English title: Significance of the bird-cherry (Prunus padus L.) for the occurrence of the rust, Puccinastrum padi (Kunze & Schm.) in spruce.

The present study deals with the occurrence of the rust, Pucciniastrum padi (Kunze & Schm.) Diet., in the shoots and cones of Norway spruce (Picea abies (L.) H. Karst.) in the forest area of the training and experimental farm of Helsinki University at Viikki (60’10’ N; 25’ E). The most important task was to clarify the correlation between the occurrences of the disease in spruce and the abundance of the alternative host of the disease, bird-sherry (Prunus padus L.).

Infected shoots were encountered in a 17-year-old planted seedling stand of spruce. In this stand 8.4% of the seedlings were infected. The density of bird-cherry trees was in the stand higher than in the surrounding areas. The number of infected shoots was the greatest in those places where the density of bird-cherries was highest and already at a distance of some ten metres form the bird-cherry stands the degree of infection decreased considerably. The portion of infected cones in the whole material of this study was 19.5%.

The dependence of the frequency of disease on the abundance of bird-cherries at different distances from the spruce stand was studied by means of regression analysis. For this reason, the percentage infected cones were determined by sample plots and the abundance of bird-cherry trees from six zones (0–50, 50–100, 100–150, 150–200, 200–300, and 300–500 m) around each sample plot. The results showed that the dependence between the degree of infection of cones and the abundance of bird-cherry in the surroundings only reached the closest zone. There were also infected cones at greater distance, for instance, 200–300 m from the bird-cherries about 10% of the cones could be infected. Both the infected cones and shoots were longer than the healthy ones.

S. A. Wilde. (1967). Production of energy material by forest stands as related to supply of soil water. Silva Fennica vol. 1 no. 1 article id 4737. https://doi.org/10.14214/sf.a14447

This study estimates the supply of soil water required for the annual and total production of energy material by the biomass of 32-year-old plantation of red pine, Pinus resinosa Ait. in Wisconsin, the United States.

The supply of transpiration water was determined as the sum of summer precipitation, winter stored water, and condensed vapor, minus gravitational discharge and evaporation of intercepted rainfall. On the average, the 1,20 m root zone of coarse sandy soils of central Wisconsin receives 2,750 M.T. of water per hectare. During the 32nd year of plantation growth, the increment biomass, including 43% of merchantable timber, was 10,100 kg/ha, or 162 x 105 kcal/g. At this time of the culminating growth, the production of 1 kg of wood material consumed 272 kg of water. The corresponding transpiration coefficient 0,37% is near the maximum for the ecosystem of hard pines – sandy soils of glacial outwash with field capacity between 7 and 9%. On the weight basis, the annual leaf fall constituted 32% of the biomass and over 80% of merchantable timber.

The entire supply of water of 96,000 M.T./ha produces in 32 years 211,112 kg of total dry matter at a rate of 1 kg of wood per 455 kg of water, with corresponding transpiration coefficient of 0,22%. The evapogravitational losses during the early stages of the stand’s growth decreased the water utilization efficiency of trees about 40%.

The information obtained permitted to outline several hydrological relationships pertinent to forest culture, namely: maximum rate of forest growth as delineated by the supply of available transpiration water; content of available moisture in soils of high tension capacity; contribution to soil water rendered by natural subirrigation and condensation of athmospehric vapor; growth depressing effect of weeds.

English title: Potential in using determination of insect species breeding in the logging residue to estimate the time of the logging.

Degree of decomposition of logging residue, and decay in stumps have been used in forest inventories to estimate the time of the felling. In this paper, a method was developed to use insects breeding in the logging residue to determine how long ago the felling took place. The method is based on the arrival and rate of development of the different species of bark beetles that breed in the logging residue.

The most suitable insect species to be used in the purpose of timing the age of logging residue were defined, and their occurrence in different tree species and fellings performed at different times of the year were described. The species can be easily identified by gallery systems characteristic to the species.

It is concluded that the method does not suit for broadleaved species, because there is no common insects suitable for this purpose. Also, the time of swarming of the insects depends on the weather conditions in the spring, which makes it difficult to give definite dateshe progress of the spring has to be taken into account when the occurrence of the insects is used in the determination of the time of the felling. In addition, local conditions, such as shading, affect drying of the branches, and can influence the occurrence of the insects. For Scots pine and Norway spruce the age of the logging residue can be determined precisely only at most two years back.

English title: Publishing activity of the Society of Forestry in Finland.

The paper includes a short description on the publishing activity of the Society of Forestry in Finland (now the Finnish Society of Forest Science), founded in 1909, and describes the changes in the publishing of the series Acta forestalia fennica and Silva Fennica in 1967. The series Silva Fennica was changed into a quarterly starting from the beginning of 1967, at the same time, the principles of publishing was changed at least in part in favour of short reports.

The article includes an abstract in English.
