7 de junio. La presencia del polen de olivo ha sido mayor en Aranjuez que en Madrid (media del período, 3.307 granos de polen/año y 2.123, respectivamente). Las estación polínica transcurre de forma similar en ambas localidades. De una primera comparación de los datos polínicos con los datos de temperatura y precipitación, parece deducirse que las temperaturas acumuladas durante el período preestacional pueden tener una influencia decisiva en el inicio de la polinización, no así las precipitaciones. Tampoco parece clara su influencia sobre el total anual de polen recogido.
[EN] The results of four years of study (1994-1997) of the atmospheric levéis of pollen from Olea europaea L. in Madrid and Aranjuez are presented. The principal pollination period (PPP) for each year and each season were calculated, using the mean daily concentrations, and fell between weeks 16 and 26, with maximum daily valúes registered between 3rd May and 7th June. The presence of olive pollen was greater in Aranjuez than in Madrid (mean 3,307 grains of pollen/year and 2,123 grains/year, respectively). The pollen season was similar in each locality. A preliminary comparison of pollen data with temperature and precipitation seems to indicates that accumulated pre-season temperatures, but not rainfall, can have decisive influence on the initiation of pollination. His nuclear what influence rainfall has on the account of pollen collected.
