Growth of Norway spruce (Picea abies (L) Karst.) provenances in Eastern North America
[Текст] / M. Holst ; Forest Research Branch, Canada. - Ottawa : Department of Forestry Publication, 1963. - 15 с. : табл. - (Department of Forestry Publication / Forest Research Branch ; 1022). - 0.10 р.
Библиогр.: p. 15
Аннотация: In the late 1930's, IUFRO (International Union of Forest Research Organizations) made available good seed of Norway spruce for establishment of provenance trials in eastern North America. Although World War II prevented best use of this material, several provenance experiments were planted. This paper: (1) reviews briefly the results to date of these experiments, (2) mentions several difficulties in growing Norway spruce, and (3) indicates the potential productivity of Norway spruce in various regions

Resistance to snow blight (Phacidium infestans Karst.) in different provenances of Pinus silvestris L.
[Text] = Resistens mot snoskytte hos olika tallprovenienser : научное издание / E. Bjorkman. - Stockholm : Skogshogskolan, 1963. - 16 p. : рис., табл., фото.цв. - (Studia Forestalia Suecica ; № 5). - eng. - Библиогр.: с. 14-15. - 0.05 р.
Аннотация: The experimental material was put out as 2+ 1 plants in the spring of 1954. In October 1956, four plants in each plot were inoculated with snow blight, and the remaing plants sprayed with a 3% solution of lime-sulphur to protect them from attack. The inoculated plants were all attacked by the fungus, and during the following winter constituted natural seats of infection; Details can be seen in table 1 and figs. 1 and 2

The phytotron in Stockholm
[Text] = Skogshogskolans fytotronanlaggning : научное издание / D. Wettstein. - Stockholm : Skoghogskolan, 1967. - 23 p. : рис. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 44). - eng. - Библиогр.: с. 8. - 1.04 р., 0.30 р.
Аннотация: These preliminary observations demonstrate that the phytotron will make it possible to determine the various photo- and thermoperiodic systems controlling the growth of different provenances of European conifers. It is quite likely that optimal growth and bud breakage are determined by night temperature in one provenance, by day temperature in others, and by the difference between the day and night temperature in still others as demonstrated for different coniferous tree species of North America. Finally, there may be provenances in which thermoperiodic growth control is absent and only photoperiodism operates. A set of 30 climates differeing with regard to photoperiods and thermoperiods are being used simultaneously in the phytotron for this purpose

Forsok med tallprovenienser med sarskild hansyn till norrlandska hojdlagen
[Text] = Experiments with provenances of Scots pine with special regard to high-lying forests in Northern Sweden : монография / E. Stefansson, M. Sinko. - Stockholm : Skoghogskolan, 1967. - 108 с. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 47). - swe. - Библиогр.: с. 104. - 2.60 р.
Аннотация: The results from the experimental area at Laxa could be interpreted as indicating that pine seed for use in Middle Sweden should be obtained from good stands farther north- as far as southern Norrland- however, the data are scanty, and should preferably be reinforced before more definite conclusions can be drawn. Where Inner Norrland was concerned, the investigation reemphasised the disirability of brining seed from the north for use in the south, rather than the reverse. By a process of "clearing" throughout Norrland from Norrbotten southwards, it should be possible to create favourable conditions for obtaining seed for reforestation at higher altitudes. A closer contact between the seed agencies concerned would improve the chances of satisfactorily solving the problem of seed supply until such time as the seed orchards can provide seed suitable for higher sites in larger quantities

Seed weight of larch from different provenances (Larix decidua Mill.)
[Text] = Frovikt hos lark av olika provenienser : научное издание / M. Simak. - Stockholm : Skoghogskolan, 1967. - 31 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 57). - eng. - Библиогр.: 27-29. - 0.10 р., 0.30 р.
Аннотация: European larch from different geographycal regions of its natural range of distribution varies in seed weight. These differences in seed weight are rather distinct, despite the fact that they have been found - as far as can be judged from the publication. The empty seeds, which usually have about 70 per cent of the weight of filled seeds, can influenece the thousand grain weight differently, depending upon the extent to which they occur in samples. However, it is rather difficult to separate empty and filled seeds of larch, owing to the small difference in their weight. For commercial separation of larch seed, special equipment has been constructed

Аннотация: Growth rhythm was related to latitude and altitude of seed source but not in the same way as suggested by previous studies. Variation in annual rhythm among seedlings within a provenance was considerable, and the height growth of the single seedling was correlated with rhythm.

Photo- and thermoperiodic responses of different larch provenances (Larix decidua Mill.)
[Text] = Foto- och termoperiodiska reaktioner hos olika larkprovenienser (Larix decidua Mill.) : научное издание / M. Simak. - Stockholm : Skogshogskolan, 1970. - 33 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 86). - eng. - Библиогр.: 28. - 0.30 р.
Аннотация: The investigation showed that there is an interaction between photo- and thermo-period which determines the plants' vegetative cycle. In comparison with the climate of the place of origin of the larch, in northern Scandinavia the days are longer and the temperature lower in the autumn. This is the reason why the introduced larch hardens poorly and too late, which in its turn makes it sensitive to early frosts.

Coastal and inland provenance trials in Pinus silvestris L.
[Text] = Proveniensforsok med kust- och inlandstall : научное издание / C.E. Ehrenberg, A. Gustafsson. - Stockholm : Skogshogskolan, 1971. - 36 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 95). - eng. - Библиогр.: с. 22. - 1.00 р.
Аннотация: Stands of Scots pine along the south-eastern coast of Sweden differ from inland stands at the same latitude as regards frequency of trees with broad crowns and crooked stems. In oder to investigate the nature and extent of the differences, a provenance trial was established with material of coastal and inland origin. The experimental design involved testings at two sites (coastal and inland), at two spacings at each site and with two methods of establishment (sowing and planting). Differences between provenances were established as regards germination, survival, occurrence of prolepsis and some blanching characteristic. Inland pines were less well adapted to coastal conditions than were coastal pines to inland environment. Different methods were demonstrated.

Аннотация: In the present investigation an attemp was made to the effect of different temperatures on the pattern of meiotic development as well as the effect of a below zero temparature on the induction of irregularities. Experiments were carried out under controlled temperature conditions in a climatic cabinet on Norway spruce of both Swedish and introduced provenances. The different origin of the material also allowed one to investigate whether or not the origin affected the temperature response of PMC

Аннотация: In the present study attention has been concentrated on the pathogens of lodgepole pine. The susceptibility to attack by various pathogens of ca. 100 different provenances of Pinus contorta (ca. 25 000 plants) in northern Sweden has been studied over periods of three to nine years. Due to the design of trials, only a small number of Scots pine provenances were included.

Кл.слова (ненормированные):
basic density -- variation -- tracheid length -- transfer -- spacing -- provenance
Аннотация: The aim of this study is to describe the magnitude and sources of provenances variation in wood density and tracheid length in Sweden. The study indicates that changes in forest management and forest tree breeding are needed in order to increase basic density and fibre length. Basic density and tracheid length were assessed in 67 provenances from one or more of 18 provenance traials at the age of 30 years. From each provenance and trial 10 trees were sampled from a 1.25 metre spacing and 10 trees from 2.0 metre spacing whenever possible. Assessments were made at growth rings five and ten respectively from the bark for basic density and at growth ring five from the bark for tracheid length.
