Plus que la chaleur, c\u2019est le manque d\u2019eau qui est en cause.
\nVoil\u00e0 plusieurs ann\u00e9es, en for\u00eat de Champenoux (France), plusieurs arbres ont \u00e9t\u00e9 \u00e9quip\u00e9s de capteurs par l\u2019INRA, afin d\u2019\u00e9tudier leur croissance et les mouvements de r\u00e9traction des troncs. Le constat ? Le manque d\u2019eau pousse les arbres \u00e0 fermer leurs stomates pour \u00e9viter la transpiration et arr\u00eater leur croissance. Certains arbres ont ainsi arr\u00eat\u00e9 leur d\u00e9veloppement d\u00e9but juillet, allant m\u00eame jusqu\u2019\u00e0 maigrir dans le cas d\u2019une s\u00e9cheresse prolong\u00e9e. L\u2019interruption du processus de transpiration a eu pour cons\u00e9quence un r\u00e9chauffement des feuilles, d\u00e9gradant les pigments foliaires et engendrant un changement de couleur ou un ass\u00e8chement des feuilles.
\nLe changement climatique engendrera des \u00e9pisodes de s\u00e9cheresse plus intenses et plus fr\u00e9quents \u00e0 l\u2019avenir : il s\u2019agit donc d\u2019adapter la sylviculture pour diminuer la comp\u00e9tition li\u00e9e \u00e0 l\u2019eau et diversifier les essences en for\u00eat pour mieux exploiter les diff\u00e9rentes couches du sol.
