Abstract:Gynodioecious Daphne laureola L. is one of six species of the genus Daphne L. native to Slovenia. The main goals of this research were to determine the distribution of Daphne laureola in the Bohor area, the sexual structure of populations and its correlation with site conditions, and whether morphological differences exist between females and hermaphrodites beyond those of flower structure. Four research plots located on the north side of Bohor were selected - two in each altitude range. A total of 277 plants were studied to determine the sexual structure of the populations, 90 of which were additionally studied for sexual dimorphism. The species was recorded for the first time in quadrant 9959/1 of the Central European flora mapping grid, extending its previously known distribution. The share of female plants was between 3.17% and 47.17% and was lower at higher altitudes. The frequency of plants, morphological traits, and the proportion of female individuals are highly correlated with environmental factors. Plants bore more flowers at higher altitudes, and leaves were longer, with rounder tips and sharper bases.The majority of morphological differences between females and hermaphrodites were minor and not statistically significant.

Title:Spolni dimorfizem in razširjenost lovorolistnega volčina (Daphne laureola L.) na območju Bohorja
Abstract:Ginodiecična vrsta lovorolistni volčin (Daphne laureola L.) je ena od šestih samoniklih vrst iz rodu volčin (Daphne) v Sloveniji. Cilji raziskave so bili: ugotoviti razširjenost lovorolistnega volčina na Bohorju, spolno strukturo populacij na izbranih ploskvah lovorolistnega volčina na Bohorju in njeno povezavo z rastiščnimi razmerami ter ali poleg razlike v cvetovih obstajajo šedruge značilne morfološke razlike med obojespolnimi in ženskimi rastlinami. V raziskavo so bile vključene štiri ploskve na severnem delu Bohorskega pogorja, in sicer po dve v vsakem višinskem pasu. Skupno je bilo za preučevanje spolne strukture populacij popisanih 277 osebkov, med njimi pa še 90 osebkov za preučevanje spolnega dimorfizma. Poleg že prej znane razširjenosti smo vrsto prvič doslej zabeležili v kvadrantu 9959/1 kartiranja srednjeevropske flore. Delež ženskih rastlin po ploskvah se je gibal med 3,17 % in 47,17 % in je bil obratno sorazmeren z naraščanjem nadmorske višine. Pogostnost pojavljanja, deleži ženskih rastlin in morfološke lastnosti rastlinso bile odvisni od dejavnikov okolja. Grmi so imeli na višji nadmorski višini več cvetov, listi pa so bili daljši, z bolj topim vrhom listne ploskve in ostrejšim dnom listne ploskve. Morfološke razlike med obojespolnimi in ženskimi osebki so bile majhne in večinoma niso bile statistično značilne.
