The cytology of one strain of tumor tissue from the spruce tree, Picea glauca, grown in vitro for more than a year was examined. The cells of this strain are characterized by a uniform chromosome number of 24, and the strain appears to be quite stable. The implications of the results of this study and previous studies on similar material are discussed.
