Abstract
In the last two decades, Taxus baccata was the subject of numerous studies that have focused on
chemical and biochemical aspects, also because of the notoriety paclitaxel (a brest-cancer
antitumoral).
This sudden interest in a plant that has long been scientifically neglected, allowed to focus attention
to a research area on which there is still much to discover. Among the many studies on the yew, is
only mentioned the study of fundamental aspects such as dendrological and dendrometric.
Even less interesting, appears to be the study of his sexual expression. Was necessary to make these
premises, in order to explain why such a simple methodological approach as what follows will be
exposed, is in fact new in the study of Taxus baccata. In this study, we pay attention to the structural
differences between the sexes, sexual expression and the influence of the environment on the sex
change in T. Baccata.
The choice of the study sites has been essential to highlight the differences between populations, in
particular those ones ecological (the stands are located in several places of Italian peninsula and
in Sardinia island).
The study concludes with a proposed of a original model to explain the sexual expression in yew .
