L'observation de la distribution d'eau dans le xylisme fournit des informations significatives sur la dynamique du débit d'eau dans les plantes ligneuses. Dans cette étude, nous démontrons l'approche pratique pour observer la distribution d'eau de xylée in situ en utilisant un cryostat et cryo-SEM, qui élimine les changements artifactual dans l'état de l'eau pendant la préparation de l'échantillon.
