Observation av vatten distributionen inom Xylem ger viktig information om vattenflödesdynamik i vedartade växter. I denna studie visar vi den praktiska metoden för att observera Xylem vatten distribution in situ genom att använda en kryostat och Cryo-SEM, vilket eliminerar artifaktuella förändringar i vatten status under prov beredning.
