Microclimatic-induced fluctuations in the flower and pollen production rate of olive trees (Olea europaea L.)

摘要: Abstract The possible impact of altitude and the related microclimatic conditions on total production fruiting branches, inflorescences, flowers pollen grains olive trees Olea europaea was analysed. A 90 Picual cultivar trees, most extensive in Iberian Peninsula, were studied for a three-year period (2007–2009). study shows that tree varies according to microclimate. Our also indicates frequently can have up half million per tree. Moreover, flower differs between years areas. In cultivar, average anther is usually more than 60 000 grains. around 72 000 average. favourable reproduction are found growing areas with low temperature high precipita...
