Karyotypic study on Silene, section Lasiostemones species from Turkey

Abstract Karyology of the eight taxa of section Lasiostemones from Turkey was investigated. Diploid chromosome numbers and the basic chromosome number of the studied taxa were obtained as 2n=24 and x=12 respectively. The karyotype analysis of studied taxa was carried out and chromosome number of S. capitellata, S. lasiantha and S. manissadjianii were determined at the first time. The largest chromosomes were observed in S. capitellata and the smallest ones were observed in S. isaurica. S. capitellata shows the highest A1 index. S. olympica represents the highest interchromosomal asymmetry coefficient (A2). The karyologic results of the study and the analysis of chromosomal morphology of each taxon were shown as tables.

Proximate composition, antimicrobial and antioxidant activities of six wild edible celeries (Smyrnium L.)

In this study, proximate composition, antimicrobial and antioxidant activities of six Smyrnium taxa, including, Smyrnium olusatrum , Smyrnium perfoliatum , Smyrnium rotundifolium , Smyrnium cordifolium, Smyrnium connatum and Smyrnium creticum (Umbelliferae) were determined. Antioxidant properties of methanol extracts were studied by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method. Among all the Smyrnium taxa, S. olusatrum showed the most potent radical scavenging activities. Antimicrobial activities of these taxa were studied using agar well diffusion method and S. perfoliatum showed broad-spectrum antibacterial activity with inhibition zones ranging from 13 to 25 mm.

Asperula pseudochlorantha var. Antalyensis comb, et stat nov. (Rubiaceae)

Asperula pseudochlorantha Ehrend, and Asperula antalyensis Ehrend, from Turkey were described in 1958. General characteristics, seed structure and micromorphology, pollen measurements and other pollen characteristics were examined to determine the taxonomic status of these taxa. Morphologically, the two taxa cannot be easily distinguished, and the seeds and pollen grains are similar. The chromosome number is 2n = 22 for both taxa. Based on morphological, palynological and cytological similarities, and the fact that both taxa are found in the same habitats, we propose that A. antalyensis should be recognized as A. pseudochlorantha Ehrend, var. antalyensis (Ehrend.)
