Rdečeplodni brin (Juniperus Oxycedrus l.) v Sloveniji : diplomsko delo - univerzitetni študij

Škrlj, Matej (author), Brus, Robert (mentor)

V diplomski nalogi je predstavljen rdečeplodni brin (Juniperus oxycedrus L.), ena od štirih avtohtonih vrst iz rodu Juniperus v Sloveniji. Glavni cilji raziskave so bili ugotoviti njegovo geografsko razširjenost, spolni dimorfizem, morfološko variabilnost med populacijami in znotraj njih ter preveriti navedbe o pojavljanju veleplodnega brina v Sloveniji. Rdečeplodni brin smo našli na Koprskem, ob Dragonji, na Kraškem robu pri Sočergi in nad Lijakom v Vipavski dolini. V analizo je bilo skupno zajetih 11 populacij, 136 grmov, približno 6800 iglic in 1600 storžkov. Preučevali smo devet morfoloških lastnosti na iglicah in dve na storžkih. Največje iglice smo zabeležili v populaciji Koštabona, največje storžke pa nad Lijakom. Povprečne vrednosti velikosti iglic niso potrdile hipoteze o prisotnosti veleplodnega brina (Juniperus macrocarpa Sibth. & Sm.) na proučevanih lokacijah, saj so bile izmerjene vrednosti izrazito manjše od navedenih v literaturi za to vrsto. Ugotovili smo izrazito deltasto obliko iglic, kakršno za domnevno vrsto Juniperus deltoides R.P.Adams sicer navaja R. P. Adams. Spolni dimorfizem se je pokazal pri vseh morfoloških lastnostih iglic, vendar različno znotraj posameznih populacij. Največ značilno različnih lastnosti med spoloma je v populaciji Koštabona, najmanj pa v populaciji Labor.

• Title: Prickly juniper (Juniperus oxycedrus L.) in Slovenia

Abstract

In graduating thesis is presented Prickly Juniper (Juniperus oxycedrus L.), one of the four indigenous species of juniper in Slovenia. The aim of this study was to determine its geographical distribution, gender dimorphism, morphological variability among populations and within them and to examine the eventual presence of Juniperus macrocarpa Sibth. & Sm. in Slovenia. Prickly Juniper was found in Koper Area, at Dragonja Valley, on the Karst Edge in Sočerga and above Lijak in the Vipava Valley. The study analysed 11 populations, 136 trees, about 6800 leaves and 1600 cones. Nine morphological traits were studied on leaves and two on the cones. The largest leaves were found in the Koštabona population and the largest cones in Lijak. The average values of leaves size did not confirm the hypothesis of the presence of J. macrocarpa in the study area, as the measured values were significantly smaller than stated in the literature for this species. Average leaf shape in the study area is clearly %delta-shaped%, which is by R. P. Adams stated to be eventual new species J. deltoides R.P.Adams Gender dimorphism was found in all of the morphological traits of leaves, but different within individual populations. Most significantly different characteristics between genders were in Koštabona population and the least in the population of Labor.
