Název v původním jazyce

Effect of nitrogen, appendage removal, locality, and year on seed germination of the endangered dry grassland species Pulsatilla pratensis (L.) Mill.

Popis výsledku v původním jazyce

Pulsatilla pratensis (L.) Mill. is a plant species widely used for ornamental purposes in gardens, but in nature it grows in dry grasslands and is considered an endangered species whose seeds can be directly affected by higher nitrogen (N) deposition. Here we investigate how the germination of Pulsatilla pratensis is affected by concentrations of dissolved nitrogen (NH4 + and NO3 - ions), appendage removal, the locality of seed origin, and the year of seed collection. Seeds from different years and twolocalities, one on clay shale and the other on limestone, were germinated under laboratory conditions in solutions of NH4NO3 ranging from 0 to 4239 mg l-1 N. Mean germination of seeds from the clay shale locality in 2009 and 2011 and from the limestone locality in 2011 across treatments with low concentrations of N (0-170 mg l-1 N) ranged between 35-49%. Seeds were able to germinate under a wide range of N concentrations, and a substantial decrease in germination ratewas recorded only if
