Abstract
Mature seeds ofTaxus baccata L. andTaxus baccata L.fastigiata Loudon contain embryos which are both immature and dormant. Embryo cultures were carried out in order to test the relative effciency of gibberellins (GA3 and GA4), chilling and leaching. The increase of germination percentages depends on the treatment applied and the tested variety. WithTaxus baccata, the germination of which is very difficult, a double treatment either leaching and gibberellins or leaching and chilling are necessary to obtain a high percentage of germination. Our results are compared with facts already known on mature dormant embryos of other plants. Kultur embryíTaxus baccata L. aTaxus baccata L.fastigiata Loudon bylo použito k testování relativní účinnosti giberelinů (GA3 a GA4), zchlazování a vymývání. Vzestup klíčivosti záleží na použitém postupu a na testované odrůdě. U obtížně klíčícíhoTaxus baccata je k dosažení vysoké klíčivosti nutné dvojité půaobení, bud zchlazení a gibereliny, nebo zchlazení a vymývání.Keywords
