Razširjenost in ogroženost lesnike (Malus sylvestris Mill.) v Sloveniji : magistrsko delo - 2. stopnja = Distribution and endangerment of common crab apple (Malus sylvestris Mill.) in Slovenia : M. Sc. Thesis - master study programmes
Kišek, Mateja
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
