Vegetative and generative propagation of the endangered species Daphne cneorum L.

Popis výsledku v původním jazyce

There were used two different ways of vegetative propagation of Daphne cneorum: micropropagation and propagation by cuttings. Presence of auxine in the nutrient medium had a positive influence compared to the control in micropropagation. On the other hand, there were small differences in effect of growth stimulants IAA, IBA, NAA on rooting (62?64%) of microcuttings. The rooting ability of cuttings from gene pool areas was higher in comparison with cuttings from natural localities. The genotype and yearof cuttings taking influenced the rooting ability of cuttings, too. The percentage of rooting cuttings was higher (39?100%) using propagation by cuttings than in vitro propagation (38?74%) ? however, in case of taking cuttings from gene pool areas. In generative propagation, we achieved to obtain seeds from 3?12% of pollinated flowers. Fruit formation and seed germinability were in particular years variable because of weather influence.
