Ultrastructural abnormalities in phloem albuminous cells of needles of young pine seedlings from two Finnish nurseries suffering from the growth disturbances of conifer seedlings were studied. Needle samples were taken from growth disturbed seedlings and from healthy looking nursery seedlings as well as from naturally born forest seedlings. The results are discussed in relation to the possibility of virus disease in growth disturbed seedlings. The first trials to observe the viruslike particles from abnormal seedlings will be discussed, too.
