Abstract

Navadna rosnica (F. officinalis L.) je v Sloveniji zastopana z dvema podvrstama: F. officinalis subsp. officinalis in F. officinalis subsp. wirtgenii (Koch) Arcangeli (Wraber, 2007), ki doslej pri nas še nista bili raziskani. Namen mojega diplomskega dela je bil raziskati uporabnost morfoloških razlikovalnih znakov za določanje podvrst navadne rosnice, določiti ves razpoložljivi material F. officinalis iz herbarija LJU na Oddelku za biologijo Biotehniške fakultete Univerze v Ljubljani ter na osnovi te revizije ugotoviti, kako sta podvrsti razširjeni v Sloveniji. V morfometrično študijo smo vključili 62 herbarijskih pol vrste Fumaria officinalis (s. lat.). Na rastlinah sem izmerila 11 kvantitativnih znakov, ocenila stanja 4 atributivnih znakov in izračunala 3 razmerja med kvantitativnimi znaki. Podvrsti se med seboj najbolje razlikujeta po obliki vrha ploščice gornjega venčnega lista, dolžini venca, širini krila na ploščici gornjega venčnega lista, širini ploščice gornjega venčnega lista, razmerju med širino krila in širino zelene osrednje žile, razmerju med širino ploščice in širino žebice gornjega venčnega lista ter številu cvetov v socvetju. Razlik v barvi venca in čaše zaradi herbarizacije nisem mogla potrditi. Znaki na plodu so se izkazali za neuporabne. Od 62 herbarijskih pol, ki so predstavljale moj vzorec, je bilo le 8 herbarijskih pol določenih do podvrste (13 %). Po zaključku naše revizije je delež določenosti narasel na 82 %. Glede na rezultate moje raziskave je podvrsta F. officinalis subsp. wirtgenii razširjena predvsem v submediteranskem in preddinarskem območju, nekaj podatkov pa je tudi iz predalpskega območja. F. officinalis subsp. officinalis najdemo skoraj po vsej državi, razen v alpskem območju, najbolj pa razširjena je v predalpskem in submediteranskem območju. Naša raziskava je bistveno dopolnila poznavanje razširjenosti F. officinalis subsp. wirtgenii, ki je bila do sedaj znana le iz enega kvadranta (Jogan, 2001) in prvič prikazala razširjenost F. officinalis subsp. officinalis v Sloveniji.

Secondary title: Subspecies of common fumitory (Fumaria officinalis L.) in Slovenia
Secondary abstract: In Slovenia F. officinalis L. comprisses two subspecies (F. officinalis subsp. officinalis and F. officinalis subsp. wirtgenii (Koch) Arcangeli), which have not been studied in our country so far. The purpose of my thesis was to investigate the morphological characters for identification of the subspecies, to identify all available F. officinalis material from the LJU herbarium at the Department of Biology, Faculty of Biotechnology, University of Ljubljana, and to find out how these subspecies are distributed in Slovenia. In the morphometric study we included 62 herbarium sheets of F. officinalis (s. lat.). I measured 11 quantitative characters, 4 attributive characters, and I calculated 3 ratios between certain quantitative characters. The subspecies are best distinguished by the shape of the top limb of the upper petal, length of corolla, the width of the wing on the limb the upper petal, the width of the limb of the upper petal, the ratio of the width of the wing to the green central vein, the ratio of the width of the limb to the claw of the upper petal and the number flowers in the inflorescence. The difference in the color of the petals and sepals could not be confirmed due to herbarization. The fruit characters proved to have no discriminative value. Of the 62 herbarium sheets in the study, only 8 were identified to the subspecies level (13 %). After our revision, the percentage of identification increased to 82 %. According to the results of my research, the subspecies F. officinalis subsp. wirtgenii is widespread mainly in the Submediterranean and Predinaric regions, with a few data also from the Prealpine region. F. officinalis subsp. officinalis is found almost all over the territory, except in the Alpine region, and is most common in the Prealpine and Submediterranean region. Our study significantly complemented the knowledge of the distribution of F. officinalis subsp. wirtgenii, known so far from only one quadrant (Jogan, 2001). The distribution map of F. officinalis subsp. officinalis in Slovenia is published for the first time.
