Conservation of Betula oycoviensis, an endangered rare taxon, using vegetative propagation methods

Popis výsledku v původním jazyce

Ojcow birch (Betula oycoviensis Besser) is a rare Central European tree taxon, micro-populations of which are found in only several localities. With a view to maintaining the B. oycoviensis gene pool, this study tested the species potential for micropropagation, grafting, and propagation by cuttings. Plant material for vegetative propagation was collected from ten genotypes in the Czech Republic. In vitro culture was established from axillary buds surfaces sterilized with 0,1% HgCl2 and cultivated on woody plant (WP) medium supplemented with 1 mg l(-1) 6-benzylaminopurine (BAP). Two genotypes of the species were successfully multiplied by in vitro propagation using WP medium supplemented with 0-2 mg l(-1) BAP. The BAP concentration of 1 mg l(-1) proved to be optimal, yielding 2,5 new shoots per explant in genotype 516 and 3,5 shoots per explant in genotype 545. The shoots were rooted on half-strength Murashige and Skoog (MS) medium supplemented with various concentrations of alpha-naphthylacetic acid
