Observar a distribuição de água dentro do xilema fornece informações significativas sobre a dinâmica do fluxo de água em plantas lenhosas. Neste estudo, demonstramos a abordagem prática para observar a distribuição de água de xilema in situ usando um criostat e Cryo-SEM, que elimina mudanças artifactuais no estado da água durante a preparação da amostra.
