“…Leite et al (2019) confirmed the outcomes of several studies on the negative effects of drought on cork growth (Caritat et al, 1996;Costa et al, 2016;Oliveira et al, 2016), reinforcing that spring and winter rain strongly influence phellogen activity. Ghalem et al (2018) found precipitation-temperature index thresholds below which cork growth should be constrained in drier climatic conditions. The climate/growth relationships are remarkably strong in young trees (< 30 years) of Q. suber (Leal et al, 2008).…”

“…Unlike the wood rings, which are often faint and indistinct (Natividade, 1950;Sousa et al, 2009), cork rings have clear boundaries and climate seems to be the dominant signal. Ghalem et al (2018) suggested that cork growth encodes a climatic signal and drought-driven cork growth reduction is a threshold function of the precipitation-temperature ratio, and with an expected increase in drought occurrence under changing climate conditions, cork growth is likely to be similarly affected in Mediterranean regions. Lack of precipitation effectively reduces soil water availability and lowers groundwater levels and, thus, directly constrains the corkring widths that are formed in each growing season, with important implications for cork yield (Mendes et al, 2016).…”

“…Les expositions favorables aux pluies (sud-ouest) des sites peuvent améliorer la croissance du liège par rapport aux expositions plus sèches. Ces expositions ont une bonne disponibilité en eau (Nadezhdina et al, 2008 ;Ghalem et al, 2018). La densité du peuplement reste en revanche sans aucun effet sur la formation du liège, ce qui est conforme avec les travaux de Torres et al (1997) et Sánchez-González et al (2007).…”

“…Le premier assure la reconstitution de la suberaie par des soins culturaux et des aménagements. Le second vise à produire, en quantité et de manière soutenable, un liège de bonne qualité selon trois paramètres essentiels : l'épaisseur, la porosité et les défauts du liège (Ferreira et al, 2000 ;Pereira, 2007 ;Ghalem et al, 2018). La combinaison de ces paramètres dégage sept classes commerciales de qualité de liège, allant de la bonne qualité, destinée à la fabrication de bouchons naturels d'une seule pièce, au liège de rebut, orienté vers l'industrie de trituration (Pereira et al, 1996 ;Sánchez-González et al, 2005).…”
