Title Calcium Oxalate Crystals in Pistils and Stamens of Some Angiosperm Taxa
Authors Sevil TÜTÜNCÜ KONYAR, Feruzan DANE
Abstract Calcium oxalate crystals that are present in almost all parts of the angiosperms have different morphological forms: as druses, prism, styloids, raphides and crystal sand. In the present study, occurrence, types and distribution of calcium oxalate crystals in the pistil and stamen of four angiosperm taxa including Sternbergia lutea (L.) Ker-Gawl. Ex Sprengel, Bellevalia edirnensis N. Özhatay & Mathew, Trachelium jacquinii (sieber) Boiss. subsp. dalgiciorum N. Özhatay & Dane and Cyclamen coum Miller. were investigated with light microscopy using paraffin and handmade sections. During the study, special attention was given to reveal the presence and absence of crystals in the stigma, style, ovary, anther and filament at different developmental stages of the pistil and stamen. To observe the crystals at different stages of another development, buds at different phases of microsporogenesis, and microgametogenesis were used. Two types of calcium oxalate crystals were identified in the examined plants. While raphide crystals were observed in S. lutea and B. edirnensis, druse crystals were observed in Cylamen coum and T. jacquinii subsp dalgıciorium. At the end of the study, it was concluded that presence and distribution of calcium oxalate crystals in the pistil and stamen depends on the developmental stages of the male and female organs.
