Abstract
Two co-occurring dominant wetland helophytes and potential competitors, Phragmites australis and Glyceria maxima, were cultivated under N, P availabilities simulating the trophic status of wetlands with different fertility (oligo- and eutrophic). In the present study, both species responded similarly to nutrient surplus. The enhanced growth, delayed shoot senescence, and delayed retranslocation of N into belowground organs were found in both species in eutrophic treatment. Furthermore, N levels remaining in dry leaves were proportionally related to those in living ones, being significantly higher in eutrophic treatment.
Abstract (in Czech)
Výzkum reakcí dvou druhů mokřadních rostlina na zvýšený přísun minerálních živin. Oba zkoumané druhy - rákos i zblochan, reagovaly podobně - zrychlený růst, oddálené stárnutí nadzemních částí, zpožděné ukádání zásobních látek do podzemních orgánů.
