“…However, it is not clear how much "high" may be the percentage of Olea pollen in modern agrarian landscapes. Today, Olea pollen is common and among the most abundant airborne pollen in the Mediterranean countries (e.g., Galán et al, 2004;Ziello et al, 2012;Mercuri, 2015). In aerobiology, volumetric spore traps were placed in olive groves to study the phenology and the delayed pollination season of olive groves located at higher altitudes (in SE Spain: Aguilera and Valenzuela, 2012).…”

Modern pollen spectra are an invaluable reference tool for paleoenvironmental and cultural landscape reconstructions, but the importance of knowing the pollen rain released from orchards remains underexplored. In particular, the role of cultivated trees is in past and current agrarian landscapes has not been fully investigated. Here, we present a pollen analysis of 70 surface soil samples taken from 12 olive groves in Basilicata and Tuscany, two regions of Italy that exemplify this cultivation in the Mediterranean basin. This study was carried out to assess the representativeness of Olea pollen in modern cultivations. Although many variables can influence the amount of pollen observed in soils, it was clear that most of the pollen was deposited below the trees in the olive groves. A rapid decline in the olive pollen percentages (c. 85% on average) was found when comparing samples taken from IN vs. OUT of each grove. The mean percentages of Olea pollen obtained from the archeological sites close to the studied orchards suggest that olive groves were established far from the Roman farmhouses of Tuscany. Further south, in the core of the Mediterranean basin, the cultivation of Olea trees was likely situated ∼500-1,000 m from the rural sites in Basilicata, and dated from the Hellenistic to the Medieval period.

“…Furthermore, meteorological conditions could exercise an indirect effect on the various events involved in pollen release and dispersal, ovule development and pollen tube growth, mainly in crossed fecundation varieties (Ebadi et al, 1995). Some multi-year studies on olive and grape have demonstrated a close relationship between the quantity of pollen released during the flowering and fruit production (Fornaciari et al, 1998;Minero et al, 1998;Galán et al, 2004Galán et al, , 2008.…”

“…pistil abortion, fruit drop, fruit size). Hence, studies reporting positive correlations between abundance of flowering (or pollen in the air) and yield (Moriondo et al, 2001;Fornaciari et al, 2002, Galán et al, 2004, would imply not a causal relationship but simply correlated phenomena: bloom and yield both represent an expression of the tree yield potential. The redundant flowering in olive, may serve the purpose of increasing the mail and the overall fitness, which is advantageous from an evolutionary point of view, but wasteful from an agronomical perspective.…”
