Abstract: | The possibility of creating a forecast model for grapeproduction using airborne pollen concentrations ofVitis vinifera L. was investigated. The studyarea is located in the province of Trento (46°11,11°08), North Italy. Because of its prestigious wineproduction, the area is quite important on a nationalscale.Airborne pollen concentration data (P/m3) werecollected for a five year period (1993–1997) with aHirst type sampler (VPPS 2000 – Lanzoni) following thestandard methodology proposed by the ItalianAeroallergen Network. For the same five-year period,grape production data (kg/ha) from vineyards adjacentto the pollen sampler were used along with provincialdata. Regression lines were constructed using the Lnof the annual sum of daily pollen concentrations (Ip)as the independent variable and grape productionvalues as the dependent variable. Correlations betweenpollen data (pollen index, beginning and duration ofmain pollen season) and meteorological data(temperature and rainfall) are shown. |
