Discussion

Hydrosis is most commonly associated with bacterial plant diseases.  Hydrosis occurs as plant cellulalar contents are released (by the processes of infection) into the intercelleular spaces.  Water-soaked plant tissue may be submitted to the test for bacterial streaming to confirm the presence of bacteria in the tissue.
