Mes recherches visent à identifier, chez des céréales tropicales (riz, mil, sorgho), des traits racinaires utiles au développement d’une agriculture plus durable et plus résiliente face aux climats futurs. Je m’interesse particulièrement à l’hydraulique racinaire et à son influence sur l’utilisation de l’eau par la plante dans différents contextes de stress hydrique.

Mots clés :

Système racinaire
Hydraulique
Stress abiotique
Céréales
