“…In the studied forest, Le Tacon and Oswald [24], had found falls of beech mast of 186.5 kg/ha/yr in a 140-year-old stand, and of 86.5 kg/ha/yr in a stand of the same age in the Vosges but on a less fertile soil. It is difficult to obtain mean values because of the high annual variability, so it is more relevant to compare fertile years.…”

-Litterfall is the first phase of the biogeochemical cycle and returns nutrients to the soil. This paper demonstrates the quantitative distribution of the different components throughout the year in four stands of a beech time sequence. Litterfall increases as the forest evolves and as basal area increases: from 2.1 t/ha/an in the thicket to 4.7 t/ha/an in the mature high forest. Leaves represent 90% of the total litterfall in the young stand and 70% in the oldest stand. The proportion of leaves decreases during forest rotation. Most of the categories are related to the age and basal area, because of the architecture and maturity of the trees. Other factors could explain litterfall dynamics, e.g. human management or animals. Climate is a preponderant factor for the litterfall production and plays a role in the species phenology. The litterfall dynamics during the time sequence, and the observed shifts in phenology give rise to different pedogenetic processes.litter production / beech / time sequence / dry matter Résumé -Production de litière dans une chronoséquence d'une hêtraie (Fagus sylvatica) atlantique. Les retombées de litière sont à la base des cycles biogéochimiques et assurent le retour au sol des nutriments. Cet article présente la répartition quantitative, par compartiment, au cours de deux ans de suivi et dans quatre peuplements de hêtre d'une chronoséquence. Les retombées totales de litière augmentent avec l'âge de la parcelle et la surface terrière : de 2,1 t/ha/an dans le fourré à 4,7 t/ha/an dans la vieille futaie. Les feuilles représentent 90 % des retombées totales dans le jeune peuplement et 70 % dans la parcelle âgée. La proportion de feuilles diminue au cours de la chronoséquence. La plupart des catégories sont reliées à l'âge et à la surface terrière, par l'intermédiaire de l'architecture et de la maturité du peuplement. D'autres facteurs peuvent expliquer la dynamique des retombées: la sylviculture, les animaux. Le climat est un facteur prépondérant dans la production de litière et a un rôle également sur la phénologie des espèces. La dynamique des retombées de litière au cours de la chronoséquence ainsi que les décalages phénologiques observés sont à la base de processus pédogénétiques diffé-rents.hêtre / retour litière / chronoséquence / matière sèche Ann.

“…Holmsgaard and Bang, 1990;Hilton and Packham, 1997;Schmidt, 2006;Ö vergaard et al, 2007, and references therein). This increase may be related to the higher frequency of warm periods and to the effect of higher nitrogen availability through atmospheric deposition (Falkengren-Grerup and Eriksson, 1990;Callesen et al, 2007) or direct fertilization of forest stands (Le Tacon and Oswald, 1977). Increased masting frequency could benefit practical forestry since it improves chances for successful regeneration of beech stands.…”

“…Root pruning has also been used to enhance flowering Webber et al 1985), as has root flooding (Bonnet-Masimbert 1982). The relationship with stress is not applicable to nutrition: fertilisation of trees results in increased flowering and cone or cupule production (Le Tacon et al 1977;Mikola 1987;Wesoly et al 1987). If this is the case, then it might be expected that trees showing previous signs of stress would show greater levels of fruiting in years of fruit production.…”

Summary. The level of fruiting in four forest trees species(Picea sitchensis, P. abies, Pinus sylvestris and Fagus sylvatica) was monitored in Great Britain over the period 1989-1991. In addition, assessments of crown transparency were available for many of the trees for 1987 and 1988. The monitoring period encompassed severe summer droughts in 1989 and 1990, with wetter conditions in 1991. Variations in the level of fruiting in spruce and beech (Fagus sylvatica L.) were seen, with a marked peak in 1990. No pattern was apparent in Scots pine (Pinus sylvestris L.). Coning, which was greater in trees with the least transparent crowns, had no discernible effect on the crown transparency of the conifers. Cupule production in beech was greatest in trees with the most transparent crowns, and trees with high numbers of cupules in 1990 tended to have greater crown dieback recorded in 1991.
