Araceae Familyasına Ait Arum nickelii Schott ve Monotipik Arisarum vulgare O.Targ.-Tozz Türleri Üzerinde Morfolojik ve Anatomik bir Araştırma

Bu calismada Araceae familyasindan olan Arum nickelii Schott (Yilan yastigi) ve Arisarum vulgare O.Targ.-Tozz (Yilancikotu) turlerinin anatomi ve morfolojileri arastirilmistir. Incelenen turler spatanin birlesik olup olmamasi bakimindan birbirinden ayrilir. Anatomik calismalarda parafin metodu kullanilarak hazirlanan kok, skap ve yapraklar safranin-fast green ikili boyama serisinde boyanmistir. Anatomik olarak tipik monokotil ozellikleri gosteren bitkilerin diger Araceae turlerinden ayirt edici bazi ozelliklere sahip oldugu belirlenmistir. Bu farkliliklar orijinal cizim ve fotograflarla gosterilmistir.

The anatomical studies on two Biarum (Araceae) species in Turkey

In this study, anatomical properties of Biarum marmarisense (P. C. Boyce) P. C. Boyce and Biarum pyrami (Schott) Engl. var. pyrami were examined. The specimens were collected from Antalya province, South West of Anatolia. Degree of spathe tube margin connection, distribution of pistillodes and staminate-pistillate flower zone interstice length characters are important in Biarum Schott. taxonomy at specific level. The cross-sections of root, stem and leaf parts of the plant were examined and demonstrated by photographs. Although thicknesses of the cell wall of the endodermis and xylem strands are distinguishing features, raphide crystals are same feature in both species. B. marmarisense has observed paracytic stoma types while B. pyrami var. pyrami has anomocytic stoma types. Most of the anatomical properties were similar to the other members of the Araceae family.

Cytological study on Hippocrepis ciliata L. and Hippocrepis unisiliquosa ssp. unisiliquosa L. (Leguminosae) in Turkey

Somatic chromosome numbers and karyotype of Hippocrepis unisiliquosa ssp. unisiliquosa L. and Hippocrepis ciliata L. (Leguminosae) collected from Turkey were examined. Chromosome numbers were determined as 2n = 2x = 14 in Hippocrepis unisiliquosa ssp. unisiliquosa L. and Hippocrepis ciliata. The mitotic chromosome number and karyotype of the taxa were reported here for the first time.
