Razširjenost in ogroženost lesnike (Malus sylvestris Mill.) v Sloveniji : magistrsko delo - 2. stopnja

Kišek, Mateja (avtor), Brus, Robert (mentor)

Lesnika (Malus sylvestris Mill.) je v Sloveniji samonikla manjšinska drevesna vrsta. V raziskavi smo ugotavljali njeno razširjenost in ogroženost v Sloveniji. Ob pomoči morfometrijske analize listov in plodov smo analizirali 97 dreves iz 9 populacij. Preverjali smo 12 morfoloških znakov na listih in 8 morfoloških znakov na plodovih. Rezultati kažejo, da je lesnika v Sloveniji redka in ogrožena drevesna vrsta. V naši raziskavi na podlagi dveh najznačilnejših morfoloških znakov % dlakavosti listov in premera plodov % le 44,42 % dreves predstavlja pravo lesniko, 55,58 % pa verjetne križance z žlahtno jablano (Malus % domestica). V splošnem imamo v Sloveniji zaradi veliko površin v zaraščanju ugodne habitatne razmere za rast lesnike. Ogrožena je predvsem zaradi križanja z žlahtno jablano, gozdarji pa ji pri gojenju še vedno namenjajo premalo pozornosti. Za dolgoročno ohranjanje bo lesniko treba čim bolj upoštevati pri gojenju gozdov in več pozornosti bo potrebno posvetiti poreklu in sledljivosti sadik. Nujno bi bilo oblikovanje preverjenega gozdnega semenskega objekta ali mreže dreves, ki bi omogočala vzgojo gensko ustreznega gozdnega reprodukcijskega materiala lesnike

Izvleček

Common crab apple (Malus sylvestris Mill.) is a minor tree species native to Slovenia. In the study we have researched the distribution and endangerment of common crab apple in Slovenia. We analyzed 97 trees from 9 populations. We performed the morphometrical analysis of leaves and fruits. We examined 12 morphological traits of the leaves and 8 morphological traits of the fruits. The results show that the common crab apple is a threatened and rare tree species in Slovenia. In our study, based on two of the most characteristic morphological traits % hairiness of leaves and fruit diameter, only 44,42 % of the studied trees represent the common crab apple and the other 55,58 % are potential hybrids with orchard apple (Malus % domestica Borkh.). Generally, in Slovenia there is a lot of appropriate habitats for common crab apple, due to more and more extensive overgrown areas. Common crab apple in Slovenia is endangered mainly because of hybridization with orchard apple. The second reason is contempt of common crab apple in the silviculture. For long-term conservation common crab apple should be taken into account as much as possible in silviculture and there should be more vigilance in checking traceability of seedlings. It is necessary to isolate forest seed objects or network of individual trees with the appropriate genetic code.
