Аннотация: When establising young plantations, certain courses are taken which in the future will have a susbstantial influence on the volume and quality production, on the total expenses and the forest rent as well as on stand safety. The type and the quality of stock and the spacing are of particular concern for the artificial regeneration of Norway spruce. By comparing informative results found in literature and in light of the institute's own research projects, this book endeavours to serve as a directive for forest planning and forestry practice

Аннотация: With one exception German thinning rules have always been aimed at selecting individuals of desirable properties and removing one by one their surrounding neibours even if these are just as valuable. In the framework of this approach a symmetrical crown-extension of the prospective crop trees is a major concern. All this amounts to a "spacing thinning". As opposed to selection thinnings which enforce upon heterogeneous stands very schematic ditribution patterns, group thinnings allow for a much more flexible adaptation to the special conditions of each stand when entering thinning age. - Some preparatory comments were made on the question to what extent other tree species and other constellations offer themselves for group thinnings. One can hope that the specialists of growth science and wood technology will now put the assumptions on which selection thinning and group thinning are based to a vigorous test

Аннотация: The book consists of two parts. Part I deals with the silvical basis for seeding and planting, more particularly the principles which underlie the choice of species, the closeness of spacing, and the composition of the stand. Part II is descriptive of the various operations in artificial regeneration and the results that may be expected from the best practice.

Аннотация: The third edition of this book deals with the production of nursery stock for planting on particular sites and the inauguration of greatly enlarged planting programs by federal, state, and private agencies. In this edition, very few cost figures are included for the various nursery and planting operations. In preparation of this edition, many helpful and constructive suggestions have been received from a number of American foresters.

Аннотация: In this paper the author described the results of the studies on the external appearance of Sugi stems from the sample plots established in Yoshino, Nishikawa, Nakoso and Obi districts as they represent the Sugi forest grown with typical different silvicultural treatments. Outline of the sample plots is shown in Table 1. Results are as follows: 1. The coefficients of variance of the tree height in sample plots appears to become larger as spacing density of the plantation decreases (Table 6). 2. The height of trees from Nishikawa is significantly lower than that of all others under 20 years, and that of trees from Obi is significantly taller than others above 20 years. 3. The coefficient of variance of the breast height diameter of sample trees in the sample plots is minimum for the trees of Obi districts where the plantation spacing is the widest (Table 7). 4. The relation between tree ages and b. h. d. of sample trees. The b. h. d. of sample trees at the same age classes appears to become larger as plantation spacing widens (Fig. 3). 5. The range of variance of the relation between height and b. h. d. of the sample trees appears to become considerably narrower as the spacing of trees in forest widens, and in Obi districts these relations are considerably different from those in others (Fig. 4). 6. The degree of full-body of sample trees in different sample plots appears to be smaller as plantation spacing widens, but the effect on its variance within sample plots is not clear (Table 8). 7. The degree of full-body of sample trees rapidly decreases as tree age increases under 15-20 years, but beyond this critical age it is observed that degree of full-body remains almost constant in Yoshino and Obi, and that it increases slightly in Nakoso and significantly in Nishikawa respectively as tree age increases (Fig. 5). 8. The clear length and the percentage of clear length to tree height in the sample trees seem to become larger as plantation spacing narrows, but it is contrary in the case of the coefficient of variance for the percentage of clear length to tree height. 9. The percentage of clear length to tree height of sample trees generally tends to be larger at the same age classes as plantation spacing narrows (Fig. 8).

Аннотация: Crown stem measurements were taken periodically on selected trees in plantations of red pine (PINUS RESINOSA AIT.) over the period 17 to 37 years from seed. Spacings were 5x5, 7x7, 10x10, and 14x14 feet; some of these represented the original planting interval and others had been achieved by mechanical thinning at the start of the experiment. Little mortality occurred during the 20 years, and individual crown size tended to stabilize, with smaller crowns occurring with closer spacings. Periodic volume growth per acre was strongly correlated with average foliage weight for the period. Thinning was followed by an immediate but temporary increase in foliage ranged from 0.023 to 0.038 cubic feet. Crown length, width, and weight, once stabilized, did not show good correlation with parameters of individual stem growth which are cumulative. Height to crown continued to increase and was strongly correlated with total volume per acre and with the ratio average height average spacing. Breast-height growth of sample trees appeared to be a function of height to crown and foliage weight.

Аннотация: Timber quality in Scots pine (Pinus sylvestris L.) stands in Sweden has deteriorated during the 20th century. A possible cause of this is the increasing proportion of timber that originates in planted stands. Two naturally regenerated and two planted pine stands, of the same genetic origin, were compared. The planted stands were established as spacing experiments (1.25 x 1.25-2.5 x 2.5 m) at Tonnersjoheden Experimental Forest (lat. 56 grades 42'N, long, 13 grades 06'E, alt 60 m). Volume growth and timber quality, i.e. taper, crookednees, number of branches, branch thickness, branch angle, crown size, occurrence of spike knots and damage were compared. The quality of dominant and co-dominant trees was higher in the naturally regenerated stands than in the planted stands. Of the planted trees, only 25% were straight, compared with 86% of naturally regenerated trees. In the planted stands, the mean diameter of the thickest branch below 2m was 23 mm, compared to 15mm inthe naturally regenerated stands. Timber quality and planting density were also positively correlated, quality being very poor at the widest spacings. Volume growth at initial spacings of 1.75 x 1.75m and denser was estimated to be 5-10% higher than that in the naturally regenerated stands.

Аннотация: Seedlings of larch, pine and spruce were grown in darkness and some of them were illuminated for 24 or 48 hours. Chloroplast differentiation in cotyledons of these seedlings was investigated by electron microscopy. In the larch the dark-formed chloroplasts have immature lamellar systems with minute grana formed by 2-3 thylakoids. In the pine the diameters of the grana are much larger but they are still formed by only 2-4 thylakoids. Corresponding spruce chloroplasts have advanced lamellar systems with large grana containing up to about 10 thylakoids. Chroplasts of larch and pine have a few large prolamellar bodies with a more or less narrow spacing of their structural units, while spacing or a combination of both. All three species have large starch grains in their chloroplasts. After 48 hours of illumination the conifer seedlings posses mature chloroplasts with many prominent grana. Prolamellar bodies are only found in a small fraction of the larch chloroplasts. Chloroplast strach grains are common in the spruce, but rare or absent in the other two speies.

Аннотация: An experiment was made with grafts of four different clones of Scots pine planted in 1963 in poor sandy soil, with two different spacings and with and without an annual supply of fertilizers from 1964 onwards. The nutrient status of the pines was followed by foliar analysis of needles sampled every autumn. Measurements of a great number of traits were made in 1967 and 1969 and subsequent statistical anlyses showed that both clones and treatment had significant effects on tree properties. Fertilizer strongly affected many properties, such as diameter, branch length, and diameter, cone setting and needle length.

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.

Аннотация: The study is based on a series of trials of which the southern trials were earlier analysed. This makes it possible to compare the present results wth those of the previous study. The general models for geographical variation indicate that the highest nimber of straight stems without spike knots may be found between latitudes 58 degrees and 65 degrees N and altitudes below 250 m.
