English title: Observations on the soil frost of the winter 1941-1942.
Original keywords: Bodenfrost; Formation
English keywords: soil frost; formation

Soil frost from the winter 1941-1942 was of a special form. To create such a strong soil frost there need to be capillary soil form and long period of permanent and intense cold, meaning minus temperatures.  The frost layer was thicker than normally.

Such a frost causes many problems on the fields and roads when the soil rises because of the frost and then falls unevenly back when the frost melts.

English title: Morphologic interpretation of a spruce cone based on fertilization.
Original keywords: Fichte; Zapf; Fertilisation; Morfologie
English keywords: spruce; cone; fertilization; morphology

Article presents some rare cone formations found from a small spruce in region of Punkaharju, Finland. In this case all the scales have developed into perfect, green needle leaves. Instead of a normal scale of a cone there are formations of buds that on the basal part of a cone resemble a normal bud, and hence develop into a branch. On the upper part of the cone formation the bud develops into scale of a cone.

The morphological form of the cones has been interpreted many ways. These anomalies resemble earlier observations and hence support the former theory of inflorescence. According the theory, the scales and scales of a cone are separate leaves, the scale corresponding to one leaf, the scale of a cone corresponding to two leaves. A cone is hence rather to be compared with a branching inflorescence than only one flower.

English title: The effect of the amount of the summer wood on the elastic and tensile properties of coniferous trees.

The dependence of elastic and tensile properties of coniferous trees on the share of summer wood can be presented as linear functions, if the soft wood is considered as a statically indefinite structure. By eliminating the share of summer wood by a certain function presented in the article, the elastic and tensile properties are the linear functions of density.

The functions are proved right by conducting strength tests on pine. Practical implications of the derived functions in rating the quality of wood are also presented.
