Shoot apical meristems of hop plants infected with hop stunt viroid (HSV) were examined for cytopathic changes. No measurable changes in ultrastructure were found in shoot tip 0.2 mm long bearing apical dome and two pairs of the primordia, whereas in the 3rd leaf primordium cell walls were undulate and/or frequently were irregular in thickness. These cell wall abnormalities were not observed in comparable shoot tips of the uninoculated hop plants or HSV‐free hop plants obtained by meristem tip culture.
