Projection des individus (Plot; en bleu) et des variables thermiques (en jaune) sur le plan principal de l’ACP (CP1 et CP 2) pour 2012, 2013 et 2014 avec TN = Température minimale; TX = Température maximale; IF = Indice de Fraîcheur de Nuits; IH = Indice de Huglin; GDD = Indice de Degrés Jours; Ath= Amplitude thermique du 1er janvier au 15 mars; NDT35 et NHT35 = Nombre de Jours et nombre d’Heures avec une Température au dessus 35°C. Les carrés pointillés indiquent les variables très fortement corrélées (r2 > 0,83). Projections of plots (in blue) and temperature variables (in yellow) in the principal plan (PC1 and PC2) for 2012, 2013 and 2014, with TN = Minimal Temperature; TX = Maximum Temperature; IF = Cool Night Index; IH = Huglin Index; GDD = Growing Degree Days; Ath= Thermal Amplitude between the 1st of January and the 15th of March; NDT35 et NHT35 = Number of Days and number of Hours with temperature over 35°C. Dotted squares indicate variables with high correlation (r2 > 0.83).
