[Cf. FA 35, 62] Describes some distinguishing characteristics, relative to the diploid, of 14-year-old tetraploid trees grown in Korea: tracheid diameters were more variable and the mean value was somewhat higher; the width and thickness of the central cylinder of the needles was significantly greater, and the needles had very few resin canals; and the cones were larger and heavier. Isoperoxidase patterns were not significantly different. The seeds were infertile. Figures and tables have English captions.
