The article describes the laboratory germination and seed dormancy duration of five Trollius species andfour hybrids, which has been grew ex situ. The species and forms with high seed germination were detected from the dataobtained: T. ledebourii Rchb. (92 %), T. chinensis Bunge (93,5 %) end T. chinensis × T. ledebourii (82 %). Besides a high germination, the T. ledebourii seeds have the short dormancy period (22 days) and good sprouts. Therefore, the T. ledebourii seeds can be recommended for both autumn and spring sowing. The above mentioned Trollius species and forms arepotential for ornamental cultivar creation by further selection. The seeds of following species and forms T. apertus Perf.ex Igoschina, T. europaeus L., T. sajanensis (Malyschev) Sipliv., T. asiaticus × T. sajanensis, T. ledebourii × T. altaicus and T.× cultorum have low germination and long dormancy period. The examination of stratification treatment parameters andagrotechnical measures is needed for the germination of these seeds to get higher.
