Vybrané charakteristiky z biologie významných druhů z čeledi miříkovitých
 Gregorová, Vladislava
ABSTRACT The objective of this study was to compare the germination of cultural and weed variety of selected species of the family Apiceae. There were selected species: Daucus carota and Pastnaca sativa. For this research were selected three stocks of Carrot: Daucus carota -- wild, Daucus carota -- seeded from stored root in the garden - variety Olympus and Daucus carota -- originated from the propagation crop species -- variety Cider. For Pastinaca sativa were selected two populations: Pastinaca sativa - from the propagation crops and Pastinaca sativa - wild. For analyzed species the germination of achenes was determined under laboratory conditions. Average germination detected in Daucus carota - wild was 51%, for carrot Olympus 74% and for carrot Cider 89%. Average germination detected in Pastinaca sativa -- wild was 2%, for long white parsnip varieties 87%. The final germination was entered into tables and was processed to charts. Results were compared, in the discussion there were expressed some conjecture what effects might have contributed to the observed differences. There was also mentioned the possibility of affecting the quality of propagation material impurities of free growing stock.
