Calcium oxalate crystals in generative organs of Astragalus hamosus and Astragalus glycyphyllos

Bu çalışmada, Astragalus hamosus L. and Astragalus glycyphyllos L. un generatif organlarındaki kalsiyum okzalat kristal tiplerinin dağılımı ışık mikroskobu kullanılarak incelenmiştir. A. glycyphyllos taki sitoembryolojik çalışmalar boyunca generatif organlarda CaOx kristalleri gözlenmiştir. A. hamosus ta gözlenmediği halde A. glycyphyllos un çiçeklerinin farklı bölgelerinde prizmatik ve druz tip kristaller gözlenmiştir. Bu çalışma incelenen Astragalus türlerinde CaOx kristallerinin varlığını göstermektedir.

Astragalus hamosus ve Astragalus glycyphyllos generatif organlarındaki kalsiyum okzalat kristalleri

In this study, distribution of Calcium oxalate (CaOx) crystal types within generative organs of Astragalus hamosus L. and Astragalus glycyphyllos L. and crystal types of them were examined using light microscopy (LM). During cytoembryological studies on A. glycyphyllos, CaOx crystals have been observed in generative organs. Prismatic and druse type crystals were determined in different regions of flowers of A. glycyphyllos while were not observed in A. hamosus. This study represents additional data on the presence of CaOx crystals in examined Astragalus species.
