Studies on European beech (Fagus sylvatica L
Colour parameters of European beech were measured using CIELab system. 103 logs from 87 trees in 9 sites were cut into boards to study the variations of wood colour parameters. Both site and tree effect on colour were observed. Patterns of red heartwood occurrence were defined. When excepting red heartwood there was still a highly significant effect of site and tree; differences remained after ...
متن کاملPredicting red heartwood formation in beech trees (Fagus sylvatica L.)
Beech-forests (Fagus sylvatica L.) represent the natural vegetation cover for the majority of sites in Germany. Although coniferous forests actually dominate, beech is the most important among the deciduous tree-species in Germany, when considering the area and the economics. While the wood of the younger beech normally shows a whitish colour (white beech), the timber of older beech may form co...
متن کاملInfluence of site conditions on the survival of Fagus sylvatica seedlings in an old-growth beech forest
Following a full mast production in autumn 1995 in the old growth beech forest of la Tillaie, France, cupules, live and dead yearling seedlings were counted in September 1996 in 40 plots, embracing a wide range of ecological conditions. The influence of geomorphology and forest stage on mast production and on seedling establishment and survival was studied. Maximum seedling abundance did not oc...
متن کاملRoot biomass and biomass increment in a beech (Fagus sylvatica L.) stand in North-East France
This study is part of a larger project aimed at quantifying the biomass and biomass increment of an experimental beech stand aged 30 years, and comparing the carbon sequestration in trees to carbon fluxes. The below ground part of trees is expected to play an important role in carbon sequestration. A method has been developed to estimate the biomass and biomass increment of coarse, small and fi...
متن کاملParametric identification of a functional-structural tree growth model and application to beech trees (Fagus sylvatica)
Functional-structural models provide detailed representations of tree growth and their application to forestry seems full of prospects. However, due to the complexity of tree architecture, parametric identification of such models remains a critical issue. We present the GreenLab approach for modeling tree growth. It simulates tree plasticity in response to changes of their internal level of tro...
