| Abstract: | At Florence, Italy, several species of pine were experimentally infected with blister rust. Inoculations were carried out on 3 and 15 months-old seedlings. After antificial and natural inoculation, Brutia, Aleppo, Austrian, Swiss mountain, Maritime and Italian stone pine showed pyenia and aecia. Spotted seedlings of Ponderosa pine showed only mycelium of C. flaccidum in needle and stem tissues. The exotic species seemed to have a very high degree of resistance to blister rust. |
