Аннотация: Effects of fertilisation treatments (amounts and composition) on needle concentrations of micronutrients (boron, copper, iron, manganese and zinc), were studied in a long-term fertilisation experiment with young Norway spruce in Central Sweden. Stored current-year's needles (1967-1989), and material from a biomass sampling in 1989, were used to determine changes in micronutrient status with stand development, and to estimate total amounts of micronutrients, in all aboveground organs for a wide range of nutrient regimes and stand productivities. Fertilisation resulted in a wide range of growth rates: the most optimal treatments grew more than three times as fast as the control stands.

Аннотация: This publication describes common fungal diseases of Russian forests, including diagnostic signs and symptoms, pathogen biology, damage caused by the disease, and methods of control. The fungal diseases are divided into two groups: those that are the most common in Russian forests and those that are found only in Russia. Within each group, diseases are subdivided by plant organ attacked, i.e., fruit, seeds, leaves, needles, roots, stems, and branches.

Аннотация: The procedure is based upon X-ray fluorescence, and has been found very suitable with a largr number of samples. The results of analysis indicated that pine needles and birch leaves contain chloride in no more than negligible amounts. The highest percentages of sulphur encountered in pine needles were less than one half of the amount considered dangerous (0.5 per cent), and practically the same as those derived ealier in the vicinity of soidium sulphite pulp mill in Ornskoldsvik, Sweden. Similar mean values were found for the total sulphur in pine needle samples collected from Lahti and from the central area of Rauma town locating about two kilometers to the north and north east from pulp mill

Аннотация: The influence of growing conditions upon pigmentation in needles from seedlings of Scots pine and Norway spruce has been studied. The plant material was grown either in the open or in plastic greenhouses. A pronounced seasonal variation of both chlorophyll and carotenoids was found. The content of pigments was influenced also by growing conditions, plant age, needle age and origin of the seed source. The new technique of growing coniferous seedlings in greenhouses during the vegetation period does not have any harmful effect upon the seedlings, as far as the pigmentation of the needles is concerned.

Аннотация: The present investigation is part of a research ptoject concerning the physiological and structural background to resistance in pine (Pinus silvestris) against the rust fungus Peridermium pini (Nyman et al. 1973). One of the approaches to this project is to use electron microscopy for studies of cellular interactions between susceptible and resistant host needles on one hand and invanding mycelia on the other hand. Several methods of preparation of this technically difficult materials were used.

Аннотация: The aim of the present study has been to evaluate the extension of eventual influences on the surrounding vegetation of the emission from the iron-sintering plant in Sweden- in close proximity to the communities Koskullskulle, Malmberget and Gallivare. The yearly emission of sulphur dioxide and hydrogen fluoride has been around 2000 ton and 175 ton, respectively for the last years. The content of sulphur and fluorine in the needles of Scots pine from the sample plots has been analysed and correlated to the emission source. The needle drop of coniferous trees, well-known from air polluted areas, has been quantitatively recorded and correlated with the occurrence and physiological reactions in some lichen species from the emission source.

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 the present work was to investigate the effect of mineral nutrition on frost hardiness. Frost hardiness in Scots pine with different concentrations of mineral nutrients in the needles was determined during winter by different freezing treatments. For the determinations, needles from a fertiliser experiment in central Sweden were used. The main effect of fertilisation on nutrient concentrations in the needle was on nitrogen, which showed a marked responce to treatment. Frost hardiness determinations were made by measuring the leakage of electrolytes from the needles. With freezing treatmen ts that caused heavy damage, there was a maximum hardiness at nitrogen concentrations of between 1.3 to 1.8 % dw, whilst with moderate damage, no such maximum could be detected. In this case, a tendency towards decreasing hardiness with incresing nitrogen concentration was observed.

Аннотация: The study had three aims: 1. Todescribe a procedure for measuring basic needles dimensions on transverse sections, and to assess sources of error associated with it. 2. To discover to what extent the application of mineral nutrients affects the basic dimensions of Scots pine needles. 3. To establish relationships between a radily measured character, such as needle length, and the volume, total and projected area of individual needles.

Аннотация: The effect of single and repeated fertilization on the nutrient status and stemwood growth of Scots pine on drained peatlands was investigated in the study. The magnitude of the growth increment obtained with single fertilization depended on the nitrogen content of the substrate. On nitrogen-poor peatlands (N content of the surface peat below 1.75 %) P- fertilization increased the volume growth of pine during the 7-year period by only 0.2-0.3 m3/ha/a. The effect of NPK was at its greatest 3-5 years after fertilization, and gave a measurable stand growth increase for about 10 years. The effect of fertilization was reflected in the needles as slightly elevated P and K concentrations.
