Description
  • Response to flooding intensity, estimated as biomass accumulation, was studied in three closely related taxa, Elytrigia repens, E. intermedia and their hybrid. Reduction of nearly all the biomass compartments with increasing flooding intensity was observed in the three taxa. All the three taxa can thus be regarded as flooding-intolerant. E. repens is regarded as the relatively most flooding-tolerant of the three taxa tested, E. intermedia as the least flooding-tolerant, while the hybrid displayed intermediate flooding tolerance. Both Elytrigia species also occur as weeds; E. intermedia in agro-environment in warm regions, E. repens infests places across different types of habitats. Where they co-occur, hybridisation between them may lead to the enrichment of their gene pools with genes responsible for survival of the parental species under extreme conditions and their weedy potential may thus be enhanced.

  • Byl studován vliv zaplavení na rostliny druhů Elytrigia repens, E. intermedia a jejich hybrida. Rostliny byly vystaveny třem intenzitám zaplavení, z nichž ten nejsilnější simuloval úplné zaplavení půdy v přírodě. Tolerance k zaplavení byla vyjádřena množstvím biomasy jednotlivých částí rostlin po zaplavení. Všechny tři druhy lze označit za netolerantní k zaplavení. E. repens snášel zaplavení nejlépe, E. intermedia nejhůře a hybrid vykazoval střední hodnotu tolerance. Oba druhy včetně hybrida koexistují v teplých oblastech ČR i jako plevele a mohou se snadno křížit. Výsledky naznačují, že E. repens může krátkodobě (1 měsíc) růst v zaplavených lokalitách, E. intermedia tam může přežívat. Hybridizace může vést ke zvýšení tolerance k zaplavení u hybrida v porovnání s rodičovským E. intermedia. (cs)
