A geometric modeling of tracheal elements of the chard ( beta vulgaris ) leaf

Abstract

In this study, we give a geometric description of the tracheal elements of the chard (Beta vulgaris var. cicla L.). which is a widespread cultivated plant in Turkey. It is used as an edible plant and its leaves are used as antidiabetic in traditional medicine plant. We have shown that the tracheal elements, which are taxonomic value of the plant, can be considered as a surface of revolution or a tubular shape along a special curve.
