Razvoj tehnik generativnega razmnoževanja navadnega koprivovca (Celtis australis L.) : magistrsko delo - 2. stopnja = Developing techniques for generative propagation of european nettle tree (Celtis australis L.) : M. Sc. Thesis - master study programmesFlajs, NikaV 19. stoletju so ogolela kraška območja pogozdili z neavtohtonim črnim borom (Pinus nigra Arnold), čigar najstarejši sestoji se danes že redčijo. V spodnji plasti se znova pojavljajo drevesne vrste ... avtohtonih listavcev, med katere sodi tudi navadni koprivovec (Celtis australis L.). Vse lastnosti navadnega koprivovca kažejo na njegovo primernost za vnašanje v kraške gozdove tako z ekološkega kot tudi z gospodarskega vidika. Ker pa je certificirane gozdne sadike navadnega koprivovca v Sloveniji trenutno nemogoče dobaviti, je smiselno preučiti možnosti za uspešno domače generativno razmnoževanje in vzgojo kakovostnih sadik. Iz tega razloga je bil osnovan poskus, v katerem smo preučevali uspešnost različnih metod generativnega razmnoževanja navadnega koprivovca. Primerjali smo kalivost glede na različen čas nabiranja semena, kraj setve in čas setve ter uspešnost dodatne obdelave semena pred setvijo. Za najuspešnejšo metodo se je izkazala jesenska setev na prosto s 93 % kalivostjo. Nekoliko nižjo, a vseeno zadovoljivo kalivost (77,8 %) je imelo po hladni stratifikaciji spomladi na prosto posejano seme. Povsem drugače se je v poskusu izkazala setev v gojitvene plošče, položene v kalilnik, kjer je povprečna kalivost znašala le 1,6 %. Dodatna obdelava semena se je izkazala za nepotrebno, saj med različno obdelanim semenom ni bilo značilnih razlik v kalivosti. Ker rezultati niso pokazali značilnih razlik v kalivosti med septembra in oktobra nabranim semenom, je priporočljivo čimprejšnje nabiranje plodov že v septembru oziroma takoj, ko se plodovi črnovijolično obarvajo.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [N.
