Nodulation and growth of young seedlings were investigated, in near-threatened trees, Alnus trabeculosa and soil saving trees, A. hirsuta var. sibirica. Nodulose young seedlings of A. trabeculosa were observed after application of root nodules and/or root chips from mature trees on the roots of young seedlings, especially, nodulose seedlings were increased applied with root nodules and root chips. Root length of these young seedlings were shorter than non-nodulose seedlings, but the number of leaves and chlorometer readings were higher than that of non-nodulose seedings. Nodules were recognized in young seedlings of A. hirsuta var. sibirica applied with suspension of crushed nodules of A. trabeculosa. Moreover, the number of leaves, length of leaf and chlorometer readings were improved on seedlings treated with a water solution of potassium phosphate and crushed nodules. Fungus that forms nodules on the roots of A. trabeculosa have the properties of Frankiae spp., because this fungus could form nodules on the roots of A. hirsuta var. sibirica.
