Abstract

Growth is analysed both in ordinary and twisted beeches located in Verzy near Reims, France. Most variables of annual and multiannual growth are the same in the two types of trees. Stems in the twisted tree are markedly sinuous from the moment they begin to develop and remain so, whereas in the ordinary tree the sinuosities are attenuated and thenthe stems are straightened, right from the first years of development. In the ordinary tree, the straightening of the stems is regulated atthe level of the ramified branches and the crown; this regulation establishes a strict hierarchy among the stems according to the order of the stems in the ramification. However, in the twisted beech, this regulation is absent and consequently sinuous stems are riot straightened, lateral stems stand up, and reiterations start. Therefore, the frameof the ordinary tree is simple and only composed of one morphogeneticsequence before metamorphosis whereas frame development in the twisted tree consists of several sequences.
