Abstract

Rod Aurinia Desv. pripada tribusu Alysseae unutar porodice Brassicaceae. Vrste roda Aurinia rasprostranjene su poglavito na Balkanskom i Apeninskom poluotoku. Zbog preklapanja morfoloških značajki plodova i sjemenaka pet vrsta (A. corymbosa, A. leucadea, A. petraea, A. saxatilis, A. sinuata) i podvrste (A. petraea subsp. microcarpa) teško je iste sa sigurnošću odrediti. Cilj diplomskog rada stoga je bio opisati morfološku varijabilnost plodova i sjemenki istraživanih vrsta, utvrditi postoje li jasne morfološke razlike u građi plodova i sjemenki te izraditi determinacijski ključ. Istraživanje je provedeno na 372 herbarijska lista pohranjena u zbirkama ZA, ZAHO, ZAGR, BEO, BEOU i BUNS. Promatrano je 11 morfoloških značajki. Za razlikovanje vrsta najznačajnijim pokazale su se broj sjemenki u jednom lokulu, duljina ploda, širina ploda, omjer duljine i širine ploda, duljina stapke ploda, duljina sjemenke te širina sjemenke. Za razlikovanje podvrste A. petraea subsp. microcarpa od A. corymbosa i A. petraea najznačajnijim pokazale su se duljina ploda, duljina stapke ploda, duljina sjemenke i širina sjemenke te je ustanovljeno da plod i sjemenka A. petraea subsp. microcarpa više nalikuje plodu i sjemenki A. corymbosa. Na temelju morfološke analize predložen je novi determinacijski ključ u kojem je većina upotrebljenih morfometrijskih značajki pokazala uži raspon od onih ranije navedenih u literaturi.

Abstract (english)

Genus Aurinia Desv. belongs to the Alysseae tribe within the Brassicaceae family. Species of the genus Aurinia are distributed mainly on the Balkan and Apennine peninsulas. Due to the overlap of morphological characteristics of fruits and seeds of five species (A. corymbosa, A. leucadea, A. petraea, A. saxatilis, A. sinuata) and one subspecies (A. petraea subsp. microcarpa), it is difficult to determine each one with certainty. The aim of the thesis was to describe the morphological variability of fruits and seeds, to determine whether there are clear morphological differences in the structures and to make a determination key. The research was conducted on 372 herbarium lists stored in the ZA, ZAHO, ZAGR, BEO, BEOU and BUNS collections. 11 morphological features were observed. The number of seeds in one loculus, siliculae length, siliculae width, siliculae length to width ratio, pedicels length, seed length and width proved to be the most significant for distinguishing species. To distinguish the subspecies A. petraea subsp. microcarpa from A. corymbosa and A. petraea, fruit length, pedicels length, seed length and width proved to be the most significant so the fruit and seed of A. petraea subsp. microcarpa more closely resembles A. corymbosa. Based on the morphological analysis, a new determination key was proposed. Therein most morphometric characters have a narrower range than those previously reported in the literature.
