Abstract
Long-term prediction models for climate change provide a new pattern of spread for the olive growing toward the North and the more internal area in Italy ( Tanasijevic et al., 2014). Climate change represents for Italian olive growing a chance to obtain more intensive and rational orchards. New genotypes or current known cultivars could be used but a new ideotype needs to be defined to respond to the peculiar environmental conditions. The main trait to be selected is the frost tolerance. A wide experimental work is in progress, involving private farmers and public institutions aiming to select cold tolerant varieties under different environmental conditions. Three experimental olive orchards were planted in Piemonte, Friuli Venezia Giulia and Lombardia regions by private farmers with common olive varieties. In the past, mostly empirical observations were conducted around the agronomic behavior of the olive cultivars related this trait. This year, a cold perturbation ('Burian'), started in late winter (February, 28) , severely damaged most of the olive orchards located in the Central and Northern Italy. In an effort to evaluate the agronomic behavior of the olive germplasm in response to late cold, preliminary data were collected and here discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
