Olive flowering phenology variation between different cultivars in Spain and Italy: modeling analysis.

摘要: Phenology data are sensitive to identify how plants adapted local climate and they respond climatic changes. Modeling flowering phenology allows us the meteorological variables determining reproductive cycle. of temperate woody is assumed be locally climate. Nevertheless, recent research shows that adaptation may not an important constraint in predicting phenological responses. We analyzed variations dates Olea europaea L. at different sites Spain Italy, testing for a genetic differentiation among olive varieties estimate whether modeling necessary or not. build models onset peak Andalusia Puglia. Process-based using temperature as input variable photoperiod threshold date start accumulation were developed predict both dates. Our results confirm update previous indicated advance The indicate internal external validity higher used indicator cumulate temperature. use unified model localities provides standardized comparative study. regional grouping by similarities would factor responses face global increase.
