The relative susceptibility to fusiform rust of provenances of 6 European species of pine was tested at Athens, Georgia U.S.A. Needle and stem spots caused by rust were found on the seedlings of all the species and their provenances. Several maritime pine and Aleppo pine seedlings showed particular longitudinal cracks caused by the fungus mycelium in the stem; those of Austrian pine and of Swiss Mountain pine had a violet zone around the cotyledons due to the presence of the fungus mycelium in the needle tissues. If the percentage of galled seedlings is taken into consideration, the test results indicate that Aleppo pine, Austrian pine and Italian stone pine are more susceptible to infection than are maritime pine, Swiss Mountain pine or Scots pine.
