The variability of natural populations of Brachypodium pinnatum and B. Sylvaticum based on morphological features / Beata Paszko in Acta societatis botanicorum poloniae, vol. 77, n°3 (Année 2008)

Principal component analysis and cluster analysis of morphometric data segregate specimens or populations of Brachypodium into two groups, corresponding to the two species. In most of morphological characters, B. pinnatun and B. sylvaticum are similar to each other. However, in terms of characteristics, such as the hairiness of culms and leaf-sheaths both can also vary much within a single population. In comparison with B. pinnatum, B. sylvaticum always has pubescent abaxial palea surfaces. Apparent differences were not detected between the two ecotypes of B. pinnatumn named "Grassland" and "Woodland"."

Variability and structure of natural populations of Hordeum murinum L. based on morphology / Marta Mizianty in Plant Systematics and Evolution, vol. 261 (Année 2006)

Public [article]  inPlant Systematics and Evolution > vol. 261 (Année 2006) . - pp. 139-150 Titre : Variability and structure of natural populations of Hordeum murinum L. based on morphology Type de document : texte imprimé Auteurs : Marta Mizianty, Auteur Année de publication : 2006 Article en page(s) : pp. 139-150 Langues : Anglais (eng) Catégories : [ZG] Pologne [Espèces (in biblio)] Hordeum murinum Mots-clés : variabilité morphologique  statistiques  nombre de chromosomes  aire de répartition Résumé : "Based on a detailed statistical analysis of 19 quantitative and four qualitative characters of 31 samples of Hordeum murinum from Poland, it was stated that the small variability of these characters does not permit to distinguish any intra-specific units. Only a slight geographical differentiation of populations was found. Based on the differences discovered, the populations have been divided into two groups: one with the centre of distribution in the North-East (group E) and the second in South-west Poland (group W). This differentiation might result from the different routes of migration of this species into Poland. The chromosome number (2n = 28) confirms earlier reports from Poland. New data concerning the distribution of H. murinum in north-eastern Poland are also presented. A detailed study on the distribution of H. murinum in Poland is under way."
