Abstract

Primorska kozja češnja (Rhamnus intermedius Steud. & Hochst.) je nova predstavnica slovenske flore. Najdena je bila na pašniku na Slovenskem Krasu v bližini vasi Osp. Med različnimi poganjki je bila opažena izredno visoka morfološka variabilnost, zato smo na njej izvedli analizo morfološke variabilnosti. Cilji raziskave so bili preučiti morfološko variabilnost vrste pri nas, ugotoviti njeno ogroženost in za vrsto izdelati določevalni ključ znotraj rodu Rhamnus. Od vseh enajstih najdenih osebkov smo pobrali vzorce za analizo in za primerjavo. Za primerjavo smo analizirali tudi liste razkrečene kozje češnje (Rhamnus saxatilis Jacq.). Z deskriptivno statistiko in neparametričnim Mann-Whitneyjevim U-testom smo potrdili visoko variabilnost znotraj vrste in velike razlike vseh opazovanih morfoloških parametrov, z izjemo dolžine listne ploskve in mesta maksimalne širine listne ploskve.

Secondary title: Morphological variability of Rhamnus intermedius leaves in Slovenia
Secondary abstract: IRhamnus intermedius Steud. & Hochst. is a new representative of the Slovenian flora. It was found on a pasture in the Slovenian Kras near the village of Osp. Due to the high observed morphological variability among different shoots, we performed an analysis of morphological variability. The goals of the study were to examine the morphological variability of the species in Slovenia, determine its vulnerability and create an identification key for the species within the genus Rhamnus. We collected samples for analysis from all eleven known specimens. For comparison we analysed foliage of Rhamnus saxatilis Jacq. Using descriptive statistics and the non-parametric Mann Whitney U-test, we confirmed high variability within the species and large differences in all observed morphological parameters, apart from the length of the leaf and the location of the maximum width of the leaf.
