A geometric description of the peritechia of the Pseudonectria rousseliana (Mont.) Wollenw

Abstract

In this study, a geometric and experimental analysis of the peritechia of Pseudonectria rousseliana (Mont.) Wollen was presented. Experimentally, longitudinal length (A) and the body ( CD ) of peritechia were measured. Geometrically, it was shown that the peritechia is comparable with a surface of revolution of a profile curve. On the same regions of the modelled surface the diameters of the horizontal sections was measured. It was found that the geometric and the experimental values were closely related.
