Le\u00a0Phytophtora cinnamomi<\/i>\u00a0est le pathog\u00e8ne responsable de la maladie tr\u00e8s r\u00e9pandue de l’encre du ch\u00e2taignier qui provoque des d\u00e9p\u00e9rissements importants au sein des peuplements. Une \u00e9tude s’est pench\u00e9e sur le sujet afin de d\u00e9terminer si les arbres parents transmettent des facteurs de r\u00e9sistance ou de tol\u00e9rance \u00e0 l’encre du ch\u00e2taignier et \u00e0 la s\u00e9cheresse. Des plants ont \u00e9t\u00e9 cultiv\u00e9s \u00e0 partir de groupes de parents sains et d’autres atteints par la maladie. Le fl\u00e9trissement foliaire apr\u00e8s une exposition \u00e0 la s\u00e9cheresse et la mortalit\u00e9 des semis apr\u00e8s inoculation de l’encre ont \u00e9t\u00e9 \u00e9valu\u00e9s.<\/p>\n

Les plants issus des arbres m\u00e8re infect\u00e9s montrent une croissance moins importante en hauteur et une biomasse racinaire plus faible que les plants dont les parents sont sains.<\/p>\n

Le fl\u00e9trissement des feuilles li\u00e9 \u00e0 la s\u00e9cheresse est similaire chez les deux populations, quelle que soit l’origine des plants. Cependant, une plus grande tol\u00e9rance \u00e0 la maladie a \u00e9t\u00e9 observ\u00e9e chez les plus petits semis, ce qui sugg\u00e8re que la tol\u00e9rance \u00e0 l’encre implique un co\u00fbt qui, dans ce cas, se manifeste sur la croissance.<\/p>\n

Ces r\u00e9sultats montrent qu’un pathog\u00e8ne peut influencer les performances et provoquer une r\u00e9ponse de la part d’une essence au sein de la g\u00e9n\u00e9ration suivante, ce qui cr\u00e9e une nouvelle pression de s\u00e9lection parmi la descendance.<\/p>","protected":false},"excerpt":{"rendered":"
