The present study aimed to characterize the mesoclimate of the municipality of Água Doce, Brazil, and its influence on the phenological development and thermal requirements of autochthonous Italian varieties (Vitis vinifera L). The climate data were provided by a local automatic weather station. The principal phenological stages of red varieties (Aglianico, Ancellotta, Lambrusco, Malvasia Nera, Negroamaro, Nero d’Avola, Primitivo, Sangiovese, and Rebo) and white varieties (Fiano, Garganega and Vermentino) are analyzed. Results show that the mean temperature measured during the phenological cycles from September to April were higher than the climatological average (1961 to 2012). According to the Winkler, Huglin, and Cool Night bioclimatic indexes, the region is classified as “Region II”, cold and with cool nights, respectively. The average heat summation for the phenological cycles of the varieties was 1740 GDD (205 days, 2009-2010), 1463 GDD (187 days, 2010-2011), and 1408 GDD (176 days, 2011-2012). The Lambrusco variety presented the longest phenological cycle (203 days), while Garganega presented the shortest one (178 days). The lower temperatures of Água Doce, when compared to those in other regions where the varieties are traditionally produced, determine longer growing cycles and a shift in the timing of the phenological stages
Il presente studio ha lo scopo di caratterizzare la mesoclima del Comune di Água Doce, Brasile, e la sua influenza sullo sviluppo fenologico e requisiti termici di varietà autoctone italiane (Vitis vinifera L). I dati climatici sono stati forniti da una stazione meteorologica automatica locale. Le principali fasi fenologiche di varietà rosse (Aglianico, Ancellotta, Lambrusco, Malvasia Nera, Negroamaro, Nero d'Avola, Primitivo, Sangiovese, e Rebo) e varietà a bacca bianca (Fiano, Garganega e Vermentino) vengono analizzati. I risultati mostrano che la temperatura media misurata durante i cicli fenologici da settembre ad aprile erano più alti rispetto alla media climatologica (1961-2012). Secondo il Winkler, Huglin, e fresco indici bioclimatici Notte, la regione è classificato come "Regione II", freddo e con notti fresche, rispettivamente. La sommatoria di calore medio per i cicli fenologici delle varietà erano 1740 GDD (205 giorni, 2009-2010), 1463 GDD (187 giorni, 2010-2011), e 1408 GDD (176 giorni, 2011-2012). La varietà Lambrusco ha presentato il più lungo ciclo fenologico (203 giorni), mentre Garganega ha presentato il più breve (178 giorni). Le temperature più basse di Água Doce, rispetto a quelli di altre regioni in cui le varietà sono prodotti tradizionalmente, determinano più lunghi cicli di crescita e un cambiamento nel calendario delle fasi fenologiche

Abstract
The present study aimed to characterize the mesoclimate of the municipality of Água Doce, Brazil, and its influence on the phenological development and thermal requirements of autochthonous Italian varieties (Vitis vinifera L). The climate data were provided by a local automatic weather station. The principal phenological stages of red varieties (Aglianico, Ancellotta, Lambrusco, Malvasia Nera, Negroamaro, Nero d’Avola, Primitivo, Sangiovese, and Rebo) and white varieties (Fiano, Garganega and Vermentino) are analyzed. Results show that the mean temperature measured during the phenological cycles from September to April were higher than the climatological average (1961 to 2012). According to the Winkler, Huglin, and Cool Night bioclimatic indexes, the region is classified as “Region II”, cold and with cool nights, respectively. The average heat summation for the phenological cycles of the varieties was 1740 GDD (205 days, 2009-2010), 1463 GDD (187 days, 2010-2011), and 1408 GDD (176 days, 2011-2012). The Lambrusco variety presented the longest phenological cycle (203 days), while Garganega presented the shortest one (178 days). The lower temperatures of Água Doce, when compared to those in other regions where the varieties are traditionally produced, determine longer growing cycles and a shift in the timing of the phenological stagesFile | Dimensione | Formato | |
