Curly birch (Betula pendula var. carelica (Merklin) Hejtmanek) is widely distributed over north-western part or Russia, including the Baltic Soviet Republics and Belorussia. Experiences of growing this decorative species in Soviet Karelia and Leningrad region are presented. Commonly used classifications of the species are described, and recommendations for management of curly birch cultures and production of planting stock in greenhouses are given.

The forestry working group of the committee for scientific and technical cooperation between Finland and the Soviet Union initiated cooperation work between the two countries in the field of forestry almost ten years ago. The Finnish organizations the Department of Peatland Forestry, the Finnish Forestry Research Institute, and the Institute of Peatland Forestry of the University of Helsinki participated in the activity. From the Soviet Union the participants have been the Ministry of Forestry, the Russian Federation of USSR, and the Forestry Research Institutes of Leningrad and Estonia.
This paper includes the papers presented in the joint symposium arranged at the Forest Field Station of University of Helsinki on 17.9.1979. The 9 Russian lectures and the 8 Finnish ones, are presented either in their entirety or slightly condensed variably in Finnish, English or Russian. The summary of the seminar is presented in English and in Russian.
As a part of the scientific and technical cooperation between Finland and the USSR a symposium and an excursion on forest genetics and seed production was organized in Finland in August 1978. The symposium paper presented at Punkaharju are published here in order to bring them available for a wider audience.
The 12 symposium reports deal with the following subjects: Practical application of forest genetic research (A.I. Novoselceva), geographical variability and provenance transfer (E.P. Prokazin, M. Hagman, I. Etverk), variation in wood density (P. Velling), variation of flowering and seed crops in seed orchards (Y.P. Efimov), and natural stands (V. Koski), vegetative propagation (J. Niiranen), seed size effects and early test problems (J. Mikola), quantitative analysis of genotypic and environmental effects (S.A. Petrov), hormonal induction of flowering (O. Luukkanen) and x-ray photography analysis of the ageing of seeds during storage (M. Ryynänen).

The main forest research institutes in USSR as well as schools for higher education in forestry are presented in this article, on the basis of observations made during study tours and the relevant literature. Research in forest genetics, tree physiology and related fields i stressed. The State Forestry Committee leads the regional units of forestry administration and also governs a number of research institutes. Among these, the All-Union Forest Research Institute near Moscow has a central position. Regional institutes as well as those specializing in a particular field within forest research may belong to this category, too. Basic research, on the other hand, is conducted under the auspices of the Academy of Sciences, the Academy of Agricultural Sciences or academies of sciences of the Soviet republics. This type of institute also includes those devoted purely to forestry. Forest education at the university level takes place in schools usually called institutes of forest technology.

Forest research in the U.S.S.R. aims for increased productivity, improvements in timber quality and forest protection, and for better understanding of the environmental impacts of forests. Research institutes are organized under the U.S.S.R. Academy of Sciences, the State Committee of Forestry, the Forestry Committees of the Soviet Republics, or under some other institutions. Direct government subsidies as well as economic support from production enterprises are available as funding for these institutes. International cooperation in forest research, especially among the S.E.V. countries is strongly emphasized. As regards other countries, the well-established program for mutual exchange for forestry information and forest researchers with Finland should be mentioned.

From the tree breeder’s point of view, an investigation of the chemical compounds in a tree population is worthwhile, if sufficiently high correlations exist between the chemical composition and any economical important characteristics. In Scots pine (Pinus sylvestris L.) populations, such a correlation seems to exist between a high α-pinene and a low Δ3-carene content on the one hand, and the poor resistance to Fomitopsis annosa Fr. (now Heterobasidion annosum (Fr.) Bref.) but a rapid development during the first half of the life cycle on the other hand. Detailed investigation on the terpene contents in pine populations were conducted at 121 locations throughout the Soviet Union. As a result, the range of this species was divided into zones, each of which was characterized by a distinct terpene composition pattern. In continuing selection and breeding work, the terpene contents are being used as indicators when the variation of economically important characteristics of Scots pine populations is studied.
