Experience with establishment and cultivation of Scotch pine stands
of the first age degree

In the paper the partial results of research project called Establishment and cultivation of pine stands of the first age degree in ecotopes disturbed by human activity (subproject: Definition and quantification of injurious and stressing factors in Scotch pine stands of the first age degree in changed immission and site conditions of east part of the Elbe River Region) are presented. The thema of the subproject comes from an actual health stage and development of young Scotch pine stands (Pinus sylvestris L.) in the East Bohemia. During 1992 - 1998, many deviations and malformations were observed, e. g. big differentiation of height growth, reduction of stand density, mortality of trees after infection by Armillaria mellea sp., deviations from standard habitus of the Scotch pine (form deformations of the stem and crown), colour changes of needles, anomalies in growth of buds, shoots and needles, late seasonal (summer, dicyclic) growth of Lammas shoots and proleptic shoots, etc. The aim of the work was to characterize the dynamic of height growth in pine forest stands of the first age degree, the dynamic of Scotch pine mortality after attack of Armillaria ostoyae (Romang.) Herink, the nutrition status of young pine stands in forest territory called Bory, the development of colour changes of needles and the frequency of the growth disturbance in pine plantations. The research was performed twice in the period 1992 - 1998 on 387 sites in a young (1 - 13 years old) pine stands of east part of the Elbe River Region.
