Calcium Oxalate Crystal (CaOx) Composition at Different Growth Stages of Petiole in Vitis Vinifera (Vitaceae)

Abstract

Most plants accumulate inorganic inclusions called calcium oxalate crystals (CaOx) in both vegetative and reproductive organs. In these studies, the similarities and differences for the type and distribution of calcium oxalate (CaOx) crystals were examined in both young and mature petiole Vitis vinifera L. (Vitaceae). Transverse, radial, and tangential sections were obtained from epidermis, cortex, xylem and phloem tissue of different specimens. Crystal measurements of young and mature petiole were statically analyzed. Significant differences were determined between young and mature petiole in terms of distribution in the tissues and varieties of crystal.
