Аннотация: Results are presented from a study concerning the influence of environmental factors on the formation of summer shoots in young plants of Pinus silvestris L. grown in plastic green houses. A close relationship is found between the studied factors: CO2, water, nutrients and the occurrence of summer shoots. Poor environmental conditions during the first year followed by improved conditions in the following year resulted a great number of plants with summer shoots, whereas favourable conditions during the first year resulted in a low number of plants with summer shoots the following year. According to these results the conclusion is drawn that environmental conditions and especially those of the preceding year have a great influence on the formation of summer shoots and on the shoot growth as well.

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: Effect of fertilization on the incidence of summer shoots, nutrient concentration and morphology of bare-root pine seedlings was studied in two nursery experiments during two successive years. In both experiments three levels of top-dressing fertilization were studied, as well autumn fertilization and maintenance dressing before transplanting. Seedlings grown in two nursery experiments were planted and their performance was monitored 7-8 years after planting.
