چکیده
A Sorbus bakonyensis (Jáv.) Jáv. (syn. S. majeri Barabits) a Bakony egy igen szűk elterjedésű apomiktikus kisfaja. Korábbi adatait kizárólag Márkó feletti Kopasz-hegyről (~Kápolnadomb, Csordás-árok) közölték. Részletes térképezéssel sikerült kissé bővíteni faj areáját Kopasz-hegytől nyugatra (Kis-Bükk hegy) és keletre is. egyedszáma (hat fatermetű egyed változó számú magonc) kis kiterjedésű (~2 km2) areája miatt természetvédelmi státusza kritikusan veszélyeztetett. Állományára nézve magas nagyvadlétszám (vaddisznó, gímszarvas) az egyre gyakoribb aszályos időszakok egyaránt jelentős veszélyeztető tényezők. in situ megőrzése még reális cél, de ex situ, faiskolában történő felszaporítása feltérképezett area megfelelő élőhelyeire (nyiladékok, erdőszegélyek) visszatelepítése is indokolt.

متن کاملInheritance of the chloroplast genome in Sorbus aucuparia L. (Rosaceae).
Chloroplast DNA (cpDNA) inheritance was investigated in Sorbus aucuparia using progenies obtained from six controlled crosses between individuals of known haplotype. Polymerase chain reaction (PCR) amplification, followed by restriction analysis, was used to characterize 248 offspring for either of two polymorphic cpDNA fragments. All offspring exhibited the maternal haplotype, which indicates ...
