    Opis:
    Beech is an important woody species in terms of ecology, and it also has a considerable commercial value. This fact is also reflected in a high number of scientific papers handling the issue of natural regeneration of this woody plant. The aim of this review is to analyse influence of resources availability and impact of other factors (competition) on height and diameter growth, survival, density, biomass partitioning and morphological adjustment in naturally regenerated beech seedlings and saplings. It pays a particular attention to light – the factor that influences, directly or indirectly, other environmental factors, and consequently, as the key influence on the performance of beech natural regeneration. This contribution includes information about e.g. shade tolerance and mortality-light relationships, ability to increase growth under improved light conditions, dependence of trees growth on their individual size and age etc. In spite of a large number of papers handling the issue of research on beech natural regeneration, growth responses in individual plants are difficult to predict, because the factors involved are numerous. Thus, the process of natural regeneration is in fact interactive, and even retroactive: any change in one of the involved factors induces adjustments of the others.

    Opis:
    The present study was aimed to find out whether the preformation of future shoot’s organs within a bud is reflected in the bud size/shoot functional traits’ size relationships. The survey attempts to evaluate whether relationships between the bud mass and stem mass, leaf mass, leaf area, total mass and number of leaves, respectively, of spring-shoot sprouted by the bud in Fagus sylvatica (L.) saplings are affected by parental bud location within shoot and parental shoot type. Dry mass of the terminal bud, the first and the last lateral buds placed on terminal and uppermost lateral shoots was estimated nondestructively for 58 beech saplings in December 2008. The shoots sprouted from the measured buds were sampled at the end of growing season, in August 2009. Bud mass, parental shoot type and bud location explained about 90% of shoot traits variability in full-factorial ANOVA. The leaf mass was the only shoot trait not affected by parental shoot type and bud location within shoot in scaling relationship with bud mass. There was not found differences among intercepts across parental shoot types and bud locations, however significant shift along common slope was observed among them. The presented findings could be viewed as a confirmation of the preformation and full development of leaf primordia within the European beech buds prior to bud burst.
