Distribution of Alien Fungi in Connection with the Introduction of Higher Plants

摘要

The methods of dissemination of fungi during the importation and acclimatization of alien plants was studied. A large group of coniferous species of economical and decorative importance which were brought from various countries of the world into the Crimea, especially to the Nikitskiy Botanical Garden were investigated. Altogether 83 species of plants were investigated of which 14 were native and 69 were species of alien origin. On these plants 200 species of fungi were found of which 154 species are described in the USSR for the first time. From the number of fungi of alien origin, a number of species were found which cause dangerous diseases, canker of the trunks, falling out in new sites of residence, imported plants in a whole number of cases may become affected by unknown fungi which they didn't have in their native land. The material in this work graphically shows that the introduction of plants is strongly connected with the parallel emanation together with it of the introduction of fungi and that the fungi are often capable of developing under conditions which are sharply different from the conditions in their native land. Wherever, the growth of plants is possible, fungi settle on them and this affects both the agricultural crop as well as decorative, forest, and other wild plants.
