Abstract

V diplomskem delu smo analizirali semenski sestoj grške jelke (Abies cephalonica Loud.) pri Komnu. Glavni namen je bil proučiti stanje in kakovost nasada s površino 2,91 ha. Naredili smo polno premerbo vseh grških jelk. Pri nekaterih drevesih so bile prisotne poškodbe, največ jih je bilo abiotskega vzroka, predvsem mraznih razpok. Te imajo lahko velik vpliv na kakovost lesa in zmanjšajo vrednost sortimentov. Pogostnost mraznih razpok nakazuje slabšo prilagojenost grške jelke na lokalno podnebje. Naredili smo tudi analizo mladja. Mladik grške jelke do velikosti 10 cm je največ od vseh drevesnih vrst, a se z večanjem višine število mladik te vrste izrazito zmanjšuje, kar je verjetno tudi posledica močnega objedanja divjadi. Glede na številčnost mladik lahko vidimo, da grška jelka v tem sestoju dobro obrodi in da je seme kaljivo, zato je primerna kot semenski sestoj. Večje potrebe po sajenju grške jelke na Krasu v večjem obsegu za zdaj ni, a bi jo bilo smiselno preizkušati v manjših nasadih še v drugih delih Krasa, ugotoviti, kateri so glavni vzroki za pojavljanje mraznih razpok in preveriti, ali se le-te pojavljajo tudi drugje. Ob nadaljevanju globalnega segrevanja grška jelka kljub naštetim slabostim ostaja potencialno zanimiva vrsta za gojenje na Krasu.

Secondary title:	Greek fir (Abies cephalonica L.) in seed stand at Komen
Secondary abstract:	In the diploma thesis we analyzed the seed stand of Greek fir (Abies cephalonica Loud.) near Komen. The main objective was to study the condition and quality of the seed stand with an area of 2.91 ha. We conducted a complete inventory of all Greek firs. Damage was present in some trees, most of them of abiotic origin, mainly cold cracks. These can have a major impact on the quality of the wood and reduce its value. The frequency of cold cracks indicates an insufficient adaptation of Greek firs to the local climate. We also conducted analyzes of young seedlings. Greek fir seedlings up to 10 cm tall are the most abundant of all tree species on our plot, but seedlings above 10 cm become less abundant with increasing height, probably also due to heavy browsing. From the abundance of seedlings, we can see that Greek fir is reproducing well in this stand, making it suitable as a seed stand. There is no need to plant Greek fir on a larger scale in the Karst now, but it would be useful to test it in smaller stands in other parts of the Karst to find out what the main causes of cold cracks are, and whether they occur elsewhere. In the face of ongoing global warming, Greek fir remains a potentially interesting species to grow in karst, despite the disadvantages mentioned above.
