Two-year-old lodgepole pine (Pinuscontorta Dougl. var. latifolia Engelm.) seedlings were each inoculated with one of 12 isolates of the Armillariamellea complex. All isolates were pathogenic but differed in the amounts of infection and mortality that they caused. An isolate of A. mellea s.str. and four Alberta isolates of North American biological species V (NABS V) caused the most mortality; however. A. mellea s.str. killed seedlings more quickly than NABS V. Seven Alberta isolates of NABS I infected and killed relatively few seedlings compared with NABS V and A. mellea s.str.

Armillaria Root Rot

Two experiments were conducted to test the hypothesis that white spruce (Piceaglauca (Moench) Voss) is less liable than lodgepole pine (Pinuscontorta Dougl. var. latifolia Engelm.) to be attacked by Alberta isolates of Armillaria. In the first experiment, 27 two-year-old containerized pine and spruce were inoculated with each of 19 different isolates representing North American biological species (NABS) I and V, the Foothills variant of NABS I, and A. mellea s.str. In the second experiment, 10 containerized seedlings of both species were inoculated with eight different isolates of NABS I and transferred to 2-L pots 2 months later. Inoculum survived better in association with spruce seedlings than with pine. In both experiments, spruce seedlings were more frequently infected than pine seedlings, and more likely to die when infected, although this difference was significant only in the first experiment. Favoring or planting spruce on sites with Armillaria root rot, therefore, cannot be recommended in Alberta.

First Time

Genetic hybridization and karyotypic analyses revealed the biological species Saccharomyces paradoxus and Saccharomyces cerevisiae in exudates from North American oaks for the first time. In addition, two strains collected from elm flux and from Drosophila by Phaff in 1961 and 1952 were reidentified as S. paradoxus. Each strain studied showed a unique profile of chromosomal hybridization with a probe for the retrotransposable element Ty1. The wild distribution of natural Saccharomyces sensu stricto yeasts is discussed.Key words: genetical taxonomy, Saccharomyces paradoxus, oak exudates, Ty elements, electrophoretic karyotyping.

Abundance And Distribution

The abundance and distribution of rhizomorphs of Armillaria spp. in the soil were quantified in undisturbed stands and in stands defoliated 1 and 5 years previously by insects. Although the species of Armillaria was not determined, similar mixed oak forests in south central Pennsylvania contain North American biological species VII (Armillariabulbosa Barla.). Several analysis techniques were tested for sensitivity to differences in distribution of rhizomorphs. Rhizomorph distribution within the 0.04-ha study plots was uniform in the undisturbed stands, but was significantly greater near dead trees in the defoliated stands. Total rhizomorph abundance was greater on plots defoliated 5 years before sampling than on more recently defoliated plots, and it was least on undefoliated plots. Rhizomorph density near dead trees was highly correlated with overall rhizomorph density. Greater rhizomorph abundance near recently dead trees or stumps may have important implications for management decisions in the presence of gypsy moth (Lymantriadispar L.) infestations.

The article presents the results of the introduction of the North American flora woody species of the pine family (Pinaceae Lindl.) to the European North of Russia. The research purpose is to select the most valuable specimens for introduction into northern conditions from the tree species collection. The research has involved experimental, calculation, analytical, and comparative methods. The conclusion on the result of the introduction of a particular plant was based on the materials of long-term phenological observations, which were carried out according to the method of botanical gardens improved for the conditions of the European North of Russia. As a result of the introduction of North American species of the Pinaceae Lindl. family to the region, a large-scale test of foreign conifers was carried out for the first time; a collection of 2 species of fir, 4 species and 3 forms of spruce, 2 species of pine, and 1 species of Douglas fir was created. Most attention was paid to the introduction of species of the genus Pinus. Positive results of cultivation of Pinus contorta Loud. var. latifolia S. Wats. in the Dendrological garden allowed us to select it for further introduction testing in experimental plantations of the region. On plantations located in the Arkhangelsk and Vologda regions and the Komi Republic, 104.2 ths seedlings were grown from the seed samples, mostly from the northern natural range of this pine. Unfortunately, not all of the breeding material for the North American pine species tested was derived from natural growth sites, which puts into question some of the unsatisfactory results. Therefore, for Jack pine and Weymouth pine, it is advisable to use in testing additional samples from the most northern regions of their natural ranges in Canada. Many of these species are of both scientific and practical interest for forestry. To assess the economic value of those introduced species, adaptive capabilities of which in the conditions of the European North according to the results of studies are not in doubt, it is advisable to lay out pilot plantations in the region, similar to the already created plantings of North American lodgepole pine (Pinus contorta Loud. var. latifolia S. Wats.). The concentration of different species like balsam fir (Abies balsamea Mill.), Fraser fir (Abies fraseri (Pursch.) Poir.), American larch (Larix laricina (Du Roi) K.Koch.), Canadian spruce (Picea glauca Voss.), Engelmann’s spruce (Picea engelmannii Engelm.), black spruce (Picea mariana Britt.), Jack pine (Pinus banksiana Lamb.), lodgepole pine (Pinus contorta Loud. var. latifolia S. Wats.), and Douglas fir (Pseudotsuga menziesii Mirb.), involving several seed origins from the most northern regions of its natural range for each, in 2-3 forest areas will allow creating a valuable introduction object; scientific and practical importance of those mentioned cannot be overestimated.
