Statistical evaluation of chromosomes of some Lathyrus L. taxa from Turkey

Abstract

In this study, statistical analysis was performed on mitotic metaphase chromosomes of 26 Lathyrus taxa, four of which are endemic. According to the findings obtained as a result of analysis, taxa close to each other were determined. Chromosome characteristics were revealed based on the arm lengths of taxa. Based on these, ANOVA, correlation analysis, PCA and cluster analysis were performed to determine the chromosomal relationships between taxa. Morphological similarities of plant taxa and chromosomal statistics results may not be always parallel to each other. According to Cluster Analysis, especially L. hirsutus - L. odoratus, L. brachypterus subsp. haussknechtii - L. phaselitanus, L. stenophyllus - L. chloranthus, L. gorgoni var. gorgoni, - L. nissolia - L. pratensis, L. tuberosus - L. annuus taxa are closely related.

A statistical overview to the chromosome characteristics of some Centaurea L. taxa distributed in the Eastern Anatolia (Turkey)

“…Moreover, it has no linear relationship in taxonomic terms. Genç et al (2021) reached the same conclusion in their study. Accordingly, chromosomal formulas are not suitable for evaluating together with each other to draw a meaningful conclusion.…”

“…No statistical study of this scale has been encountered based on chromosome characteristics on the genus. In some studies, the cluster analysis data can yield similar trees with the morphological classification of the taxa (Açar & Satıl 2019;Arabaci et al, 2021;Dirmenci et al 2019;Genç et al 2021). Wagenitz (1975) divided the genus Centaurea into 34 sections in Flora of turkey.…”

Comparative karyological analysis of some Turkish Cuscuta L. (Convolvulaceae)

“…For this reason, considering the characters in classical taxonomy, examining the chromosome numbers, structure and structures gives beneficial results in solving the problems (Taşar et al, 2018a;2018b ). In addition, statistical analyzes can be useful in morphological and anatomical studies recently (Genç et al 2021;Arabacı et al 2021;Dirmenci et al 2019;Dirmenci et al 2020;Açar and Satıl 2019;Açar and Taşar 2022). This study aims to reveal the karyological features of Cuscuta species distributed in Turkey, determine the relationships between them, and contribute to the genus's taxonomic classification.…”
