Analisi degli impatti della variabilità climatica sul Sangiovese

The increase of greenhouse gases in the atmosphere is causing a rise of terrestrial mean temperature, which can lead to wide changes in atmospheric events and in the distribution of vegetation. Temperature increases will lead to several consequences: longer growing season but, as the same time, faster physiologic plant growth, and therefore smaller final production; greater risk of pathogenic attacks and greater request for irrigation water. About grapevine, the more delicate growth phases, sch as the very early ones, will be even more vulnerable with climate changes. In particular, late frost risks will increase. A quality problem could arise, because faster plant growth will lead to lower grape quality. Besides, high maximum temperatures during summer months may cause an excessive fruit ripening, against fruit quality. On these bases, this study covers some aspects of the analysis of the impacts of climatic variability on Sangiovese responses, based on historical climate data in the main cultivation areas.
